January 25, 2001: WTC Construction Manager Says Tower Could Sustain Multiple Plane Impacts
Frank De Martini. [Source: New York Times] Frank De Martini, an architect who works as the World Trade Center’s construction manager, is interviewed for a History Channel documentary about the WTC towers. He says, “I believe the building probably could sustain multiple impacts of jetliners because this structure is like the mosquito netting on your screen door, this intense grid, and the jet plane is just a pencil puncturing the screen netting. It really does nothing to the screen netting.” [DWYER AND FLYNN, 2005, PP. 149] De Martini will be in his office on the 88th floor of the North Tower when it is hit on 9/11. He will die when the tower collapses, after helping more than 50 people escape.

March 4, 2001: Television Show Eerily Envisions 9/11 Attacks

An advertisement for the Lone Gunmen show. [Source: Fox] Contradicting later claims that no one could have envisioned what happened on 9/11, the pilot episode of a short-lived Fox television program involves a scenario chillingly similar to the attacks that occur six months later. In the episode of The Lone Gunmen, which is a spin-off of the popular show The X-Files, a small, radical faction within the US government takes over a large passenger jet plane from the ground, using remote control, and then tries to crash it into the World Trade Center. Their intention is to blame the attack on foreign terrorists and therefore revive the arms race. Their plot is thwarted at the last moment, with the pilots regaining control of the plane and steering it upwards over the Twin Towers. [KNIGHT RIDDER, 9/14/2001; JACK MYERS REPORT, 6/20/2002 ] In the program, the plane is destined for Boston, where two of the hijacked aircraft will in fact take off from on 9/11. [FOX TELEVISION, 3/4/2001; BOSTON GLOBE, 9/12/2001] One of its stars, Bruce Harwood, later calls the storyline a “strange awful coincidence,” adding, “[W]ho knows if it was the source of inspiration for September 11.” [MIRROR, 11/26/2002] Ratings are good for the show, with 13 million people watching it. [TV GUIDE, 3/9/2001] Yet despite the similarity to the actual attacks on the WTC, there will be very little commentary about this after 9/11. Media commentator Jack Myers later observes, “This seems to be collective amnesia of the highest order.” [JACK MYERS REPORT, 6/20/2002 ] A best selling 1994 novel by Tom Clancy had similarly included a large passenger jet used as a weapon, being deliberately crashed into the US Capitol building (see August 17, 1994).

April 2001: Speculation That Commercial Pilots Could Be Al-Qaeda Operatives A source with al-Qaeda connections speculates to US intelligence that “bin Laden would be interested in commercial pilots as potential terrorists.” The source warns that the US should not focus only on embassy bombings, because al-Qaeda is seeking “spectacular and traumatic” attacks along the lines of the WTC bombing in 1993. Because the source is offering personal speculation and not hard information, the information is not disseminated widely.

May 2001: Iranian Tells of Plot to Attack WTC An Iranian in custody in New York City tells local police of a plot to attack the WTC. No more details are known. [FOX NEWS, 5/17/2002] Interestingly, an Iranian in prison in Germany will also warn of an attack on the WTC (see Early September 2001), but it is not known if the two cases are related.

May 11, 2001: New York City Practices for Biological Terrorist Attack New York City’s Office of Emergency Management (OEM), which is located in World Trade Center Building 7, organizes a bio-terrorism drill where militant extremists attack the city with bubonic plague and Manhattan is quarantined. The “tabletop exercise” is called RED Ex—meaning “Recognition, Evaluation, and Decision-Making Exercise” —and involves about seventy different entities, agencies, and locales from the New York area. Federal legislation adopted in 1997 requires federal, state, and local authorities to conduct regular exercises as part of the Domestic Preparedness Program (DPP). The US Defense Department chose New York City as the venue for RED Ex due to its size, prominence, and level of emergency preparedness. Various high-level officials take part, including Mayor Rudolph Giuliani, OEM Director Richard Sheirer, Fire Commissioner Thomas Von Essen, and Police Commissioner Bernard Kerik. Agencies and organizations that participate include New York City Fire Department, New York City Police Department, the FBI, and the Federal Emergency Management Agency (FEMA). The exercise is supposedly so intense that, according to one participant, “five minutes into that drill, everybody forgot it was a drill.” [NEW YORK CITY GOVERNMENT, 5/11/2001; NEW YORK CITY GOVERNMENT, 9/5/2001, PP. 74 ; NEW YORK SUN, 12/20/2003; 9/11 COMMISSION, 5/18/2004] According to OEM Director Richard Sheirer, “Operation RED Ex provided a proving ground and a great readiness training exercise for the many challenges the city routinely faces, such as weather events, heat emergencies, building collapses, fires, and public safety and health issues.” [NEW YORK CITY GOVERNMENT, 5/11/2001] In his prepared testimony before the 9/11 Commission, Bernard Kerik later states: “The City, through its OEM, had coordinated plans for many types of emergencies; and those plans were tested frequently.” The types of emergencies they prepared for, he states, included “building collapses” and “plane crashes.” [9/11 COMMISSION, 5/18/2004 ] Considering Richard Sheirer’s comments, RED Ex appears to be one example where the city tests for building collapses. Details about training for airplanes crashing into New York City remain unknown. The second part of this exercise, called Tripod, is scheduled to take place in New York on September 12, 2001, but is cancelled due to the 9/11 attacks.

June or July 2001: Hijackers Plan Attacks from German University Mohamed Atta, Marwan Alshehhi, and an unknown third person are seen in the ground-floor workshops of the architecture department at this time, according to at least two witnesses from the Hamburg university where Atta had studied. They are seen on at least two occasions with a white, three-foot scale model of the Pentagon. Between 60 and 80 slides of the Sears building in Chicago and the WTC are found to be missing from the technical library after 9/11. [SUNDAY TIMES (LONDON), 2/3/2002] A Hamburg friend of Atta’s, Margritte Schroeder, will confirm that Atta is in Hamburg around this time, saying later in 2001, “I saw him here in early July and he was as nice as ever.” Other eyewitnesses see Atta and Alshehhi in Hamburg as well. But there is no record of Alshehhi leaving the US around this time, which suggests that he travels on a false passport for this trip.

June-September 11, 2001: CD Cover Depicts Scene Much Like 9/11 Attacks on WTC

The original cover design for The Coup’s album Party Music. [Source: 75 Ark] Cover artwork is designed for a forthcoming CD, which looks eerily like the attack on the World Trade Center that occurs three months later. The CD, “Party Music,” is the fourth album by a little-known hip-hop group called The Coup, which is known for its political activism. [CNN, 9/13/2001; WASHINGTON POST, 5/22/2002] The intended cover design shows the two members of the group standing in front of the Twin Towers. One of them is pressing a button on a guitar tuner, as if it was a detonator, and two fireballs are exploding from the top floors of the WTC above them. [VILLAGE VOICE, 11/2/2001] Days after 9/11, Wired magazine comments, “If it weren’t for the super-imposed images of the Oakland, California, hip-hop duo known as The Coup, the scene could pass for a remarkably precise replica of the horrific tragedy that befell New York City on Tuesday morning.” The CD is in fact initially scheduled for release in early September, but at some point before 9/11, it is pushed back two months for release in November. Furthermore, as Wired describes, “Timing of the original album printing was disturbingly in sync with real-world events. The printers were set to crank out copies of the fiery World Trade Center image on Tuesday [September 11]… when the label put in a last-minute call, urging them to stop the presses.” [WIRED NEWS, 9/13/2001] The group’s lead member, Raymond “Boots” Riley, is described by Kansas City newspaper The Pitch as a “confessed communist” who “has built a career out of making bold political statements.” [PITCH, 11/8/2001] Riley later says he’d come up with the idea for the CD cover along with his photographer, and they’d finished work on it by the beginning of June. He says, “Any similarities [with 9/11] are totally coincidental, and it was originally supposed to be more of a metaphor for destroying capitalism—where the music is making capitalist towers blow up.” [STRANGER, 9/20/2001] A new cover will be designed and used when the CD is eventually released. [PITCH, 11/8/2001] But copies are sent out prior to 9/11 to members of the press and others, and reviews appear in several publications before September 11 that show the original cover artwork of the exploding WTC.

June 12, 2001: Sting Operation Exposes Al-Qaeda, ISI, and Drug Connections; Investigators Face Obstacles to Learn More

Kevin Ingram, Randy Glass, and Diaa Mohsen in August 1999. [Source: Getty Images] (click image to enlarge) Operation Diamondback, a sting operation uncovering an attempt to buy weapons illegally for the Taliban, bin Laden, and others, ends with a number of arrests. An Egyptian named Diaa Mohsen and a Pakistani named Mohammed Malik are arrested and accused of attempting to buy Stinger missiles, nuclear weapon components, and other sophisticated military weaponry for the Pakistani ISI. [CNN, 6/15/2001; SOUTH FLORIDA SUN-SENTINEL, 8/23/2001; WASHINGTON POST, 8/2/2002] Malik appears to have had links to important Pakistani officials and Kashmiri militants, and Mohsen claims a connection to a man “who is very connected to the Taliban” and funded by bin Laden. [WASHINGTON POST, 8/2/2002; MSNBC, 8/2/2002] Some other ISI agents came to Florida on several occasions to negotiate, but they escaped being arrested. They wanted to pay partially in heroin. One mentioned that the WTC would be destroyed. These ISI agents said some of their purchases would go to the Taliban in Afghanistan and/or militants associated with bin Laden. [WASHINGTON POST, 8/2/2002; MSNBC, 8/2/2002] Both Malik and Mohsen lived in Jersey City, New Jersey. [JERSEY JOURNAL, 6/20/2001] Mohsen pleads guilty after 9/11, “but remarkably, even though [he was] apparently willing to supply America’s enemies with sophisticated weapons, even nuclear weapons technology, Mohsen was sentenced to just 30 months in prison.” [MSNBC, 8/2/2002] Malik’s case appears to have been dropped, and reporters find him working in a store in Florida less than a year after the trial ended. [MSNBC, 8/2/2002] Malik’s court files remain completely sealed, and in Mohsen’s court case, prosecutors “removed references to Pakistan from public filings because of diplomatic concerns.” [WASHINGTON POST, 8/2/2002] Also arrested are Kevin Ingram and Walter Kapij. Ingram pleads guilty to laundering $350,000 and he is sentenced to 18 months in prison. [CNN, 6/15/2001; BLACK ENTERPRISE, 6/19/2001; ASSOCIATED PRESS, 12/1/2001] Ingram was a former senior investment banker with Deutsche Bank, but resigned in January 1999 after his division suffered costly losses. [BLACK ENTERPRISE, 6/19/2001; JERSEY JOURNAL, 6/20/2001] Walter Kapij, a pilot with a minor role in the plot, is given the longest sentence, 33 months in prison. [CNN, 6/15/2001; BLACK ENTERPRISE, 6/19/2001; PALM BEACH POST, 1/12/2002] Informant Randy Glass plays a key role in the sting, and has thirteen felony fraud charges against him reduced as a result, serving only seven months in prison. Federal agents involved in the case later express puzzlement that Washington higher-ups did not make the case a higher priority, pointing out that bin Laden could have gotten a nuclear bomb if the deal was for real. Agents on the case complain that the FBI did not make the case a counterterrorism matter, which would have improved bureaucratic backing and opened access to FBI information and US intelligence from around the world. [WASHINGTON POST, 8/2/2002; MSNBC, 8/2/2002] Federal agents frequently couldn’t get prosecutors to approve wiretaps. [COX NEWS SERVICE, 8/2/2002] Glass says, “Wouldn’t you think that there should have been a wire tap on Diaa [Mohsen]‘s phone and Malik’s phone?” [WPBF 25 (WEST PALM BEACH), 8/5/2002] An FBI supervisor in Miami refused to front money for the sting, forcing agents to use money from US Customs and even Glass’s own money to help keep the sting going.

(Before July 24, 2001): Risk Assessment Identifies Aircraft Striking WTC as One of the ‘Maximum Foreseeable Losses’ A property risk assessment report is prepared for Silverstein Properties before it acquires the lease for the World Trade Center (see July 24, 2001). It identifies the scenario of an aircraft hitting one of the WTC towers as one of the “maximum foreseeable losses.” The report says, “This scenario is within the realm of the possible, but highly unlikely.” Further details of the assessment, such as who prepared it, are unreported.

July 24, 2001: World Trade Center Ownership Changes Hands for the First Time

Larry Silverstein. [Source: Silverstein Properties publicity photo] Real estate development and investment firm Silverstein Properties and real estate investment trust Westfield America Inc. finalize a deal worth $3.2 billion to purchase a 99-year lease on the World Trade Center. The agreement covers the Twin Towers, World Trade Center Buildings 4 and 5 (two nine-story office buildings), and about 425,000 square feet of retail space. [NEW YORK TIMES, 4/27/2001; PORT AUTHORITY OF NEW YORK AND NEW JERSEY, 7/24/2001; IREIZINE, 7/26/2001] Westfield America Inc. will be responsible for the retail space, known as the Mall. Silverstein Properties’ lease will cover the roughly 10 million square feet of office space of the Twin Towers and Buildings 4 and 5. Silverstein Properties already owns Building 7 of the WTC, which it built in 1987. This is the only time the WTC has ever changed hands since it was opened in 1973. [INTERNATIONAL COUNCIL OF SHOPPING CENTERS, 4/27/2001; WESTFIELD GROUP, 7/24/2001; DAILY TELEGRAPH, 9/11/2001; NEW YORK TIMES, 11/29/2001; CNN, 8/31/2002] It was previously controlled by the New York Port Authority, a bi-state government agency. [WALL STREET JOURNAL, 5/12/2007] Silverstein and Westfield are given the right to rebuild the structures if they are destroyed. [NEW YORKER, 5/20/2002] Silverstein Properties Not the Highest Bidder - Silverstein Properties’ bid for the WTC, at $3.22 billion, was the second highest after Vornado Realty Trust’s, at $3.25 billion. Silverstein Properties won the contract only after protracted negotiations between the Port Authority and Vornado Realty Trust failed. The privatization of the WTC has been overseen by Lewis M. Eisenberg, the chairman of the Port Authority. Eisenberg, a financier, is involved in Republican politics. [NEW YORK TIMES, 3/17/2001; FORWARD, 8/20/2004] Banks Provide Most Money for Deal - Larry Silverstein, the president of Silverstein Properties, only uses $14 million of his own money for the deal. His partners, who include real estate investors Lloyd Goldman and Joseph Cayre, put up a further $111 million, and banks provide $563 million in loans.

[AMERICAN LAWYER, 9/3/2002] After 9/11, Larry Silverstein will claim the attacks on the World Trade Center constituted two separate events, thereby entitling him to a double payout totaling over $7 billion. [DAILY TELEGRAPH, 10/9/2001; GUARDIAN, 8/18/2002] Eventually, after several years of legal wrangling, a total of $4.55 billion of insurance money will be paid out for the destruction of the WTC (see May 23, 2007). Most of this appears to go to Silverstein Properties. How much goes to Westfield America Inc. is unclear. [NEW YORK POST, 5/24/2007] Entity Tags: Vornado Realty Trust, Larry Silverstein, Joseph P.

August 2001: Moroccan Informant Warns US of Large Scale, Imminent Attack in New York In 1999, a Moroccan named Hassan Dabou infiltrated al-Qaeda for the Moroccan intelligence agency. He was sent to Afghanistan, posing as an Islamic radical on the run from the Moroccan government. While there, he was able to grow close to bin Laden. He heard bin Laden repeatedly vent his anger at the failure of the World Trade Center bombing in 1993 (see February 26, 1993). Bin Laden was “very disappointed” that the towers did not fall. Dabou heard that bin Laden had planned “something spectacular” involving “large scale operations in New York in the summer or fall of 2001.” Moroccan intelligence passed this information to US. Around this time, US intelligence is so interested that they call Dabou to Washington to report on this information in person. Dabout makes the trip in secret, but apparently his cover is blown and he is unable to go back and gather more intelligence. Dabou is still in Washington cooperating with US intelligence agents when 9/11 occurs. After 9/11 he will remain in Washington, get a new identity, and continue to work with US intelligence.

Early August 2001: Government Informant Warns Congressmen of Plan to Attack the WTC

Randy Glass. [Source: Banded Artists Productions] Randy Glass, a former con artist turned government informant, later will claim that he contacts the staff of Senator Bob Graham [D] and Representative Robert Wexler [D] at this time and warns them of a plan to attack the WTC, but his warnings are ignored. [PALM BEACH POST, 10/17/2002] Glass also tells the media at this time that his recently concluded informant work has “far greater ramifications than have so far been revealed,” and, “potentially, thousands of lives [are] at risk.” [SOUTH FLORIDA SUN-SENTINEL, 8/7/2001] Glass was a key informant in a sting operation involving ISI agents who were illegally trying to purchase sophisticated US military weaponry in return for cash and heroin. He later claims that in July 1999, one ISI agent named Rajaa Gulum Abbas pointed to the WTC and said, “Those towers are coming down.” [PALM BEACH POST, 10/17/2002] Most details apparently remain sealed. For instance Glass will claim that his sealed sentencing document dated June 15, 2001, lists threats against the WTC and Americans. [WPBF 25 (WEST PALM BEACH), 8/5/2002] Florida State Senator Ron Klein, who had dealings with Glass before 9/11, later will say he is surprised it took so many months for the US to listen to Glass: “Shame on us.” [PALM BEACH POST, 10/17/2002] Klein will recall getting a warning from Glass, though he cannot recall if it mentions the WTC specifically. He will say he was told US intelligence agencies would look into it. [WPTV 5 (WEST PALM BEACH), 10/7/2002] Senator Graham later will acknowledge that his office had contact with Glass before 9/11, and was told about a WTC attack: “I was concerned about that and a dozen other pieces of information which emanated from the summer of 2001.” However, Graham will say that he personally was unaware of Glass’s information until after 9/11. [PALM BEACH POST, 10/17/2002] In October 2002, Glass will testify under oath before a private session of the 9/11 Congressional Inquiry, stating, “I told [the inquiry] I have specific evidence, and I can document it.” [PALM BEACH POST, 10/17/2002] Entity Tags: Randy Glass, Ron Klein, Bob Graham, Pakistan Directorate for Inter-Services Intelligence, Robert Wexler, Rajaa Gulum Abbas, World Trade Center Timeline Tags: Complete 911 Timeline

August 6, 2001: Bush Receives Briefing Titled ‘Bin Laden Determined to Strike in US’

President Bush at his Crawford, Texas, ranch on August 6, 2001. Advisors wait with classified briefings. [Source: White House] President Bush receives a classified presidential daily briefing (PDB) at his Crawford, Texas ranch indicating that Osama bin Laden might be planning to hijack commercial airliners. The PDB provided to him is entitled, “Bin Laden Determined to Strike in US.” The entire briefing focuses on the possibility of terrorist attacks inside the US. [NEW YORK TIMES, 5/15/2002; NEWSWEEK, 5/27/2002] The analysts who drafted the briefing will say that they drafted it on the CIA’s initiative (see July 13, 2004), whereas in 2004 Bush will state that he requested a briefing on the topic due to threats relating to a conference in Genoa, Italy, in July 2001, where Western intelligence agencies believed Osama bin Laden was involved in a plot to crash an airplane into a building to kill Bush and other leaders (see April 13, 2004). The analysts will later explain that they saw it as an opportunity to convey that the threat of an al-Qaeda attack in the US was both current and serious. [9/11 COMMISSION, 7/24/2004, PP. 260] The existence of this briefing is kept secret, until it is leaked in May 2002, causing a storm of controversy (see May 15, 2002). While National Security Adviser Condoleezza Rice will claim the memo is only one and a half pages long, other accounts state it is 11 1/2 pages instead of the usual two or three. [NEW YORK TIMES, 5/15/2002; NEWSWEEK, 5/27/2002; DIE ZEIT (HAMBURG), 10/1/2002] A page and a half of the contents will be released on April 10, 2004; this reportedly is the full content of the briefing. [WASHINGTON POST, 4/10/2004] The briefing, as released, states as follows (note that the spelling of certain words are corrected and links have been added): Clandestine, foreign government, and media reports indicate bin Laden since 1997 has wanted to conduct terrorist attacks in the US (see December 1, 1998). Bin Laden implied in US television interviews in 1997 and 1998 that his followers would follow the example of World Trade Center bomber Ramzi Yousef and “bring the fighting to America” (see May 26, 1998). After US missile strikes on his base in Afghanistan in 1998, bin Laden told followers he wanted to retaliate in Washington, according to a -REDACTED-service (see December 21, 1998). An Egyptian Islamic Jihad (EIJ) operative told -REDACTED- service at the same time that bin Laden was planning to exploit the operative’s access to the US to mount a terrorist strike. The millennium plotting in Canada in 1999 may have been part of bin Laden’s first serious attempt to implement a terrorist strike in the US. Convicted plotter Ahmed Ressam has told the FBI that he conceived the idea to attack Los Angeles International Airport himself (see December 14, 1999), but that bin Laden lieutenant Abu Zubaida encouraged him and helped facilitate the operation. Ressam also said that in 1998 Abu Zubaida was planning his own US attack (see Late March-Early April 2001 and May 30, 2001). Ressam says bin Laden was aware of the Los Angeles operation. Although bin Laden has not succeeded, his attacks against the US Embassies in Kenya and Tanzania in 1998 (see 10:35-10:39 a.m., August 7, 1998) demonstrate that he prepares operations years in advance and is not deterred by setbacks. Bin Laden associates surveyed our embassies in Nairobi and Dar es Salaam as early as 1993 (see Late 1993-Late 1994), and some members of the Nairobi cell planning the bombings were arrested and deported in 1997. Al-Qaeda members—including some who are US citizens—have resided in or traveled to the US for years, and the group apparently maintains a support structure that could aid attacks (see January 25, 2001). Two al-Qaeda members found guilty in the conspiracy to bomb our embassies in East Africa were US citizens (see September 15, 1998), and a senior EIJ member lived in California in the mid-1990s (see November 1989 and September 10, 1998). A clandestine source said in 1998 that a bin Laden cell in New York was recruiting Muslim-American youth for attacks (see October-November 1998). “We have not been able to corroborate some of the more sensational threat reporting, such as that from a [REDACTED] service in 1998 saying that bin Laden wanted to hijack a US aircraft to gain the release of ‘Blind Sheikh’ Omar Abdul-Rahman and other US-held extremists” (see 1998, December 4, 1998, and May 23, 2001). [9/11 COMMISSION, 7/24/2004, PP. 223] According to the Washington Post, this information came from a British service. [WASHINGTON POST, 5/18/2002] Nevertheless, FBI information since that time indicates patterns of suspicious activity in this country consistent with preparations for hijackings or other types of attacks, including recent surveillance of federal buildings in New York (see May 30, 2001). The FBI is conducting approximately 70 full-field investigations throughout the US that it considers bin Laden-related (see August 6, 2001). CIA and the FBI are investigating a call to our embassy in the UAE in May saying that a group or bin Laden supporters was in the US planning attacks with explosives (see May 16-17, 2001). [9/11 COMMISSION, 7/24/2004, PP. 223] In retrospect, the briefing is remarkable for the many warnings that apparently are not included (see for instance, from the summer of 2001 prior to August alone: May 2001, June 2001, June 12, 2001, June 19, 2001, Late Summer 2001, July 2001, July 16, 2001, Late July 2001, Late July 2001, Summer 2001, June 30-July 1, 2001, July 10, 2001, and Early August 2001). According to one account, after the PDB has been given to him, Bush tells the CIA briefer, “You’ve covered your ass now” (see August 6, 2001). Incredibly, the New York Times later reports that after being given the briefing, Bush “[breaks] off from work early and [spends] most of the day fishing.” [NEW YORK TIMES, 5/25/2002] In 2002 and again in 2004, National Security Adviser Rice will incorrectly claim under oath that the briefing only contained historical information from 1998 and before (see May 16, 2002 and April 8, 2004).

Between August 6 and September 10, 2001: ’Bin Laden Determined to Strike in US’ Memo Is Not Acted Upon The 9/11 Commission will later state that after the now famous “bin Laden Determined to Strike in US” memo is given to President Bush on August 6, 2001 (see August 6, 2001), “We have found no indication of any further discussion before September 11 among the president and his top advisers of the possibility of a threat of an al-Qaeda attack in the United States.” [NEWSWEEK, 4/28/2005] 9/11 Commissioner Bob Kerrey will later state to CNN,“[B]y the way, there’s a credible case that the president’s own negligence prior to 9/11 at least in part contributed to the disaster in the first place.… [I]n the summer of 2001, the government ignored repeated warnings by the CIA, ignored, and didn’t do anything to harden our border security, didn’t do anything to harden airport country, didn’t do anything to engage local law enforcement, didn’t do anything to round up INS and consular offices and say we have to shut this down, and didn’t warn the American people. The famous presidential daily briefing on August 6, we say in the report that the briefing officers believed that there was a considerable sense of urgency and it was current. So there was a case to be made that wasn’t made.… The president says, if I had only known that 19 Islamic men would come into the United States of America and on the morning of 11 September hijack four American aircraft, fly two into the World Trade Center, one into the Pentagon, and one into an unknown Pennsylvania that crashed in Shanksville, I would have moved heaven and earth. That’s what he said. Mr. President, you don’t need to know that. This is an Islamic Jihadist movement that has been organized since the early 1990s, declared war on the United States twice, in ‘96 and ‘98. You knew they were in the United States. You were warned by the CIA. You knew in July they were inside the United States. You were told again by briefing officers in August that it was a dire threat. And what did you do?

August 21, 2001: Inmate Warns of Impending Attack in New York

Khalid al-Fawwaz, Adel Abdel Bary and Ibrahim Ediarous. [Source: Orlando Sentinel/ Bureau of Prisons] Walid Arkeh, a Jordanian serving time in a Florida prison, is interviewed by FBI agents after warning the government of an impending al-Qaeda attack. He had been in a British jail from September 2000 to July 2001, and while there had befriended three inmates, Khalid al-Fawwaz, Adel Abdel Bary, and Ibrahim Eidarous. US prosecutors charge, “The three men ran a London storefront that served as a cover for al-Qaeda operations and acted as a conduit for communications between bin Laden and his network.” [ORLANDO SENTINEL, 10/30/2002] Al-Fawwaz was bin Laden’s press agent in London, and bin Laden had called him over 200 times before al-Fawwaz was arrested in 1998. [FINANCIAL TIMES, 11/29/2001; SUNDAY TIMES (LONDON), 3/24/2002] The other two had worked in the same office as al-Fawwaz (see Early 1994-September 23, 1998). All three had been indicted as co-conspirators with bin Laden in the August 1998 US embassy bombings. Arkeh tells the FBI that he had learned from these three that “something big [is] going to happen in New York City,” and that they call the 1993 attack on the WTC “unfinished business.” Tampa FBI agents determine that he had associated with these al-Qaeda agents, but nonetheless they do not believe him. According to Arkeh, one agent responds to his “something big” warning by saying: “Is that all you have? That’s old news.” The agents fail to learn more from him. On September 9, concerned that time is running out, a fellow prisoner will try to arrange a meeting, but nothing will happen before 9/11. The Tampa FBI agents will have a second interview with him hours after the 9/11 attacks, but even long after 9/11 they will claim that he cannot be believed. On January 6, 2002, the Tampa FBI will issue a statement: “The information [was] vetted to FBI New York, the Acting Special Agent in Charge of the Tampa Division and the United States Attorney for the Middle District of Florida. All agreed the information provided by this individual was vague and unsubstantiated… Mr. Arkeh did not provide information that had any bearing on the FBI preventing September 11.” [ORLANDO SENTINEL, 1/6/2002; ORLANDO SENTINEL, 10/30/2002] However, a different group of FBI agents will interview him in May 2002 and find his information credible (see May 21-22, 2002).

August 23, 2001: Former FBI Al-Qaeda Expert Begins Job as Head of Security at the WTC John O’Neill begins his new job as head of security at the WTC. O’Neill had been the special agent in charge of the FBI’s National Security Division in New York, and was the bureau’s top expert on al-Qaeda and Osama bin Laden. [NEW YORK MAGAZINE, 12/17/2001; NEW YORKER, 1/14/2002] He’d left his job with the FBI just the day before (see August 22, 2001). His friend Jerome Hauer, who is the former head of New York’s Office of Emergency Management, had found him the job at the World Trade Center. Developer Larry Silverstein, who recently took over the lease of the WTC (see July 24, 2001), had been highly impressed with O’Neill but insisted he start in the post no later than the first week of September, when his firm Silverstein Properties is set to assume control of the buildings. O’Neill had agreed to this. [WEISS, 2003, PP. 336-338, 345-346 AND 349-351] After hearing that O’Neill has got this job, Chris Isham, a senior producer at ABC News who is a close friend, says to him, “Well, that will be an easy job. They’re not going to bomb that place again.” O’Neill replies, “Well actually they’ve always wanted to finish that job. I think they’re going to try again.” [PBS FRONTLINE, 5/31/2002] After a few days as the WTC security director, O’Neill will move into his new office on the 34th floor of the South Tower.

August 23-27, 2001: Minnesota FBI Agents ‘Absolutely Convinced’ Moussaoui Plans to Hijack Plane; They Are Undermined by FBI Headquarters

Zacarias Moussaoui’s laptop, not opened until after 9/11. [Source: FBI] In the wake of the French intelligence report (see August 22, 2001) on Zacarias Moussaoui, FBI agents in Minneapolis, Minnesota, are “in a frenzy” and “absolutely convinced he [is] planning to do something with a plane.” Agent Greg Jones tells FBI headquarters that Moussaoui might “fly something into the World Trade Center.” [NEWSWEEK, 5/20/2002; US DEPARTMENT OF JUSTICE, 11/2004, PP. 153 ] Minneapolis FBI agents become “desperate to search the computer lap top” and “conduct a more thorough search of his personal effects,” especially since Moussaoui acted as if he was hiding something important in the laptop when arrested. [TIME, 5/21/2002; TIME, 5/27/2002] As the Radical Fundamentalist Unit (RFU) at FBI headquarters has already blocked an application for a criminal warrant (see August 21, 2001), the FBI’s Minneapolis field office must apply for one under the Foreign Intelligence Surveillance Act (FISA). Minneapolis agent Harry Samit completes an application for a warrant to search Moussaoui’s belongings on August 25. To obtain the warrant, he has to show there is probable cause to believe Moussaoui is an agent of a foreign power. The memo states that Moussaoui recruited a fighter for a particular Chechen rebel group connected to al-Qaeda, so he is connected to al-Qaeda through the Chechens. However, the RFU at FBI headquarters believes that the Chechen rebels should not be described as a foreign power and that the link between the Chechens and bin Laden is not strong enough. [US DEPARTMENT OF JUSTICE, 11/2004, PP. 128-132 ; US DEPARTMENT OF JUSTICE, 3/1/2006 ] However, earlier in 2001 the FBI had received information indicating that this Chechen group and bin Laden were planning to attack US interests (see Before April 13, 2001). Minneapolis FBI agent Coleen Rowley later sums up how the Minneapolis agents feel at this point, when she says FBI headquarters “almost inexplicably, throw up roadblocks” and undermine their efforts. Headquarters personnel bring up “almost ridiculous questions in their apparent efforts to undermine the probable cause.” One of Jones’ e-mails to FBI headquarters says they are “setting this up for failure.” That turns out to be correct.

No explanation has been given for this measure.” [INDEPENDENT, 9/17/2001] Newsday claims that around the same time, security personnel at the WTC begin working extra-long shifts because of numerous phone threats. However, on September 6, bomb-sniffing dogs are abruptly removed. Security further drops right before 9/11.

He calls it “an attack that will change the world.” After a month of badgering his prison guards, he is finally able to call the White House 14 times in the days before the attack. He then tries to send a fax to President Bush, but is denied permission hours before the 9/11 attacks. German police later confirm the calls.

The company had acquired the lease to operate the Twin Towers from the New York Port Authority in late July (see July 24, 2001). It has already begun managing the facility with its own executives. Selected Port Authority employees, including Alan Reiss, the director of the World Trade Center, have been assisting the firm during a three-month transition period.

Between September 3, 2001 and September 7, 2001: WTC Structural Engineer Says Trade Center Designed for 707 Crashing Into It

Leslie Robertson. [Source: Publicity photo] Leslie Robertson, one of the two original structural engineers for the World Trade Center, is asked at a conference in Frankfurt, Germany what he had done to protect the Twin Towers from terrorist attacks. He replies, “I designed it for a 707 to smash into it,” though does not elaborate further. [CHICAGO TRIBUNE, 9/12/2001; KNIGHT RIDDER, 9/12/2001] The Twin Towers were in fact the first structures outside the military and nuclear industries designed to resist the impact of a jet airplane. [ROBERTSON, 3/2002; FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 1-17] The Boeing 707 was the largest in use when the towers were designed. Robertson conducted a study in late 1964, to calculate the effect of a 707 weighing 263,000 pounds and traveling at 180 mph crashing into one of the towers. He concluded that the tower would remain standing. However, no official report of his study has ever surfaced publicly. [GLANZ AND LIPTON, 2004, PP. 138-139, 366] A previous analysis, carried out early in 1964, calculated that the towers would handle the impact of a 707 traveling at 600 mph without collapsing (see February 27, 1993). In 2002, though, Robertson will write, “To the best of our knowledge, little was known about the effects of a fire from such an aircraft, and no designs were prepared for that circumstance.” [ROBERTSON, 3/2002] The planes that hit the WTC on 9/11 are 767s, which are almost 20 percent heavier than 707s.

September 4, 2001: Secret Embedded Messages Help Show Milan Al-Qaeda Have 9/11 Foreknowledge At least one member of the al-Qaeda cell in Milan, Italy, apparently uses steganography, a method of encoding messages within computerized photographs. In Milan’s Via Quaranta mosque in Milan, frequented by Egyptian al-Qaeda operative Mahmoud Es Sayed, pictures of the World Trade Center that have steganographic messages in them are saved on a computer. A number of other pictures of world leaders and pornography are also manipulated in a similar manner. These pictures will not be discovered until months after 9/11, but they help suggest that some in the Milan cell had foreknowledge of the 9/11 plot. Es Sayed had been wiretapped on previous occasions, and was heard making comments suggesting he had such foreknowledge (see August 12, 2000) (see January 24, 2001).

They won’t be standing there next week.” At the time, nothing is thought of it, but on September 13, the FBI will interview all the people in the classroom and confirm the event. The FBI later places the boy’s family under surveillance but apparently is unable to find a connection to the 9/11 plot. An MSNBC reporter later sets out to disprove this “urban myth,” but to his surprise, finds all the details of the story are confirmed. The fact that the family members are recent immigrants from Pakistan might mean the information came from Pakistan.

September 10, 2001: New WTC Security Director Warns of Danger of ‘Something Big’ John O’Neill, who is later described by the New Yorker magazine as the FBI’s “most committed tracker of Osama bin Laden and his al-Qaeda network of terrorists,” recently retired from the bureau and started a new job as director of security at the World Trade Center (see August 23, 2001). [NEW YORKER, 1/14/2002] On this day he meets up with his old friend Raymond Powers, the former New York Police Department chief of operations, to discuss security procedures. Their conversation turns to Osama bin Laden. According to journalist and author Murray Weiss, “just as he had reiterated since 1995 to any official in Washington who would listen, O’Neill said he was sure bin Laden would attack on American soil, and expected him to target the Twin Towers again.” He says to Powers, “It’s going to happen, and it looks like something big is brewing.” [WEISS, 2003, PP. 355 AND 359-360] Later on, O’Neill goes out in the evening with his friends Robert Tucker and Jerome Hauer. Again, he starts discussing bin Laden. He tells his friends, “We’re due. And we’re due for something big.” He says, “Some things have happened in Afghanistan. I don’t like the way things are lining up in Afghanistan.” This is probably a reference to the assassination of Afghan leader Ahmed Shah Massoud the previous day (see September 9, 2001). He adds, “I sense a shift, and I think things are going to happen.” Asked when, he replies, “I don’t know, but soon.” [NEW YORKER, 1/14/2002; PBS, 10/3/2002] O’Neill will be in his office on the 34th floor of the South Tower the following morning when the first attack occurs, and dies when the WTC collapses.

September 10, 2001: Atta Allegedly Visits the WTC to Enter Coordinates Into GPS Device; One Report Claims Mistaken Identity Credit card receipts later discovered by the FBI apparently show that alleged lead hijacker Mohamed Atta is in Manhattan on this day. According to FBI agents, he visits the observation deck on the 107th floor of the south WTC tower. CNN will report, “Officials speculate Atta may have been in New York… to program the towers’ location into a global positioning system.” A global positioning system (GPS) uses satellite technology to pinpoint any location on Earth. According to the FBI, Atta bought himself such a device, costing about $500, by mail order. [ABC NEWS, 5/22/2002; CNN, 5/22/2002] Investigators will reportedly consider this trip necessary, “because they believe the hijackers were too inexperienced to handle the jumbo jets without help.” [NEW YORK DAILY NEWS, 5/22/2002] BBC reporter Jane Corbin points out that Atta was also witnessed at Boston’s Logan Airport the previous morning (see September 9, 2001), where he could have entered start-point co-ordinates for his 9/11 flight into the GPS device. [CORBIN, 2003, PP. 230] However, there is no mention of Atta’s New York visit in the 9/11 Commission Report. According to FBI Director Robert Mueller, Atta spent the previous night at the Milner Hotel in Boston, and then shortly after noon on this day is in Boston where he picks up Abdulaziz Alomari and drives to Portland, Maine. [US CONGRESS, 9/26/2002] The 200-mile journey from Boston to New York takes approximately four hours by car. [MIT, 5/25/2006] So if Mueller’s account is correct, it seems difficult to comprehend Atta having time to travel to New York, go up the WTC, make purchases on his credit card, and then return to Boston, all in the space of one morning. An article in the New York Post will in fact claim that the person in Manhattan was “a distinguished renal and gene specialist at Johns Hopkins University Hospital” in Baltimore, Maryland. This man, who is also called Mohamed Atta, happened to have visited New York in the days before 9/11, “for a whirlwind weekend with his new bride.” The article claims that it had erroneously been reported that alleged hijacker Mohamed Atta “was casing the Twin Towers days before Sept. 11—even after the FBI concluded it was just the kidney doctor, who had planned to take his wife to Windows on the World for dinner in the North Tower.” [NEW YORK POST, 5/28/2002] Entity Tags: World Trade Center, Mohamed Atta Timeline Tags: Complete 911 Timeline, 9/11 Timeline

According to author Lynn Spencer, when Trey Murphy—a former US Marine who is now a weapons controller at NEADS—first sees the television footage on September 11 showing that a plane has hit the WTC, the news will bring to mind one of his briefings: “What if a terrorist flies an airplane with a weapon of mass destruction into the World Trade Center? It had always been one of the military’s big fears.… [T]he image on the [television] screen certainly reminded him of his briefing.” [SPENCER, 2008, PP. 179] It is also later reported that, in the two years prior to 9/11, NORAD conducts exercises simulating terrorists crashing hijacked aircraft into targets that include the WTC (see Between September 1999 and September 10, 2001).

She later recalls that the men—one who appears Middle Eastern, the other Caucasian—upgrade from coach to first class, and then sit “on the left side of the plane, seats 3A and 3B,” near the cockpit door.

Odigo, one of the world’s largest instant messaging companies, has its headquarters two blocks from the WTC. The Odigo Research and Development offices where the warnings were received are located in Herzliyya, a suburb of Tel Aviv.

The notes ended with an anti-Semitic slur. ‘The messages said something big was going to happen in a certain amount of time, and it did—almost to the minute,’ said Alex Diamandis, vice president of sales for the high-tech company… He said the employees did not know the person who sent the message, but they traced it to a computer address and have given that information to the FBI.” [WASHINGTON POST, 10/4/2001] Odigo gave the FBI the Internet address of the message’s sender so the name of the sender could be found.

(8:46 a.m.) September 11, 2001: Janitor Hears Explosion from WTC Basement

William Rodriguez [Source: Publicity photo] According to a WTC janitor, there is an explosion in the basement of the North Tower just before the plane hits up above. William Rodriguez has worked at the World Trade Center for 20 years, including the time of the 1993 bombing, and is responsible for cleaning three stairwells in the North Tower. He is talking to his supervisor in an office in the B-1 level in the basement when, he says, “I heard this massive explosion below, on level B-2 or 3.” He says, “The floor vibrated. We were all thrown upwards, then everyone in the office started screaming.” Then, “seconds later, there was another explosion way above, which made the building sway from side to side. And this, we later discovered, was the first plane hitting the North Tower on the 90th floor.” A man then runs into the office, shouting, “Explosion! Explosion!” The man, Felipe David, had been standing in front of a nearby lift when a fireball had burst from the lift shaft, severely burning him. Rodriguez will later question, “Now you tell me how an explosion from a jet liner could have burnt a man 90 floors down within seconds of impact?” The National Institute of Standards and Technology (NIST) will suggest that the basement explosion Rodriguez heard might have been caused by a fireball traveling from the aircraft down the central lift shaft. However, some time after hearing it, Rodriguez rescues two people trapped in a lift. He will therefore doubt NIST’s claim, saying that if it were true, “Why were the two people [I] rescued from the lift not burnt to death?” [NEW YORK MAGAZINE, 3/20/2006; WESTERN MORNING NEWS, 12/2/2006; HERALD (GLASGOW), 2/16/2007; ARGUS (BRIGHTON), 2/26/2007] Rodriguez also claims to have witnessed alleged hijacker Mohand Alshehri in the World Trade Center in June 2001 (see June 2001).

The hole caused by the Flight 11 crash. [Source: Reuters] Flight 11 slams into the WTC North Tower (Building 1). Seismic records pinpoint the crash at 26 seconds after 8:46 a.m. [CNN, 9/12/2001; NEW YORK TIMES, 9/12/2001; NORTH AMERICAN AEROSPACE DEFENSE COMMAND, 9/18/2001; USA TODAY, 12/20/2001; FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 1-10; USA TODAY, 8/13/2002; ASSOCIATED PRESS, 8/21/2002; NEWSDAY, 9/10/2002; NEW YORK TIMES, 9/11/2002] The NIST report states the crash time to be 8:46:30. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 19 ] The 9/11 Commission Report states the crash time to be 8:46:40. [9/11 COMMISSION, 7/24/2004, PP. 7] Investigators believe the plane still has about 10,000 gallons of fuel (see 8:57 a.m. September 11, 2001). [NEW YORK TIMES, 9/11/2002] The plane strikes the 93rd through 99th floors in the 110-story building. No one above the crash line survives; approximately 1,360 people die. Below the crash line, approximately 72 die and more than 4,000 survive. Both towers are slightly less than half full at the time of the attack, with between 5,000 to 7,000 people in each tower. This number is lower than expected. Many office workers have not yet shown up to work, and tourists to the observation deck opening at 9:30 A.M. have yet to arrive. [USA TODAY, 12/20/2001; NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 20-22 ] The impact severs some columns on the north side of the North Tower. Each tower is designed as a “tube-in-tube” structure and the steel columns which support its weight are arranged around the perimeter and in the core. The plane, which weighs 283,600 lb and is traveling at an estimated speed of around 430 mph (see October 2002-October 2005), severs 35 of the building’s 236 perimeter columns and damages another two. The damage to the South Tower’s perimeter will be similar (see 9:03 a.m. September 11, 2001). [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 5-9, 20, 22 ] The perimeter columns bear about half of the tower’s weight, so this damage reduces its ability to bear gravity loads by about 7.5 percent. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 6 ] The actual damage to the 47 core columns is not known, as there are no photographs or videos of it, but there will be much speculation about this after 9/11. It will be suggested that some parts of the aircraft may have damaged the core even after crashing through the exterior wall. According to the National Institute of Standards and Technology (NIST): “Moving at 500 mph, an engine broke any exterior column it hit. If the engine missed the floor slab, the majority of the engine core remained intact and had enough residual momentum to sever a core column upon direct impact.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 107 ] According to NIST’s base case computer model, three of the core columns are severed and another ten suffer some damage. [NATIONAL INSTITUTE OF STANDARDS & TECHNOLOGY, 9/2005, PP. 189 ] If this is accurate, it means that the impact damage to the core reduces the Tower’s strength by another approximately 7.5 percent, meaning that the building loses about 15 percent of its strength in total. This damage will be cited after 9/11 by NIST and others researchers as an event contributing to the building’s collapse (see October 23, 2002 and October 19, 2004). In addition, some of the fireproofing on the steel columns and trusses may be dislodged. The original fireproofing on the fire floors was mostly Blazeshield DC/F, but some of the fireproofing on the flooring has recently been upgraded to Blazeshield II, which is about 20 percent denser and 20 percent more adhesive. [NATIONAL INSTITUTE OF STANDARDS & TECHNOLOGY, 9/2005, PP. XXXVI, 83 ] Photographs and videos of the towers will not show the state of fireproofing inside the buildings, but NIST will estimate the damage to it using a computer model. Its severe case model (see (October 2002-October 2005)) will predict that 43 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 60,000 ft2 of floor area, the equivalent of about one and a half floors. NIST will say that the loss of fireproofing is a major cause of the collapse (see April 5, 2005), but only performs 15 tests on fireproofing samples (see October 26, 2005). [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 23 ] According to NIST, more fireproofing is stripped from the South Tower (see 9:03 a.m. September 11, 2001).

[Source: Yvonne Vermillion/ MagicGraphix.com] When Flight 11 hits the WTC at 8:46 a.m., President Bush’s motorcade is crossing the John Ringling Causeway on the way to Booker Elementary School from the Colony Beach and Tennis Resort on Longboat Key. [WASHINGTON TIMES, 10/8/2002] White House Press Secretary Ari Fleischer is riding in a motorcade van, along with adviser Karl Rove and Mike Morell, the CIA’s White House briefer. Shortly after the attack, Fleischer is talking on his cell phone, when he blurts out: “Oh, my God, I don’t believe it. A plane just hit the World Trade Center.” (The person with whom he is speaking remains unknown.) Fleischer is told he will be needed on arrival at the school to discuss reports of the crash. [CHRISTIAN SCIENCE MONITOR, 9/17/2001; ALBUQUERQUE TRIBUNE, 9/10/2002; TENET, 2007, PP. 165-166] This call takes place “just minutes” after the first news reports of the attack according to one account, or “just before 9:00 a.m.” according to another. [MSNBC, 10/29/2002; KESSLER, 2004, PP. 138] Fleischer asks Morell if he knows anything about a small plane hitting the World Trade Center. Morell doesn’t, and immediately calls the CIA Operations Center. He is informed that the plane that hit the WTC wasn’t small. [KESSLER, 2003, PP. 193; TENET, 2007, PP. 165-166] Congressman Dan Miller also says he is told about the crash just before meeting Bush at Booker Elementary School at 8:55 a.m. [SARASOTA MAGAZINE, 9/19/2001] Some reporters waiting for Bush to arrive also learn of the crash just minutes after it happens. [CBS NEWS, 9/11/2002] It would make sense that the president would be told about the crash immediately, at the same time that others hear about it. His limousine has “Five small black antennae sprouted from the lid of the trunk in order to give Bush the best mobile communications money could buy.” [SAMMON, 2002, PP. 38] Sarasota Magazine in fact claims that Bush is on Highway 301, just north of Main Street, on his way to the school, when he receives a phone call informing him a plane has crashed in New York City. [SARASOTA MAGAZINE, 9/19/2001] Yet the official story remains that he is not told about the crash until he arrives at the school (see (Between 8:55 a.m. and 9:00 a.m.) September 11, 2001). Author James Bamford comments, “Despite having a secure STU-III phone next to him in the presidential limousine and an entire national security staff at the White House, it appears that the president of the United States knew less than tens of millions of other people in every part of the country who were watching the attack as it unfolded.” [BAMFORD, 2004, PP. 17] Entity Tags: Michael J.

(8:47 a.m.-9:50 a.m.) September 11, 2001: Engineer Finds Major Damage in Basement and Lobby of North Tower

Mike Pecoraro. [Source: Chief Engineer] Mike Pecoraro, an engineer who is part of the crew that services the WTC complex, is at work in the mechanical shop in the second subbasement of the north WTC tower when it is hit. When the room he is in starts filling with white smoke and he can smell kerosene (jet fuel), he heads up stairs with a co-worker towards a small machine shop on the C level. Yet, he says, “There was nothing there but rubble. We’re talking about a 50 ton hydraulic press—gone!” He then heads for the parking garage, yet finds that “there were no walls, there was rubble on the floor, and you can’t see anything.” He ascends to the B level where he sees a 300-pound steel and concrete fire door, which is lying on the floor, wrinkled up “like a piece of aluminum foil.” Pecoraro recalls seeing similar things at the Center when it was bombed in 1993 and is therefore convinced that a bomb has gone off this time. When he makes it into the main lobby, he sees massive damage: “The whole lobby was soot and black, elevator doors were missing. The marble was missing off some of the walls. 20-foot section of marble, 20 by 10 foot sections of marble, gone from the walls.… Broken glass everywhere, the revolving doors were all broken and their glass was gone.” Pecoraro says he only later hears that “jet fuel actually came down the elevator shaft, blew off all the (elevator) doors and flames rolled through the lobby. That explained all the burnt people and why everything was sooted in the lobby.” He makes it out of the North Tower before it collapses.

This homemaker, who has given only her first name Maria, is called by a neighbor shortly after the first plane has hit the WTC and is told about the impact. She has a view of the WTC from her apartment building so she gets her binoculars and watches the disaster. However, she also notices three young men kneeling on the roof of a white van in the parking lot of her apartment building. Maria will later recall, “They seemed to be taking a movie.” They are taking video or photos of themselves with the WTC burning in the background. But what strikes Maria is their expressions: “They were like happy, you know… They didn’t look shocked to me. I thought it was very strange.” She writes down the license plate number of the van and calls the police. [ABC NEWS, 6/21/2002] Apparently the men leave the area a few minutes after the first attack is over. [COUNTERPUNCH, 2/7/2007] An FBI lookout bulletin for the van will be issued later in the day (see 3:31 p.m. September 11, 2001) and the three men (plus two more discovered with them) will be detained (see 3:56 p.m. September 11, 2001).

8:47 a.m.-10:28 a.m. September 11, 2001: Hundreds Die in WTC Elevators, as Elevator Mechanics Flee During the 9/11 catastrophe, around 200 people die in the WTC’s elevators without getting help from elevator mechanics, according to an in-depth study later performed by USA Today. Some of the victims are burned by the initial explosion, some die as the elevator cars plummet when their cables are severed, and some are stuck and perish in the collapse. USA Today will say it “could not locate any professional rescues of people stuck in elevators. The Fire Department of New York and the Port Authority also could not cite successful rescues.” After the North Tower is hit, most of the WTC’s 83 elevator mechanics gather in the lobby of the South Tower, but when the second plane hits, they evacuate. In contrast, a passing elevator mechanic from another company runs into the WTC and dies trying to free trapped passengers. USA Today will comment: “When the World Trade Center was bombed in 1993, Otis Elevator’s mechanics led the rescue of 500 people trapped in elevators. Some mechanics were dropped onto the roofs of the Twin Towers by helicopter. Others, carrying 50-pound oxygen tanks on their backs, climbed through smoke to machine rooms high in the towers. On Sept. 11, the elevator mechanics—many of the same men involved in the rescues in 1993—left the buildings after the second jet struck, nearly an hour before the first building collapsed.” Although ACE Elevator, the local company which won the WTC contract from Otis in 1994, will say it was acting in accordance with procedure, USA Today will note: “The departure of elevator mechanics from a disaster site is unusual. The industry takes pride in rescues. In the Oklahoma City bombing in 1995, elevator mechanics worked closely with the firefighters making rescues.” Robert Caporale, editor of Elevator World will say, “Nobody knows the insides of a high-rise like an elevator mechanic. They act as guides for firefighters, in addition to working on elevators.” The Port Authority will also say that their departure was in conflict with the emergency plan. “There was no situation in which the mechanics were advised or instructed to leave on their own.” [USA TODAY, 12/19/2001; USA TODAY, 9/4/2002] Entity Tags: World Trade Center, ACE Elevator, New York Port Authority, Robert Caporale Timeline Tags: Complete 911 Timeline, 9/11 Timeline

Shortly After 8:46 a.m. September 11, 2001: Newark Airport Controllers Contact Other FAA Facilities about Burning WTC

Bob Varcadipane. [Source: NBC News] At the air traffic control tower at Newark International Airport in New Jersey, controllers see the smoke coming from the World Trade Center in the distance and start calling other FAA facilities in the area about this. Controller Rick Tepper looks out the window of the tower across the Hudson River at New York City, and sees the huge cloud of smoke coming from the North Tower, which Flight 11 has crashed into it. He points this out to fellow controller Greg Callahan. In his office at the tower, Bob Varcadipane, the supervisor there, starts receiving a flood of phone calls reporting that a small aircraft has hit the WTC. According to author Lynn Spencer, “The assumption is that only a small plane could have gone so badly off course.” The Newark tower controllers start calling the towers at JFK, La Guardia, and Teterboro Airports, along with other air traffic control facilities in the area, to see if any of them has lost an aircraft. But none say they have; they have not yet been informed of the crash and are shocked at what they see when told to look out their windows at the burning WTC. Varcadipane calls the FAA’s New York Center to find out if they know whose plane hit the Twin Towers. He is told: “No, but Boston Center lost an airplane. They lost an American 767.” Varcadipane wonders if this 767 is the plane that hit the WTC, and says back: “I have a burning building and you have a missing airplane. This is very coincidental.” According to NBC: “a horrific realization dawns on controllers. American Flight 11, still missing from radar, finally has been found.” Word of the plane’s fate subsequently “quickly travels throughout the air traffic control world.” [MSNBC, 9/11/2002; SPENCER, 2008, PP. 41-42] However, the FAA’s Indianapolis Center, which handles Flight 77, will reportedly not learn of the first hijackings until around 9:20 a.m. (see (9:20 a.m.-9:21 a.m.) September 11, 2001).

And it appears to have crashed into—I don’t know which tower it is—but it hit directly in the middle of one of the World Trade Center towers. It was a jet, maybe a two-engine jet, maybe a 737… a large passenger commercial jet… It was teetering back and forth, wing-tip to wing-tip, and it looks like it has crashed into—probably, twenty stories from the top of the World Trade Center—maybe the eightieth to eighty-fifth floor.

Then, when he reaches the 33rd floor he hears what sounds like heavy equipment being dragged across the floor of the level above. He finds this puzzling, he later says, because the 34th floor is supposed to be empty and has been off limits for weeks due to a construction project. After he reaches the 39th floor, Rodriguez is ordered to turn back by the firefighters with him. He then hears the sound of the second plane hitting the WTC, at 9:03 a.m. Rodriguez also claims he heard an explosion from the North Tower’s basement just seconds before it was hit at 8:46 a.m. (see (8:46 a.m.) September 11, 2001).

They are interrupted when CIA bodyguards converge on the table to hand Tenet a cell phone. Tenet is told that the WTC has been attacked by an airplane. Boren later says, “I was struck by the fact that [the messenger] used the word ‘attacked.’” Tenet then hands the cell phone back to an aide and says to Boren, “You know, this has bin Laden’s fingerprints all over it.” “‘He was very collected,’ Boren recalls. ‘He said he would be at the CIA in 15 minutes, what people he needed in the room and what he needed to talk about.’” [USA TODAY, 9/24/2001; ABC NEWS, 9/14/2002] According to other accounts, Tenet responds to the caller, “They steered the plane directly into the building?” Tenet then says to Boren, “That looks like bin Laden.” Tenet muses aloud, “I wonder if this has something to do with the guy [Zacarias Moussaoui] who trained for a pilot’s license.” (Moussaoui had been arrested several weeks earlier.) [ST. PAUL PIONEER PRESS, 5/29/2002; STERN, 8/13/2003] According to another account, Tenet pauses while on the phone to tell Boren, “The World Trade Center has been hit. We’re pretty sure it wasn’t an accident. It looks like a terrorist act,” then returns to the phone to identify who should be summoned to the CIA situation room. [TIME, 9/14/2001] Tenet later tells author Ronald Kessler, “There was no doubt that al-Qaeda was going to come here eventually, and that something spectacular was planned. I knew immediately who it was [behind the attack].” [KESSLER, 2003, PP. 196] In his own 2007 book, Tenet will largely confirm the above accounts. He will add, “Most people, I understand, assumed that the first crash was a tragic accident. It took the second plane hitting the second tower to show them that something far worse was going on. That wasn’t the case for me. We had been living too intimately with the possibility of a terrorist attack on the United States. I instantly thought that this had to be al-Qaeda.” He also mentions thinking aloud about Moussaoui.

8:57 a.m. September 11, 2001: Jet Fuel in North Tower Burns Up The jet fuel that spilled from Flight 11 when it hit the North Tower (see 8:46 a.m. September 11, 2001) has mostly burned up by this time. The National Institute of Standards and Technology (NIST), which investigates the collapses, will say “The initial jet fuel fires themselves lasted at most a few minutes.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 183 ] Engineering professor Forman Williams will say the jet fuel “burned for maybe 10 minutes.” [POPULAR MECHANICS, 3/2005] Flight 11, a Boeing 767, had a fuel capacity of 23,980 gallons, but was only carrying about 10,000 gallons when it hit the WTC. NIST will estimate that less than 1,500 gallons were consumed in a fireball inside the tower and a comparable amount was consumed in the fireballs outside the building. Therefore, approximately 7,000 gallons splashed onto the office furnishings and started fires on various floors. However, after the jet fuel is used up, office fires burn until the building collapses. NIST will calculate that there were about four pounds per square foot of combustibles in the office space, or about 60 tons per floor. Offices in the WTC actually have fewer combustibles than some other similar spaces due to the small number of interior walls and limited bookshelf space. NIST will later find that only three of sixteen perimeter columns it recovers reached a temperature of 250°C and neither of the two core columns it retrieves reached this temperature. NIST will also find that none of the samples it acquires reaches a temperature above 600°C (see August 27, 2003). Although steel does not melt until its temperature is about 1,600°C, it may begin to lose significant strength at over 500°C. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 20, 29, 24, 77 ] The jet fuel will also burn up in the South Tower about 10 minutes after it is hit (see 9:13 a.m. September 11, 2001).

(8:57 a.m.) September 11, 2001: Fire Department Advice to Evacuate WTC Tower Fails to Reach People Inside

People inside the World Trade Center flee down a stairway. [Source: Shannon Stapleton] By 8:57 a.m., fire department commanders at WTC Tower One advise Port Authority police and building personnel to evacuate Tower Two. According to the 9/11 Commission, the reason for this is not concern of a possible second plane, but because the fire chiefs judge the impact of the plane into the North Tower to have made the entire WTC complex unsafe. However, there is no evidence that this advice is communicated effectively to the building personnel in Tower Two. When an announcement is made to evacuate at 9:02 a.m. (one minute before the building is hit), it does not direct everyone to evacuate, and advises only that everyone may wish to start an orderly evacuation if warranted by conditions on their floor.

At 9:02, he repeats this, saying, “Evacuate all buildings in the complex. You copy? All buildings in the complex.” However, his order is given over WTC police radio channel W, which cannot be heard by the deputy fire safety director in the South Tower.

Before 9:00 a.m. September 11, 2001: Army Base Outside New York Prepares for Terrorist Attack Exercise Staff at Fort Monmouth, an Army base in New Jersey located about 50 miles south of New York City, is preparing to hold a “disaster drill” to test emergency response capabilities to a fake chemical attack. The exercise, called Timely Alert II, is to involve various law enforcement agencies and emergency personnel, including Fort Monmouth firefighters and members of the New Jersey State Police. Personnel are to be deployed and measures taken as in a real emergency. A notice has been sent out, warning that anyone not conducting official business will be turned away from Fort Monmouth during the exercise. Soon after 9 a.m., the exercise director tells a group of participating volunteers that a hijacked plane has crashed into the World Trade Center. The participants pretend to be upset, believing this is just part of the simulation. When they see the live televised footage of the WTC attacks, some people at the base think it is an elaborate training video to accompany the exercise. One worker tells a fire department training officer: “You really outdid yourself this time.” Interestingly, the follow-up exercise held in July 2002 (Timely Alert III) does incorporate simulated television news reports to give participants the impression that the emergency is real. And in the first Timely Alert exercise, held on the base in January 2001, a call had come through of a supposed “real” bomb situation, but this “fortunately turned out to be a report related to a training aid being used during the exercise.” On 9/11, Fort Monmouth is geared to go into high-alert status as part of Timely Alert II. The exercise is called off once the base is alerted to the real attacks. [MONMOUTH MESSAGE, 2/9/2001; HUB, 9/21/2001; MONMOUTH MESSAGE, 9/21/2001; ASBURY PARK PRESS, 7/24/2002; MONMOUTH MESSAGE, 8/23/2002; US DEPARTMENT OF THE ARMY, 7/26/2003 ; MONMOUTH MESSAGE, 9/12/2003] Fort Monmouth is home to various Army, Defense Department, and other government agencies. The largest of these is the US Army’s Communications-Electronics Command (CECOM). CECOM serves to “develop, acquire, field, and sustain superior information technologies and integrated systems for America’s warfighters.” It is tasked with the “critical role of command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR).” [COMMUNICATIONS-ELECTRONICS COMMAND, 4/17/2002; US DEPARTMENT OF THE ARMY, 1/2003 ; GLOBALSECURITY (.ORG), 2/12/2006] Fort Monmouth services also directly assist in the emergency response later in the day. Its fire department deploys to Atlantic Highlands to assist passengers coming from Manhattan by ferry, and members of its Patterson Army Health Clinic are also sent out to help. Teams of CECOM experts from the base are later deployed to ground zero in New York with equipment capable of locating cellular phone transmissions within the ruins of the collapsed World Trade Center. Its explosive ordnance company is also deployed to assist authorities should they come across anything they think might be explosives, while digging through the debris in search of victims.

September 11, 2001: More Than $100 Million Rushed from WTC Data recovery experts later looking at 32 hard drives salvaged from the 9/11 attacks discover a surge in credit card transactions from the World Trade Center in the hours before and during the attacks. Unusually large sums of money are rushed through computers even as the disaster unfolds. Investigators later say: “There is a suspicion that some people had advance knowledge of the approximate time of the plane crashes in order to move out amounts exceeding $100 million. They thought that the records of their transactions could not be traced after the mainframes were destroyed.” The data recovery effort is led by the German company Convar.

(9:00 a.m.) September 11, 2001: WTC South Tower Announcement: OK to Return to Offices A public announcement is broadcast inside the WTC Tower Two (the South Tower, which has yet to be hit), saying that the building is secure and people can return to their offices. [NEW YORK TIMES, 9/11/2002] Such announcements continue until a few minutes before the building is hit, and “may [lead] to the deaths of hundreds of people.” No one knows exactly what is said (though many later recall the phrase “the building is secure”), or who gives the authority to say it. [USA TODAY, 9/2/2002] Additionally, security agents inside the building repeat similar messages to individuals in the tower. For instance, one survivor recounts hearing, “Our building is secure. You can go back to your floor. If you’re a little winded, you can get a drink of water or coffee in the cafeteria.” [NEW YORK TIMES, 9/13/2001] Another survivor recalls an escaping crowd actually running over a man with a bullhorn encouraging them to return to their desks. [NEWSDAY, 9/12/2001] Businessman Steve Miller recalls hearing a voice say over the building’s loudspeaker something similar to: “There’s a fire in Tower One. Tower Two in unaffected. If you want to leave, you can leave. If you want to return to your office, it’s okay.” [WASHINGTON POST, 9/16/2001] British visitor Mike Shillaker recalls, “As we got to around floor 50, a message came over the [loudspeaker], telling us that there was an isolated fire in Tower One, and we did not need to evacuate Tower Two. Again, thank god we continued down, others didn’t.” [BBC, 9/1/2002] Despite messages to the contrary, about two-thirds of the tower’s occupants evacuate during the 17 minutes between the attacks.

(9:03 a.m.) September 11, 2001: WTC Building 7 Evacuated According to a soldier at the scene, WTC Building 7 is evacuated before the second tower is hit. [FORT DETRICK STANDARD, 10/18/2001] The National Institute of Standards and Technology (NIST) states, “As the second aircraft struck WTC 2, a decision was made to evacuate WTC 7.” This would be just after the Port Authority Police Department called for the evacuation of the entire WTC complex (see 8:59 a.m.-9:02 a.m. September 11, 2001). But by this time, “many WTC 7 occupants [have] already left the building and others [have] begun a self-evacuation of the building.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 109 ] All individuals in the Secret Service’s New York field office, located in WTC 7, were ordered to evacuate after the first attack, and they are in the process of doing so when the second plane hits the South Tower. [PCCW NEWSLETTER, 3/2006] The Secret Service has a Stinger missile secretly stored in the WTC, to be used to protect the president if there were an attack on the city when he visits it. [WEISS, 2003, PP. 379] Presumably, this missile is abandoned with the evacuation.

Flight 175 hits the WTC South Tower. The picture was taken from a traffic helicopter. [Source: WABC 7/ Salient Stills] Flight 175 hits the South Tower of the World Trade Center (Tower Two). Seismic records pinpoint the time at six seconds before 9:03 a.m. (rounded to 9:03 a.m.). [NEW YORK TIMES, 9/12/2001; CNN, 9/12/2001; CNN, 9/17/2001; NORTH AMERICAN AEROSPACE DEFENSE COMMAND, 9/18/2001; USA TODAY, 12/20/2001; FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 1-10; ASSOCIATED PRESS, 8/21/2002; USA TODAY, 9/2/2002; NEW YORK TIMES, 9/11/2002] According to the NIST report, the crash time is 9:02:59. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 38 ] According to the 9/11 Commission Report, the crash time is 9:03:11. [9/11 COMMISSION, 7/24/2004, PP. 8] Millions watch the crash live on television. The plane strikes the 77th through 85th floors in the 110-story building. Approximately 100 people are killed or injured in the initial impact; 600 people in the tower eventually die. The death toll is far lower than in the North Tower because about two-thirds of the South Tower’s occupants have evacuated the building in the 17 minutes since the first tower was struck. [USA TODAY, 12/20/2001; NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 5-9, 41 ] The combined death toll from the two towers is estimated at 2,819, not including the hijackers. [ASSOCIATED PRESS, 8/21/2002] The impact severs some columns on the south side of the South Tower. Each of the Twin Towers is designed as a “tube-in-tube” structure and the steel columns which support its weight are arranged around the perimeter and in the core. The plane, which is traveling at an estimated speed of around 500 mph (see October 2002-October 2005), severs 33 of the building’s 236 perimeter columns and damages another one. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 39 ] The perimeter columns bear about half of the tower’s weight, so the damage to them reduces the tower’s ability to bear gravity loads by about 7.1 percent. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 6 ] The actual damage to the 47 core columns is not known, as there are no photographs or videos of it, but there will be much speculation about this after 9/11. It will be suggested that some parts of the aircraft may be able to damage the core even after crashing through the exterior wall (see 8:46 a.m. September 11, 2001). [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 107 ] According to NIST’s base case model, five of the core columns are severed and another five suffer some damage. [NATIONAL INSTITUTE OF STANDARDS & TECHNOLOGY, 9/2005, PP. 235 ] This may reduce the tower’s ability to bear loads by a further approximately 8 percent, meaning that the aircraft impact accounted for a loss of about 15 percent of the building’s strength. This damage will be cited as an event contributing to the building’s collapse after 9/11 (see October 23, 2002 and October 19, 2004). NIST’s base case estimate of damage to the North Tower’s core will be similar, even though the aircraft impact there was dissimilar (see 8:46 a.m. September 11, 2001). Flight 11 hit the North Tower’s core head on, whereas Flight 175 only hits the corner of the South Tower’s core. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 20-23, 38-41 ] In addition, some of the fireproofing on the steel columns and trusses may be dislodged (see 8:46 a.m. September 11, 2001). [NATIONAL INSTITUTE OF STANDARDS & TECHNOLOGY, 9/2005, PP. XXXVI, 83 ] Photographs and videos of the towers will not show the state of fireproofing inside the buildings, but the National Institute of Standards and Technology (NIST) will try to estimate the damage to fireproofing using a series of computer models. Its severe case model (see (October 2002-October 2005)) will predict that 39 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 80,000 ft2 of floor area, the equivalent of about two floors. NIST will say that the loss of fireproofing is a major cause of the collapse (see April 5, 2005), but only performs 15 tests on fireproofing samples (see October 26, 2005). [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 41 ] According to NIST, less fireproofing is stripped from the North Tower (see 8:46 a.m. September 11, 2001).

[CAPE COD TIMES, 8/21/2002] The other Otis pilot, Lieutenant Colonel Timothy Duffy, recalls, “We’re 60 miles out, and I could see the smoke from the towers.” They call NORAD’s Northeast Air Defense Sector (NEADS) for an update, and, as Duffy will recall: “At that point, they said the second aircraft just hit the World Trade Center. That was news to me. I thought we were still chasing American [Airlines Flight] 11.” [ABC NEWS, 9/14/2002] In another account Duffy will relate: “It was right about then when they said the second aircraft had just hit the World Trade Center, which was quite a shock to both [Nash] and I, because we both thought there was only one aircraft out there. We were probably 70 miles or so out when the second one hit. So, we were just a matter of minutes away.” [BBC, 9/1/2002] He asks NEADS for clarification of their mission, but the request is met with “considerable confusion.” [AVIATION WEEK AND SPACE TECHNOLOGY, 6/3/2002] Bob Varcadipane, a Newark, New Jersey, air traffic controller who sees the Flight 175 crash, will claim: “I remember the two F-15s. They were there moments after the impact. And I was just—said to myself, ‘If only they could have gotten there a couple minutes earlier.’ They just missed it.” [MSNBC, 9/11/2002] However, the 9/11 Commission appears to believe that the pilots never get near New York City at this time. According to the Commission’s account, lacking a clear target, the Otis fighters took off toward military controlled airspace over the ocean, off the coast of Long Island. A map released by the Commission indicates that at 9:03 they are about 100 miles away and heading southwest instead of west to New York City. [9/11 COMMISSION, 6/17/2004] Tape recordings of the NEADS operations floor reveal Major Kevin Nasypany telling Colonel Robert Marr, “Fighters are south of—just south of Long Island.” [VANITY FAIR, 8/1/2006] The 9/11 Commission says that, at 9:10 a.m., the FAA’s Boston Center tells the Otis fighters about the second WTC tower being struck.

The alarms warn there is no water pressure and that the building’s emergency power generator has been activated. Office of Emergency Management (OEM) staff, based in Building 7, immediately request air security over New York. They are told that federal support is on its way, but the Federal Aviation Administration instructs them to use NYPD and Port Authority Police Department air assets to clear the airspace around the WTC. They are also warned that the Kennedy Airport control tower is reporting an unaccounted for plane heading towards New York. A report by the Mineta Transportation Institute will claim that this plane is Flight 93, which later crashes in Pennsylvania. [JENKINS AND EDWARDS-WINSLOW, 9/2003, PP. 16] However, Flight 93 is still flying west at this time, and only reverses course and heads towards Washington at around 9:36 a.m. (see (9:36 a.m.) September 11, 2001).

Brian Clark. [Source: CTV] Brian Clark, the executive vice president of brokerage firm Euro Brokers, was on the 84th floor of the South Tower, where his firm’s offices are, when Flight 175 crashed into it. He had headed out, going down Stairway A, which is the only staircase in the tower that remains intact from top to bottom, and was soon joined by Stanley Praimnath, who also works in the South Tower. They reach a point that Clark later guesses to have been around the 77th or 78th floor, where the stairway walls are cracked, allowing them to look through. This would be around the lower end of the floors where the plane impacted. However, Clark sees no large fire. He later says, “[Y]ou could look through the cracks and see flames. They were just quietly licking up, not a roaring inferno. And there was some smoke there, but again I think the stairs were pressurized, pushing the air out so we had less smoke in the stairway than you might imagine.” [BBC, 3/7/2002; NEW YORK TIMES, 5/26/2002; SUN, 9/6/2002; 9/11 COMMISSION, 5/18/2004] This apparently contradicts later claims that the tower was subjected to “extreme fires” prior to its collapse. [NEW YORK TIMES, 10/20/2004] Firefighter Orio Palmer will make it up to this level of the tower later on, and also report only finding small fires there (see 9:52 a.m. September 11, 2001). Clark and Praimnath continue down the stairs and make it out just minutes before the collapse. They are two of only four people who were at or above the impact zone after Flight 175 hit, who are able to escape from the South Tower.

9:13 a.m. September 11, 2001: Jet Fuel in South Tower Burns Up The jet fuel that spilled from Flight 175 when it hit the South Tower (see 9:03 a.m. September 11, 2001) has mostly burned up by this time. The National Institute of Standards and Technology (NIST), which later investigates the collapses, will say the “initial jet fuel fires themselves lasted at most a few minutes.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 183 ] Engineering professor Forman Williams will say the jet fuel “burned for maybe 10 minutes.” [POPULAR MECHANICS, 3/2005] Flight 175, a Boeing 767, had a capacity of 23,980 gallons, but was only carrying about 9,100 gallons of fuel when it hit the WTC. NIST will estimate that less than 1,500 gallons were consumed in a fireball inside the tower and 910 to 2,275 gallons were consumed in the fireballs outside the building. Approximately 6,100 gallons therefore splashed onto the office furnishings and started fires on various floors. However, after the jet fuel is used up, office fires burn until the building collapses. NIST will calculate that there were about four pounds per square foot of combustibles in the office space, or about 60 tons per floor. Offices in the WTC actually had fewer combustibles than other similar spaces due to the small number of interior walls and limited bookshelf space. NIST will later find that only three of sixteen perimeter columns it recovers reached a temperature of 250°C and neither of the two core columns it retrieves reached this temperature. NIST will also find that none of the samples it acquires reached a temperature above 600°C (see August 27, 2003). While steel does not melt until its temperature is about 1,600°C, it may begin to lose significant strength at over 500°C. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 29, 38, 42, 77 ] The jet fuel also burned up in the North Tower about 10 minutes after it was hit (see 8:57 a.m. September 11, 2001). When a group of firefighters reach the bottom impact floor in the South Tower just before collapse, they only find two isolated fires (see 9:52 a.m. September 11, 2001).

(9:21 a.m.-9:59 a.m. September 11, 2001): Exterior Wall of South Tower May Bow Outwards or Inwards before Collapse The exterior wall on the east side of the World Trade Center’s South Tower apparently bows before the building collapses. The first inquiry into the collapse, by the Federal Emergency Management Agency and the American Society of Civil Engineers, states that the perimeter walls bow outward. “Expansion of floor slabs and framing results in outward deflection of columns and potential overload,” the investigation concludes. [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 2-25] However, a subsequent report by the National Institute of Standards and Technology states that the east wall of the South Tower bows inward. In places the wall is said to bow inward by between seven and nine inches at floor 80, and NIST interprets this bowing to mean that the floors must be sagging. NIST will find that the sagging and bowing are two of the seven major factors that led to the collapse of each tower, as the bowing walls are no longer able to support their share of the buildings’ weight, causing the buildings to tilt and the upper sections to fall. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 43-46, 87 ] A wall in the North Tower also apparently bows before the building collapses (see 10:23 a.m. September 11, 2001).

9:47 a.m. September 11, 2001: Internal Collapse at WTC South Tower Reported A man who is on the 105th floor of the South Tower calls emergency 9-1-1 to report that floors below his location, “in the 90-something floor,” have collapsed. The 9-1-1 operator types a record of this call into the Special Police Radio Inquiry Network (SPRINT) data link, which will be passed on to the New York fire department’s Emergency Medical Service (EMS). It isn’t known when the call is made exactly, but the EMS Dispatch computer apparently receives the call record at this time. However, because it is classified as a “supplement message,” it is not yet read by anyone. The police dispatcher dealing with the area around the WTC also receives the call record, but misinterprets it as meaning that the floor the person is on has collapsed. EMS dispatchers are dealing with an enormous volume of calls as well as performing many other tasks under extreme pressure during the crisis, so a report later concludes that the EMS operators didn’t have the time to review the information before the collapse of the South Tower at 9:59 (see 9:59 a.m. September 11, 2001), and the fire chiefs never received the information.

(9:50 a.m.) September 11, 2001: Molten Metal Pours from South Tower

Molten metal pouring out of the side of the World Trade Center. [Source: Cameraplanet] Video footage later reveals that in the minutes immediately before the collapse of the WTC’s South Tower, a stream of molten metal starts pouring out of a window opening around the northeast corner of its 80th floor. FEMA later suggests that this is “possibly aluminum from the airliner,” and comments, “This is of particular interest because, although the building collapse appears to have initiated at this floor level, the initiation seems to have occurred at the southeast rather than the northeast corner.” [CIVIL ENGINEERING, 5/2002; FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 2-34; DWYER AND FLYNN, 2005, PP. 207] According to the National Institute of Standards and Technology, “The composition of the flowing material can only be the subject of speculation, but its behavior suggests it could have been molten aluminum.” [PITTS, BUTLER, AND JUNKER, 9/2005, PP. 375] However physics professor Steven E. Jones will in 2006 dispute this, saying that molten aluminum is silvery and never turns yellow, like what is in the video footage. He will instead claim the presence of this molten metal supports the theory that explosives, specifically thermite, are what caused the Twin Towers to collapse. He says thermite can cause steel to melt and become yellowish. [DESERET MORNING NEWS, 4/10/2006] Entity Tags: World Trade Center Timeline Tags: Complete 911 Timeline, 9/11 Timeline

[NEW YORK TIMES, 8/4/2002] They are just two floors below the level where, minutes later, its collapse initiates. [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 2-34] Over radio, Palmer tells firefighter Joseph Leavey, “We’ve got two isolated pockets of fire. We should be able to knock it down with two lines.” [DWYER AND FLYNN, 2005, PP. 206] The fact that they reached so high up the tower only comes to light almost a year later, when a tape of radio communications from 9/11 is made public (see August 4, 2002). The New York Times will report “[N]owhere on the tape is there any indication that firefighters had the slightest indication that the tower had become unstable or that it could fall.” [NEW YORK TIMES, 11/9/2002] Palmer’s communication appears to contradict claims that “extreme fires” contributed to the tower’s collapse.

Will Jimeno. [Source: Todd Plitt / USA Today] Some witnesses reportedly see a massive fireball at ground level, coming from the South Tower just before it starts to collapse. According to a report by the Mineta Transportation Institute (a research institute founded by Transportation Secretary Norman Mineta), “People inside the South Tower felt the floor vibrate as if a small earthquake were occurring.… The vibration lasted for about 30 seconds. The doors were knocked out, and a huge ball of flame created by the exploding diesel fuel from the building’s own supply tank shot from the elevator shaft and out the doors of the South Tower, consuming everything in its path. Minutes later, at 9:59 a.m., the tower collapsed.” [JENKINS AND EDWARDS-WINSLOW, 9/2003, PP. 16] Around the same time, Port Authority Police Officer Will Jimeno is in a corridor leading toward the North Tower. “Suddenly the hallway began to shudder,” and he sees “the giant fireball explode in the street,” when the South Tower begins to collapse.

(Before 9:59 a.m.) September 11, 2001: EMT Worker Given Message That WTC Towers Are Going to Collapse; High-Level Officials Evacuate Lobby of North Tower

Fireman Mike Kehoe heads upstairs while others flee downstairs. Kehoe luckily survived the building collapses. [Source: John Labriola] In the lobby of Building 7 of the WTC, EMS Division Chief John Peruggia is in discussion with Fire Department Captain Richard Rotanz and a representative from the Department of Buildings. As Peruggia later describes, “It was brought to my attention, it was believed that the structural damage that was suffered to the [Twin] Towers was quite significant and they were very confident that the building’s stability was compromised and they felt that the North Tower was in danger of a near imminent collapse.” Peruggia grabs EMT Richard Zarrillo and tells him to pass on the message “that the buildings have been compromised, we need to evacuate, they’re going to collapse.” Zarrillo heads out to the fire command post, situated in front of 3 World Financial, the American Express Building, where he relays this message to several senior firefighters. He says, “OEM says the buildings are going to collapse; we need to get out.” (OEM is the Mayor’s Office of Emergency Management, which has its headquarters in WTC 7.) Fire Chief Pete Ganci’s response is, “who the f___ told you that?” Seconds later, they hear the noise of the South Tower as it collapses.

(Before 9:59 a.m.) September 11, 2001: Giuliani Apparently Told WTC Towers Will Collapse When Fire Chiefs Think Otherwise

Mayor Rudolph Giuliani will become well known for his walking press conferences in the middle of the 9/11 crisis. [Source: Time Magazine/ Salient Stills] Between 9:25 a.m. and 9:45 a.m., one senior New York fire chief recommends to the Fire Department Chief of Department that there might be a WTC collapse in a few hours, and, therefore, fire units probably shouldn’t ascend much above the sixtieth floor (presumably this assumes the collapse would be gradual so those on lower floors would still have time to evacuate). This advice is not followed or not passed on. Apparently, no other senior fire chiefs mention or foresee the possibility of the WTC towers falling. [9/11 COMMISSION, 5/19/2004] However, New York City Mayor Rudolph Giuliani recounts, “I went down to the scene and we set up headquarters at 75 Barclay Street, which was right there, with the police commissioner, the fire commissioner, the head of emergency management, and we were operating out of there when we were told that the World Trade Center was going to collapse. And it did collapse before we could actually get out of the building, so we were trapped in the building for ten, 15 minutes, and finally found an exit and got out, walked north, and took a lot of people with us.” [ABC NEWS, 9/11/2001] As can be seen by another account of similar events, this happens before the first WTC tower falls, not the second. [9/11 COMMISSION, 5/19/2004] It is not clear who tells Giuliani to evacuate when no fire chiefs were considering the possibility of an imminent collapse. However, an EMT is also given a message around this time, warning that the towers are going to collapse. The origin of this information is apparently the Mayor’s Office of Emergency Management, so this may also have been from where Giuliani heard of the imminent collapse (see (Before 9:59 a.m.) September 11, 2001).

He asks her, “Are [the hijackers] going to blow this plane up?” Lyz replies that she doesn’t know, but tells him that it is true two planes have crashed into the World Trade Center. He asks her if they’re going to crash the plane into the World Trade Center. She replies, “No. They’re not going there.” He asks why, and she replies that one of the towers has just fallen. “They knocked it down.” The first World Trade Center tower collapses at 9:59 and is seen by millions on television. The book makes clear that this exchange takes place at “almost ten o’clock” —within a minute of the tower collapse. [LONGMAN, 2002, PP. 147] This account contradicts the 9/11 Commission’s conclusion that the passenger assault on the cockpit begins at 9:58, because the tower collapse was definitely at 9:59. Only later in the same phone call does Jeremy Glick mention that passengers are still taking a vote on whether or not to attack the hijackers. He confers with others and tells Lyz that they’ve decided to do so, and then gets off the phone line.

9:59 a.m. September 11, 2001: Some Witnesses Think South Tower Collapse Resembles a Controlled Demolition

Deputy Fire Commissioner Thomas Fitzpatrick. [Source: City of New York] Numerous witnesses to the collapse of the south WTC tower think it resembles a demolition using explosives. Some initially believe this is what is occurring: Reporter John Bussey watches the collapse from the Wall Street Journal’s offices across the street from the WTC. He says, “I… looked up out of the office window to see what seemed like perfectly synchronized explosions coming from each floor, spewing glass and metal outward. One after the other, from top to bottom, with a fraction of a second between, the floors blew to pieces.” [WALL STREET JOURNAL, 9/12/2001] Deputy Fire Commissioner Thomas Fitzpatrick: “I remember seeing, it looked like sparkling around one specific layer of the building.… Then the building started to come down. My initial reaction was that this was exactly the way it looks when they show you those implosions on TV.” [CITY OF NEW YORK, 10/1/2001] Assistant Fire Commissioner Stephen Gregory: “I saw low-level flashes. In my conversation with Lieutenant Evangelista… he questioned me and asked me if I saw low-level flashes in front of the building, and I agreed with him… I saw a flash flash flash and then it looked like the building came down.… You know like when they demolish a building, how when they blow up a building, when it falls down? That’s what I thought I saw.” [CITY OF NEW YORK, 10/3/2001] Firefighter Richard Banaciski: “It seemed like on television they blow up these buildings. It seemed like it was going all the way around like a belt, all these explosions.” [CITY OF NEW YORK, 12/6/2001] Firefighter Joseph Meola: “As we are looking up at the building, what I saw was, it looked like the building was blowing out on all four sides. We actually heard the pops.… You thought it was just blowing out.” [CITY OF NEW YORK, 12/11/2001] Fire Chief Frank Cruthers: “[T]here was what appeared to be at first an explosion. It appeared at the very top, simultaneously from all four sides, materials shot out horizontally. And then there seemed to be a momentary delay before you could see the beginning of the collapse.” [CITY OF NEW YORK, 10/31/2001] Battalion Chief Brian Dixon: “I was watching the fire… the lowest floor of fire in the South Tower actually looked like someone had planted explosives around it because the whole bottom I could see—I could see two sides of it and the other side—it just looked like that floor blew out.… I thought, geez, this looks like an explosion up there, it blew out.” [CITY OF NEW YORK, 10/25/2001] Firefighter Timothy Burke: “Then the building popped, lower than the fire… I was going oh, my god, there is secondary device because the way the building popped I thought it was an explosion.” [CITY OF NEW YORK, 1/22/2002] Firefighter Edward Cachia: “It actually gave at a lower floor, not the floor where the plane hit, because we originally had thought there was like an internal detonation explosives because it went in succession, boom, boom, boom, boom, and then the tower came down.” [CITY OF NEW YORK, 12/6/2001] Firefighter Kenneth Rogers: “[T]here was an explosion in the South Tower… I kept watching. Floor after floor after floor. One floor under another after another and when it hit about the fifth floor, I figured it was a bomb, because it looked like a synchronized deliberate kind of thing.” [CITY OF NEW YORK, 12/10/2001] Reporter Beth Fertig: “The tower went down perfectly straight, as if a demolition crew had imploded it. I wondered if it was being brought down deliberately.” [GILBERT ET AL., 2002, PP. 78] Paramedic Daniel Rivera: “[D]o you ever see professional demolition where they set the charges on certain floors and then you hear ‘Pop, pop, pop, pop, pop’?

[NEWSWEEK, 12/31/2001] According to the Washington Post, three people who are present say they see no sign now or later “of the profound psychological transformation that has often been imputed to Cheney.” What they see is “extraordinary self-containment and a rapid shift of focus to the machinery of power. While others assessed casualties and the work of ‘first responders,’ Cheney began planning for a conflict that would call upon lawyers as often as soldiers and spies.” He will promptly begin assembling the legal team that subsequently assists him in expanding presidential power (see (After 10:00 a.m.) September 11, 2001).

10:23 a.m. September 11, 2001: Exterior Wall of North Tower May Bow Outwards or Inwards before Collapse The exterior wall on the south side of the World Trade Center’s North Tower apparently bows before the building collapses. The first inquiry into the collapse, by the Federal Emergency Management Agency and the American Society of Civil Engineers, states that the perimeter walls bow outward (see (9:21 a.m.-9:59 a.m. September 11, 2001)). However, a subsequent report by the National Institute of Standards and Technology states that the south wall of the North Tower bows inward. In places the wall is said to bow inward by approximately 55 inches at floor 97, and NIST interprets this bowing to mean that the floors must be sagging. NIST will find that the sagging and bowing are two of the seven major factors that led to the collapse of each tower, as the bowing walls are no longer able to support their share of the buildings’ weight, causing the buildings to tilt and the upper sections to fall.

10:28 a.m. September 11, 2001: Some Witnesses Hear Explosions as North Tower Collapses

Fire Lieutenant Gregg Hansson [Source: BBC] Many witnesses hear explosions during the collapse of the north WTC tower. Some report hearing a single explosion: Reporter Mike Sheehan hears “another deafening explosion. I looked up and saw the top of the North Tower, the mast, begin to fall.” [GILBERT ET AL., 2002, PP. 126] Fire Lieutenant William Wall: “[W]e heard an explosion. We looked up and the building was coming down right on top of us.” [CITY OF NEW YORK, 12/10/2001] Firefighter Roy Chelsen: “All of a sudden we heard this huge explosion, and that’s when the tower started coming down.” [CITY OF NEW YORK, 1/18/2002] EMT Jason Charles: “I heard a ground level explosion and I’m like holy shit, and then you heard that twisting metal wreckage again.” [CITY OF NEW YORK, 1/23/2002] Firefighter Kevin Murray: “When the tower started—there was a big explosion that I heard and someone screamed that it was coming down.” [CITY OF NEW YORK, 10/9/2001] Firefighter James Ippolito: “I heard an explosion and turned around and the building was coming down.” [CITY OF NEW YORK, 12/13/2001] Fire Lieutenant Gregg Hansson: “[A] large explosion took place. In my estimation that was the tower coming down, but at that time I did not know what that was. I thought some type of bomb had gone off.” [CITY OF NEW YORK, 10/9/2001] Firefighter Kevin Gorman: “I heard the explosion, looked up, and saw like three floors explode, saw the antenna coming down.” [CITY OF NEW YORK, 1/9/2002] Others report hearing multiple explosions: EMT Gregg Brady: “I heard 3 loud explosions. I look up and the North Tower is coming down now.” [CITY OF NEW YORK, 11/1/2001] Firefighter Richard Carletti: “I remember seeing the antenna do a little rock back and forth and I could just hear the floors pancaking. I heard it for about 30 pancakes, just boom, boom, boom, boom.” [CITY OF NEW YORK, 1/2/2002] Fire Lieutenant Michael Cahill: “That’s when the second collapse started to come down. All kinds of noise. Boom, boom, boom, boom, boom, very loud.” [CITY OF NEW YORK, 10/17/2001] Firefighter Sal D’Agostino is actually inside the North Tower, around its fourth floor, when the collapse occurs. He says, “It’s pancaking from the top down, and there were these huge explosions—I mean huge, gigantic explosions.” [PROVIDENCE JOURNAL, 9/11/2002; DWYER AND FLYNN, 2005, PP. 241-242] Firefighter Bill Butler, who is with D’Agostino inside the tower, says, “It was like a train going two inches away from your head: bang-bang, bang-bang, bang-bang.” [PROVIDENCE JOURNAL, 9/11/2002] EMT David Timothy: “[Y]ou started hearing more explosions. I guess this is when the second tower started coming down.” [CITY OF NEW YORK, 10/25/2001] CTV will later assert, “When eyewitnesses claim to have heard explosions prior to the collapse, those were just the sounds of a massive building contorting and crushing anything inside.” [CTV, 9/12/2006] Entity Tags: Jason Charles, Roy Chelsen, James Ippolito, Bill Butler, David Timothy, Kevin Gorman, Kevin Murray, Mike Sheehan, Gregg Brady, World Trade Center, Michael Cahill, William Wall, Richard Carletti, Gregg Hansson, Sal D’Agostino Timeline Tags: Complete 911 Timeline, 9/11 Timeline

10:28 a.m. September 11, 2001: Some Witnesses Think North Tower Collapses Like a Controlled Demolition Some witnesses to the collapse of the North Tower think it resembles a demolition using explosives: Fire Captain Dennis Tardio: “I hear an explosion and I look up. It is as if the building is being imploded, from the top floor down, one after another, boom, boom, boom.” [SMITH, 2002, PP. 18] Assistant Fire Commissioner James Drury: “[P]eople in the street and myself included thought that the roar was so loud that the explosive—bombs were going off inside the building.” [CITY OF NEW YORK, 10/16/2001] Firefighter James Curran: “I heard like every floor went chu-chu-chu. Looked back and from the pressure everything was getting blown out of the floors before it actually collapsed.” [CITY OF NEW YORK, 12/30/2001] EMS Captain Karin Deshore: “Somewhere around the middle of the World Trade Center, there was this orange and red flash coming out. Initially it was just one flash. Then this flash just kept popping all the way around the building and that building had started to explode. The popping sound, and with each popping sound it was initially an orange and then a red flash came out of the building and then it would just go all around the building on both sides as far as I could see. These popping sounds and the explosions were getting bigger, going both up and down and then all around the building. I went inside… and I said I think we have another major explosion.” [CITY OF NEW YORK, 11/7/2001] The National Institute of Standards and Technology, in its report on the towers’ collapse, will reject suggestions that the Twin Towers were brought down with explosives (see August 30, 2006).

10:28 a.m. September 11, 2001: WTC 7 Damaged When North Tower Collapses

Damage to the southwest corner of WTC 7. [Source: Arquelio Galarza] World Trade Center Building 7 (WTC 7) suffers some damage, caused by debris from the collapse of the north WTC tower, according to later official reports. [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 5-16; NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. 16 ] WTC 7 Undamaged by South Tower Collapse - WTC 7 is a 47-story office building located 370 feet north of the North Tower (WTC 1). In the final report of its investigation into WTC 7’s collapse, published in November 2008 (see November 20, 2008), the National Institute of Standards and Technology (NIST) will state that although a few windows on the lower floors of WTC 7’s south face were broken when the South Tower (WTC 2) collapsed at 9:59 a.m. (see 9:59 a.m. September 11, 2001), “None of the large pieces of debris from WTC 2 hit WTC 7, because of the large distance between the two buildings,” and there is “no evidence of structural damage to WTC 7” as a result of the South Tower’s collapse. Debris Reportedly Damages Exterior Columns - However, when the North Tower collapses (see 10:28 a.m. September 11, 2001), some fragments of debris are “forcibly ejected” from it, and travel “distances up to hundreds of meters.” According to NIST, pieces of this debris “hit WTC 7, severing six columns on floors 7 through 17 on the south face and one column on the west face near the southwest corner.” NIST will add that the debris also causes “structural damage between floor 44 and the roof,” and breaks a large number of windows on WTC 7’s south face. Building Core Undamaged - However, NIST will state, based on “photographic evidence, witness accounts, and engineering judgment, it is likely that the structural damage (steel and floor slabs) did not penetrate beyond the perimeter of the building core. At the southwest corner, the structural damage extended only about one-third of the distance from the exterior wall to the building core.” NIST will comment, “Compared to the airplane impact damage to the WTC towers, there was relatively little damage to the interior of WTC 7.” There is also “no superficial or structural damage” to WTC 7’s north and east faces. And the sprayed fire resistive material that has been applied to the building’s steel columns, girders, and beams is only damaged in the “immediate vicinity of the WTC 1 debris impact.” NIST will admit, however, that there are “uncertainties” in its accounting of the events leading up to the collapse of WTC 7, because “the remains of all the WTC buildings were disposed of before Congressional action and funding was available for [its] investigation [of the WTC collapses] to begin” (see Shortly After September 11, 2001 and September 12-October 2001). [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 8/21/2008; NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. 15-16 ] FEMA Describes WTC 7 Damage - According to an earlier report on the collapse of WTC 7, published by the Federal Emergency Management Agency (FEMA) in May 2002 (see May 1, 2002), at that time, the “extent and severity of the resulting damage to WTC 7” when the North Tower collapses “are currently unknown.” But based on “photographic evidence and eyewitness accounts,” it is “assumed that the south side of the building was damaged to some degree.” FEMA’s report will state: “It does not appear that the collapse of WTC 1 affected the roof, or the east, west, and north elevations of WTC 7 in any significant way. However, there was damage to the southwest corner of WTC 7 at approximately floors 8 to 20, 24, 25, and 39 to 46.” The report will add: “According to firefighters’ eyewitness accounts from outside of the building, approximately floors 8-18 were damaged to some degree. Other eyewitness accounts relate that there was additional damage to the south elevation.” [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 5-16, 5-20] Structural Damage Not Responsible for Collapse - WTC 7 will collapse at 5:20 p.m. this afternoon (see (5:20 p.m.) September 11, 2001). [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 8/21/2008] However, NIST will conclude that the structural damage the building suffers plays no role in causing it to come down. NIST will state, “Other than initiating the fires in WTC 7, the damage from the debris from WTC 1 had little effect on initiating the collapse of WTC 7.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. XXXVII ] WTC 7 suffers fires on some floors, which are reportedly initiated by debris from the collapse of the North Tower (see (10:28 a.m.-5:20 p.m.) September 11, 2001). According to NIST, it is these fires, “rather than the structural damage that resulted from the impacts” of debris, which “initiated the building’s collapse.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 8/21/2008] Entity Tags: National Institute of Standards and Technology, World Trade Center, Federal Emergency Management Agency

(10:28 a.m.-5:20 p.m.) September 11, 2001: WTC 7 Suffers Fires ‘on at Least 10 Floors’ World Trade Center Building 7 (WTC 7) suffers fires on several floors, some of which last until 5:20 p.m., when the building collapses. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 8/21/2008] WTC 7 is a 47-story office building located just north of the Twin Towers. It is damaged when the north WTC tower (WTC 1) collapses at 10:28 a.m. (see 10:28 a.m. September 11, 2001). [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. 2, 16 ] Fires Started by Collapse Debris - Two official reports on the collapse of WTC 7 will tentatively conclude that fires in this building are initiated by debris that is ejected when the North Tower collapses (see 10:28 a.m. September 11, 2001). In a 2002 report (see May 1, 2002), the Federal Emergency Management Agency (FEMA) will state, “It is likely that fires” in WTC 7 “started as a result of debris from the collapse of WTC 1.” [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 5-20] In a 2008 report (see November 20, 2008), the National Institute of Standards and Technology (NIST) will state, “Most likely, the WTC 7 fires began as a result of burning debris from the collapse of WTC 1.” However, NIST will add, “visual evidence of fires in the building was not available until around noon.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. 18 ] Fires Spread in WTC 7 - According to NIST, fires are ignited “on at least 10 floors” of WTC 7, but “only the fires on floors 7 through 9 and 11 through 13 grew and lasted until the time of the building collapse.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. XXXVI ] NIST will state, “Early fires were seen on the southwest corner of floors 19, 22, 29, and 30 shortly after noon,” but “These were short-lived.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. 51 ] The fires on floors 7 to 9 and 11 to 13, however, “grew and spread, since they were not extinguished either by the automatic sprinkler system or by [the New York City Fire Department], because water was not available in WTC 7.” Fires are “generally concentrated on the east and north sides of the northeast region beginning at about 3 p.m. to 4 p.m.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. 21 ] The fires on floors 7 to 9 and 11 to 13 have “characteristics similar to those that have occurred previously in tall buildings,” according to NIST, and “Their growth and spread [are] consistent with ordinary building contents fires.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. XXXVI ] These fires are “fed by combustibles (e.g., desks, chairs, papers, carpet) that were ordinary for commercial occupancies.” However, NIST will point out, there is “no evidence that the fires spread from floor to floor, except, perhaps, just prior to the collapse of the building.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. 51-52 ] Limited Evidence Available - Both FEMA and NIST will admit that their accounts of the fires in WTC 7 are based upon imperfect evidence. In its report on the WTC collapses, published in May 2002, FEMA will note, “Currently, there is limited information about the ignition and development of fires at WTC 7.” [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 5-20] In the final report of its investigation of the collapse of WTC 7, NIST will point out that “available images showing fires in WTC 7 did not allow the detailed description of fire spread that was possible for the WTC towers.” The report will add: “It must be kept in mind that [NIST’s] fire observations were based on images of the exterior faces, which provided little indication about the behavior of fires well removed from the exterior walls. It is likely that much of the burning took place beyond the views of the windows.” But, the report will state, “[T]here was sufficient information to derive general descriptions of fire ignition and spread on various floors of the building.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. 18 ] NIST Blames Fires for Collapse - WTC 7 collapses at 5:20 p.m. this afternoon (see (5:20 p.m.) September 11, 2001). In late 2008, at the end of its investigation into WTC 7’s collapse, NIST will blame the fires WTC 7 suffers for causing its collapse (see August 21, 2008 and August 21, 2008). NIST will state: “The heat from the uncontrolled fires caused steel floor beams and girders to thermally expand, leading to a chain of events that caused a key structural column to fail. The failure of this structural column then initiated a fire-induced progressive collapse of the entire building.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 8/21/2008; NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. XXXVI-XXXVII ] However, critics will dispute this conclusion, instead blaming explosives for the collapse (see August 21, 2008). [NEW YORK TIMES, 8/21/2008] FEMA will offer no firm conclusions about the possible role fires play in causing WTC 7 to collapse. In its 2002 report it will state, “The specifics of the fires in WTC 7 and how they caused the building to collapse remain unknown at this time.” [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 5-31] Entity Tags: Federal Emergency Management Agency, World Trade Center, National Institute of Standards and Technology

(10:28 a.m. September 11, 2001): Falling Antenna Suggests North Tower’s Collapse Begins in Its Core Area The team studying the WTC collapses for the American Society of Civil Engineers (ASCE) and the Federal Emergency Management Agency (FEMA) will later observe that the antenna on WTC 1 began to fall before the exterior of the building: “Review of videotape recordings of the collapse taken from various angles indicates that the transmission tower on top of the structure began to move downward and laterally slightly before movement was evident at the exterior wall. This suggests that collapse began with one or more failures in the central core area of the building.” [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 2-27] In a program featuring some members of the FEMA/ASCE team, the BBC will comment: “The mast was directly supported by the tower’s inner core. The way it fell suggests it was failure of the inner core that began the collapse, whereas in the South Tower it had been the outer walls.” [BBC, 3/7/2002] Entity Tags: American Society of Civil Engineers, World Trade Center, Federal Emergency Management Agency Timeline Tags: Complete 911 Timeline, 9/11 Timeline

After 10:28 a.m. September 11, 2001: Fire Fighters Trying to Extinguish Fires in WTC 7 According to Captain Michael Currid, the sergeant at arms for the Uniformed Fire Officers Association, some time after the collapse of the North Tower, he sees four or five fire companies trying to extinguish fires in Building 7 of the WTC. Someone from the city’s Office of Emergency Management tells him that WTC 7 is in serious danger of collapse. Currid says, “The consensus was that it was basically a lost cause and we should not lose anyone else trying to save it.” Along with some others, he goes inside WTC 7 and yells up the stairwells to the fire fighters, “Drop everything and get out!” [MURPHY, 2002, PP. 175-176] However, other accounts contradict this, claiming that no attempt is made to fight the fires in WTC 7 (see (11:30 a.m.) September 11, 2001). One report later claims, “Given the limited water supply and the first strategic priority, which was to search for survivors in the rubble, FDNY did not fight the fires [in WTC 7].” [FIRE ENGINEERING, 9/2002] And a 2002 government report says, “the firefighters made the decision fairly early on not to attempt to fight the fires, due in part to the damage to WTC 7 from the collapsing towers.” [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 5-21] Building 7 eventually collapses late in the afternoon of 9/11 (see (5:20 p.m.) September 11, 2001).

(Between 12:00 p.m. and 5:00 p.m.) September 11, 2001: World Trade Center Leaseholder Discusses Possible Controlled Demolition of WTC 7 with Insurer, Reporter Will Later Claim

Jeffrey Scott Shapiro. [Source: University of Florida] Larry Silverstein, who recently took over the lease of the World Trade Center complex (see July 24, 2001), discusses possibly bringing down WTC Building 7 in a controlled demolition in a telephone conversation with his insurance carrier, according to a reporter who is at the WTC site this afternoon. [FOX NEWS, 4/22/2010] WTC 7 is a 47-story office building located just north of the Twin Towers. The National Institute of Standards and Technology (NIST) will say it suffered some structural damage (see 10:28 a.m. September 11, 2001) when the North Tower collapsed (see 10:28 a.m. September 11, 2001) and it has fires on several floors (see (10:28 a.m.-5:20 p.m.) September 11, 2001). It will collapse at 5:20 p.m., apparently becoming the first tall building ever to come down primarily as a result of fire (see (5:20 p.m.) September 11, 2001). [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. XXXV-XXXVI ] Silverstein Allegedly Wants WTC 7 Demolished - Investigative reporter Jeffrey Scott Shapiro, who is at the scene of the attacks in New York, will later recall: “Shortly before [WTC 7] collapsed, several NYPD officers and Con Edison workers told me that Larry Silverstein… was on the phone with his insurance carrier to see if they would authorize the controlled demolition of the building, since its foundation was already unstable and expected to fall. A controlled demolition would have minimized the damage caused by the building’s imminent collapse and potentially save lives.” Shapiro will add: “Many law enforcement personnel, firefighters, and other journalists were aware of this possible option. There was no secret.” [FOX NEWS, 4/22/2010] Preparing a large building for demolition usually takes weeks, or even months. This time is spent on operations such as wrapping concrete columns to ensure pieces do not fly off. [BALTIMORE SUN, 2/26/1995; PBS NOVA, 12/1996; CONSTRUCTION EQUIPMENT GUIDE, 2/24/2005] Discussion of Demolition Later Denied - Silverstein will later recall discussing WTC 7 over the phone with the commander of the New York Fire Department, and telling him, “We’ve had such terrible loss of life, maybe the smartest thing to do is pull it” (see After 12:00 Noon September 11, 2001), but a spokesman will subsequently claim that Silverstein was referring to withdrawing firefighters from the building, not bringing WTC 7 down with explosives. [US DEPARTMENT OF STATE, 9/16/2005; BBC, 7/4/2008] At the end of a three-year investigation into the building’s collapse, NIST will say WTC 7 “did not collapse from explosives,” but critics will dispute this conclusion (see August 21, 2008).

(2:00 p.m.-2:30 p.m.) September 11, 2001: Decision Made to Abandon WTC 7 The chief fire officer who has been assigned to take charge of operations at WTC Building 7 meets with his command officer, to discuss the condition of this building and the fire department’s capabilities for controlling the fires in it. A deputy fire chief who has just been in WTC 7, inspecting up to its 7th or 8th floor, reports that there was a lot of fire inside and the stairway was filling with smoke. The fire chiefs discuss the situation and identify the following conditions: WTC 7 has suffered damage caused by falling debris from the Twin Towers, and they are uncertain about its structural stability. There are large fires on at least six floors. They do not have enough equipment available for conducting operations in the building, such as hoses, standpipe kits, and handie-talkies. There is no water immediately available for fighting the fires. (However, this concern is apparently contradicted by reports that two or three fireboats are moored nearby, specifically to provide water-pumping capacity for the WTC site.) Therefore, at around 2:30 p.m., fire officers decide to completely abandon WTC 7 and a final order is given to evacuate the site. Firefighters and other emergency workers will be withdrawn from the surrounding area (see (4:30 p.m.) September 11, 2001), and Building 7 collapses later in the afternoon (see (5:20 p.m.) September 11, 2001).

3:56 p.m. September 11, 2001: Five Apparent Israeli Spies Arrested for Puzzling Behavior at Time of First WTC Attack

The white van used by five Israeli agents as they were leaving New York on 9/11. Five Israelis are arrested for “puzzling behavior” related to the WTC attacks. Shortly after an FBI lookout bulletin was issued for a van with the words “Urban Moving Systems” written on the side, officers with the East Rutherford Police Department in New Jersey stop the van after matching the license plate number with the one given in the bulletin. According to the police report, Officer Scott DeCarlo and Sgt. Dennis Rivelli approach the van and demand the driver exit the vehicle. The driver, Sivan Kurzberg, does not obey after being asked several more times, so the police physically remove Kurzberg and four other men from the van and handcuff them. They have not been told the reasons for their arrest, but Kurzberg tells them, “We are Israeli. We are not your problem. Your problems are our problems. The Palestinians are the problem.” Again before the police have made any mention of the 9/11 attacks, another one of the arrested men says, “[W]e were on the West Side Highway in New York City during the incident.” In fact, it will later be determined they were on the roof of a building at Liberty State Park, watching and videotaping the first crash into the WTC (see Shortly After 8:46 a.m. September 11, 2001). [BERGEN RECORD, 9/12/2001; HA'ARETZ, 9/17/2001; COUNTERPUNCH, 2/7/2007] The FBI and additional police quickly arrive. They shut down the section of Route 3 in East Rutherford where the van was stopped and evacuate a nearby hotel as a security precaution. [BERGEN RECORD, 9/12/2001] One man is found with $4,700 in cash hidden in his sock, another has two foreign passports on him, and a box cutter is found in the van. [ABC NEWS, 6/21/2002] Another has pictures of the men standing with the burning wreckage of the WTC in the background. [FORWARD, 3/15/2002] All five identify themselves as Israeli citizens and claim to be working for the New Jersey-based Urban Moving Systems company. In addition to the driver Sivan Kurzberg, the others are identified as Paul Kurzberg (Sivan’s brother), Oded Ellner, Omer Marmari, and Yaron Shmuel. The men are detained but not charged. [FORWARD, 3/15/2002; ABC NEWS, 6/21/2002] The next day it will be reported that “bomb-sniffing dogs reacted as if they had detected explosives.” An investigator high up in the Bergen County law enforcement hierarchy will say in 2006, “There are maps of the city in the car with certain places highlighted…. It looked like they’re hooked in with this [referring to the 9/11 attacks]. It looked like they knew what was going to happen.…It looked like they knew what was going to happen when they were at Liberty State Park.” [BERGEN RECORD, 9/12/2001] The FBI will later conclude at least two of the five are Mossad agents and that all were on a Mossad surveillance mission.

(4:15 p.m.-4:27 p.m.) September 11, 2001: CNN and Others Report WTC 7 May Have Collapsed Building 7 of the World Trade Center, located across the street from the Twin Towers, caught fire after the initial attacks on the WTC. [CNN, 9/12/2001] By 4:10 in the afternoon, CNN had reported it being on fire (see 4:10 p.m. September 11, 2001). Subsequently it is reported that WTC 7 is in danger of collapsing or may have already collapsed. At around 4:15 p.m., CNN reports, “We’re getting information that one of the other buildings… Building 7… is on fire and has either collapsed or is collapsing… now we’re told there is a fire there and that the building may collapse as well.” About 12 minutes later, BBC reporter Greg Barrow, who is in New York, appears on the BBC radio channel Five Live and says, “We are hearing reports from local media that another building may have caught light and is in danger of collapse.” He adds, “I’m not sure if it has yet collapsed but the report we have is talking about Building 7.” Around this time, the area around Building 7 is being evacuated, apparently because senior firefighters have determined it is in danger of collapsing (see (4:30 p.m.) September 11, 2001). At 4:53, based on the earlier reports, the Radio Five Live show’s presenter will incorrectly claim that Building 7 has already collapsed, saying, “Twenty-five minutes ago we had reports from Greg Barrow that another large building has collapsed just over an hour ago.” [BBC, 3/2/2007] Starting at 4:54, BBC television will also begin reporting that Building 7 has already collapsed (see 4:54 p.m.-5:10 p.m. September 11, 2001). In fact, it does not do so until 5:20 (see (5:20 p.m.) September 11, 2001). Entity Tags: World Trade Center, CNN, British Broadcasting Corporation Timeline Tags: Complete 911 Timeline, 9/11 Timeline

[NEW YORK TIMES, 9/11/2002; NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. 5 ] Its representatives who had been in WTC 7 did not think that the building would come down. But, at 4:15 p.m., Con Edison emergency field manager Fred Simms speaks to the New York Fire Department and then tells his company’s headquarters that the fire department thinks WTC 7 will collapse. The fire department then asks Con Edison to shut down the power to WTC 7, which it does. [CITY OF NEW YORK, 6/13/2002; 9/11 COMMISSION, 2/26/2004 ] Electric power to Con Edison’s lower Manhattan substation at WTC 7 is shut off at 4:33 p.m. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 11/2008, PP. 303 ] Also around this time, people are evacuated from the area around WTC 7, due to concerns that the building could collapse (see (4:30 p.m.) September 11, 2001).

(4:30 p.m.) September 11, 2001: WTC Building 7 Area Is Evacuated Due to Anticipated Collapse According to numerous rescue and recovery workers, the area around WTC Building 7 is evacuated at this time. [KANSAS CITY STAR, 3/28/2004] For example: Emergency medical technician Joseph Fortis says, “They pulled us all back at the time, almost about an hour before it, because they were sure—they knew it was going to come down, but they weren’t sure.” [CITY OF NEW YORK, 11/9/2001] Firefighter Edward Kennedy says, ” I remember [Chief Visconti] screaming about 7, No. 7, that they wanted everybody away from 7 because 7 was definitely going to collapse.” [CITY OF NEW YORK, 1/17/2002] Firefighter Vincent Massa: “They were concerned about seven coming down, and they kept changing us, establishing a collapse zone and backing us up.” [CITY OF NEW YORK, 12/4/2001] Firefighter Tiernach Cassidy: “[B]uilding seven was in eminent collapse. They blew the horns. They said everyone clear the area until we got that last civilian out.” [CITY OF NEW YORK, 12/30/2001] Battalion Fire Chief John Norman: “I was detailed to make sure the collapse zone for 7 WTC had been set up and was being maintained.” [FIRE ENGINEERING, 10/2002] Several New York Fire Department chief officers, who have surveyed Building 7, have apparently determined it is in danger of collapsing. [FIRE ENGINEERING, 9/2002] For example, Fire Chief Daniel Nigro explains their decision-making process, saying, “A number of fire officers and companies assessed the damage to the building. The appraisals indicated that the building’s integrity was in serious doubt. I issued the orders to pull back the firefighters and define the collapse zone.” [FIRE ENGINEERING, 9/2002] Fire Chief Frank Fellini says, “We were concerned that the fires on several floors and the missing steel would result in the building collapsing.” [CITY OF NEW YORK, 12/3/2001] And Fire Captain Ray Goldbach says, “[W]e made a decision to take all of our units out of 7 World Trade Center because there was a potential for collapse.” [CITY OF NEW YORK, 10/24/2001] However, some firefighters seem surprised at this decision. When Fire Commissioner Thomas Von Essen is making his way through hundreds of firefighters who are being held away from the WTC site, he hears complaints like, “It could take days for that building to come down,” and, “Why don’t they let us in there?” [ESSEN, 2002, PP. 45] When Deputy Fire Chief Nick Visconti is instructing firefighters to evacuate the area, one comment he receives is, “[O]h, that building is never coming down, that didn’t get hit by a plane, why isn’t somebody in there putting the fire out?” [FIREHOUSE MAGAZINE, 8/2002] Entity Tags: Nick Visconti, Daniel Nigro, Joseph Fortis, John Norman, World Trade Center, Ray Goldbach, Thomas Von Essen, Edward Kennedy, Vincent Massa, Tiernach Cassidy, Frank Fellini Timeline Tags: Complete 911 Timeline, 9/11 Timeline

4:54 p.m.-5:10 p.m. September 11, 2001: BBC Reports WTC 7 Collapse Before It Happens

The BBC’s Jane Standley, reporting the collapse of WTC 7 while it is visible still standing behind her. [Source: BBC] Several times, the BBC reports that Building 7 of the World Trade Center has collapsed, when it is in fact still standing. At 4:54 p.m., its domestic television news channel, BBC News 24, reports, “We’re now being told that yet another enormous building has collapsed… it is the 47-story Salomon Brothers building [i.e. WTC 7].” Three minutes later, its international channel, BBC World, reports, “We’ve got some news just coming in actually that the Salomon brothers building in New York right in the heart of Manhattan has also collapsed.” Then, at about 5:10 p.m., BBC World repeats the claim: “I was talking a few moments ago about the Salomon building collapsing and indeed it has… it seems this wasn’t the result of a new attack but because the building had been weakened during this morning’s attack.” Yet WTC 7 does not collapse until 5:20 p.m., over 25 minutes after the BBC first reported it (see (5:20 p.m.) September 11, 2001). The BBC’s live shot even shows the building still standing in the background, while its collapse is being reported. When these reports come to light early in 2007, Richard Porter, the head of news for BBC World, will suggest the error was due to the “confusing and chaotic situation on the ground” on 9/11. [BBC, 3/2/2007] Starting around 4:15 p.m., CNN and other news outlets had been reporting that WTC 7 was in danger of collapsing or may already have collapsed (see (4:15 p.m.-4:27 p.m.) September 11, 2001).

(5:20 p.m.) September 11, 2001: WTC Building 7 Collapses; Cause Remains Unclear

A four-image progression of photos showing World Trade Center Building 7 collapsing down into its footprint. [Source: unknown] (click image to enlarge) Building 7 of the World Trade Center complex, a 47-story tower, collapses. No one is killed. [CNN, 9/12/2001; WASHINGTON POST, 9/12/2001; MSNBC, 9/22/2001; ASSOCIATED PRESS, 8/21/2002] It collapses in 6.6 seconds, which is just 0.6 of a second longer than it would have taken a free-falling object dropped from its roof to hit the ground. [DESERET MORNING NEWS, 11/10/2005] Many questions will arise over the cause of its collapse in the coming months and years. Building 7, which was not hit by an airplane, is the first modern, steel-reinforced high-rise to collapse because of fire. [CHICAGO TRIBUNE, 11/29/2001; STANFORD REPORT, 12/5/2001; NEW YORK TIMES, 3/2/2002] Some will later suggest that the diesel fuel stored in several tanks on the premises may have contributed to the building’s collapse. The building contained a 6,000-gallon tank between its first and second floors and another four tanks, holding as much as 36,000 gallons, below ground level. There were also three smaller tanks on higher floors. [CHICAGO TRIBUNE, 11/29/2001; NEW YORK TIMES, 3/2/2002; NEW YORK OBSERVER, 3/25/2002; FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 1-17] However, the cause of the collapse is uncertain. A 2002 government report will conclude: “The specifics of the fires in WTC 7 and how they caused the building to collapse remain unknown at this time. Although the total diesel fuel on the premises contained massive potential energy, the best hypothesis has only a low probability of occurrence.” [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. 1-17] Some reports indicate that the building may have been deliberately destroyed. Shortly after the collapse, CBS News anchor Dan Rather comments that the collapse is “reminiscent of… when a building was deliberately destroyed by well-placed dynamite to knock it down.” [CBS NEWS, 9/11/2001] And moments after the collapse, MSNBC’s Brian Williams joins David Restuccio, an FDNY lieutenant, by phone to ask him about the collapse. “You guys knew this was coming all day?” asks Williams. Restuccio replies: “We had heard reports that the building was unstable, and that it would eventually need to come down on its own, or it would be taken down. I would imagine it came down on its own.” Restuccio does not explain what he means by “it would be taken down.” [MSNBC, 9/11/2001] Entity Tags: Dan Rather, World Trade Center, David Restuccio Timeline Tags: Complete 911 Timeline, 9/11 Timeline

Shortly After September 11, 2001: City Officials Make Decision to Scrap Remaining WTC Steel

Michael Burton. [Source: PBS] Following the World Trade Center collapses, a decision is made to quickly transport the remaining structural steel to scrap yards, to be shipped abroad and melted down for reuse. Consequently, virtually all of it is disposed of before investigators trying to assess why the WTC collapsed can examine it. Michael Burton and other officials at the Department of Design and Construction—the New York City agency overseeing the cleanup operation (see (September 11, 2001-May 2002))—are responsible for making this decision. Burton clears it with Richard Tomasetti of Thornton-Tomasetti Engineers, the prime consultant on the cleanup job. However, referring to the subsequent WTC investigation by the National Institute of Standards and Technology (see August 21, 2002), Tomasetti will later admit that had he known the direction that investigations into the collapses would take, he would have taken a different stand. [LANGEWIESCHE, 2002, PP. 30; GLANZ AND LIPTON, 2004, PP. 330 AND 396] Authors and New York Times reporters James Glanz and Eric Lipton write that Michael Burton, “who had become the effective czar for the cleanup job, had made it clear that he cared very little about engineering subtleties like the question of why the towers first stood, then collapsed on September 11. ‘We know why they fell,’ he said. ‘Because they flew two planes into the towers.’ But he was deeply immersed in the details of hauling steel out of the debris pile.” [GLANZ AND LIPTON, 2004, PP. 299] Much of the WTC steel will be shipped to India, China, and other Asian countries for recycling (see September 12-October 2001).

September 12, 2001: FEMA Assembles Team to Analyze WTC Collapses, but Investigation Is Severely Hampered

W. Gene Corley. [Source: ASCE] The Federal Emergency Management Agency (FEMA) and its contractor, Greenhorne and O’Mara, Inc., from Greenbelt, Maryland, begin putting together a Building Performance Assessment Team (BPAT), to conduct a formal analysis of the World Trade Center collapses, and produce a report of its findings. FEMA routinely deploys such teams following disasters, like floods or hurricanes. The 23-member BPAT team set up at the WTC collapse site is assembled by the American Society of Civil Engineers (ASCE), and headed by Dr. W. Gene Corley of Construction Technologies Laboratories in Skokie, Illinois. Corley was previously the principal investigator for FEMA’s study of the Murrah Building, in Oklahoma City in 1995. [NEW YORKER, 11/12/2001] BPAT team members are based nationwide and have to communicate with each other mostly by phone, as they continue with their regular jobs. While some of them are being paid for their efforts, others are working on the investigation voluntarily. They are told not to speak with reporters, under threat of dismissal from the team, supposedly because of the delicacy of the subject with which they are dealing. The BPAT team receives $600,000 of funding from FEMA, plus approximately $500,000 in ASCE in-kind contributions. [NEW YORK TIMES, 12/25/2001; ASSOCIATED PRESS, 1/14/2002; US CONGRESS, 3/6/2002] The team will have great difficulty accessing the collapse site and evidence they want to see (see March 6, 2002). They will be unable to get FEMA to obtain such basic data as detailed blueprints of the WTC buildings. FEMA will also refuse to allow them to make appeals to the public for photos and videos of the towers that might aid their investigation. Bureaucratic restrictions will often prevent them from making forensic inspections at Ground Zero, interviewing witnesses, or getting important evidence, like recorded distress calls from people who were trapped in the towers. [GLANZ AND LIPTON, 2004, PP. 330] The end product of their investigation is the FEMA World Trade Center Building Performance Study, released in May 2002 (see May 1, 2002).

September 12-14, 2001: Gruesome Remains Found at Ground Zero, but Supposedly No Black Boxes

John McCole [Source: Robson Books] Some gruesome remains are discovered in the World Trade Center ruins: Investigators find a pair of severed hands bound together with plastic handcuffs on a nearby building. They are believed to have belonged to a flight attendant. [NEWSDAY, 9/15/2001] Honorary firefighter Michael Bellone and two other recovery workers discover the body of an attendant from American Airlines Flight 11. Reportedly, the men’s digging efforts reveal “a blue skirt, then one side of a body, and finally a pair of wings still attached to the lapel of a woman’s jacket.” [SWANSON, 2003, PP. 140; DAILY STANDARD (GRAND LAKE), 9/11/2006] Other reports describe the discovery of the body of a flight attendant with her hands bound. Presumably they are referring to the same remains. [GUARDIAN, 9/13/2001; NEW YORK TIMES, 9/15/2001] There are reports of whole rows of seats with passengers in them being found, as well as much of the cockpit of one of the planes, complete with the body of a suspected hijacker. Police cannot confirm these reports. [ANANOVA, 9/13/2001; GUARDIAN, 9/13/2001; NEW YORK TIMES, 9/15/2001] Fire Lieutenant John McCole sees a body bag with a tag on it saying, “Possible Perp—pilot.” McCole later comments, “I found it pretty amazing that someone’s body could remain so intact after crashing through a skyscraper into the middle of an inferno.” [MCCOLE, 2002, PP. 57] Yet, contradicting the claim that a hijacker’s body was found, only in February 2003 are the remains of two hijackers identified (see Late February 2003). While all of these bodies and plane parts are supposedly found, it will be claimed that none of the four black boxes for the two aircraft that hit the WTC are ever found. A National Transportation Safety Board spokesperson later says: “It’s extremely rare that we don’t get the recorders back. I can’t recall another domestic case in which we did not recover the recorders.” [CBS NEWS, 2/23/2002] The black boxes are considered “nearly indestructible,” are placed in the safest parts of the aircraft, and are designed to survive impacts much greater than the WTC impact. They can withstand heat of up to 2,000 degrees Fahrenheit for one hour, and can withstand an impact of an incredible 3,400 G’s. [ABC NEWS, 9/17/2001] However, in 2004, it will be reported that some of the black boxes are found in the weeks after 9/11, but their discovery is kept secret (see October 2001).

September 12-October 2001: Steel Debris From WTC Shipped Out of US for Recycling

Steel beams from the WTC were already being removed and recycled on September 20, 2001. [Source: Associated Press] In the month following 9/11, a significant amount of the steel debris from the WTC collapses is removed from the rubble pile, cut into smaller sections, and either melted at a recycling plant or shipped out of the US. [US CONGRESS, 3/6/2002] Each of the Twin Towers contained 78,000 tons of recyclable steel. Much of this is shipped to India, China, and other Asian countries, where it will be melted down and reprocessed into new steel products. Asian companies are able to purchase the steel for just $120 per ton, compared, for example, to a usual average price of $150 per ton in China. Industry officials estimate that selling off the steel and other metals from the WTC for recycling could net a few tens of million dollars. [NEW YORK TIMES, 10/9/2001; REUTERS, 1/21/2002; REUTERS, 1/22/2002; EASTDAY, 1/24/2002; CORPWATCH, 2/6/2002] 9/11 victims’ families and some engineers are angered at the decision to quickly discard the steel, believing it should be examined to help determine how the towers collapsed. A respected fire fighting trade magazine comments, “We are literally treating the steel removed from the site like garbage, not like crucial fire scene evidence.” [FIRE ENGINEERING, 1/2002] Rep. Joseph Crowley (D) will later call the loss of this evidence “borderline criminal.” By March 2002, 150 pieces of steel from the WTC debris will have been identified by engineers for use in future investigations (see March 6, 2002). [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. D-13] A study by the National Institute of Standards and Technology (NIST), which commences in August 2002 [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 8/21/2002; ASSOCIATED PRESS, 8/21/2002], will have 236 pieces of recovered steel available to it. Of these, 229 pieces are from WTC 1 and 2, representing “roughly 0.25 percent to 0.5 percent of the 200,000 tons of structural steel used in the construction of the two towers.” [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 85 ] New York Mayor Mike Bloomberg defends the decision to quickly get rid of the WTC steel, saying, “If you want to take a look at the construction methods and the design, that’s in this day and age what computers do. Just looking at a piece of metal generally doesn’t tell you anything.” Officials in the mayor’s office decline to reply to requests by the New York Times regarding who decided to have the steel recycled.

September 12, 2001-September 2005: Weight of WTC Towers in Dispute

Ronald Hamburger, a member of NIST’s WTC team and advocate of the ‘piledriver’ theory. [Source: National Council of Structural Engineers' Associations] After 9/11, the scientists investigating the WTC collapse give very different figures for the buildings’ weight. Some sources say that each building weighed 500,000 tons. For example, MIT professor Thomas Eager writes, “The total weight of each tower was about 500,000 t.” [SCIENTIFIC AMERICAN, 10/9/2001; EAGAR AND MUSSO, 12/2001; FRANK GREENING, 2/16/2006, PP. 23 ; PBS, 8/2006] However, the National Institute of Standards and Technology (NIST) states that the buildings weighed only 250,000 tons each. [NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 32 ] One theory explaining the building’s total collapse is that the upper section acts as a “piledriver” and smashes through the floors below it. [BBC, 9/13/2001; STANFORD REPORT, 12/5/2001] The heavier the upper block above the impact zone, the more likely it is to be able to destroy the other floors as it falls.

September 12, 2001-September 2005: Duration of WTC Collapse in Dispute Following the attacks, there is no agreement on the speed with which the Twin Towers of the World Trade Center collapsed on 9/11 (see 9:59 a.m. September 11, 2001 and 10:28 a.m. September 11, 2001). The 9/11 Commission says that the South Tower collapsed in “ten seconds” and the National Institute of Standards and Technology says that tops of the buildings came down “essentially in free fall.” [9/11 COMMISSION, 7/24/2004, PP. 305; NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005, PP. 146 ] In the dispute over the reason for the WTC’s collapse after 9/11, it is claimed that, if the towers fell in ten seconds, then this is evidence they were destroyed by explosives. For example, David Ray Griffin, a theologian and outspoken critic of commission’s report, writes, “For a 1,300-foot building, however, ten seconds is almost free-fall speed. But if each floor produced just a little resistance, so that breaking through each one took half a second, the collapse of all those floors—80 or 95 of them—would have taken 40 to 47 seconds. Can we really believe that the upper part of the buildings encountered virtually no resistance from the lower part?” [GRIFFIN, 2004, PP. 16] But according to Canadian scientist Frank Greening, who studies the Twin Towers’ collapse, the freefall time would be about 9.6 seconds, and he calculates that it takes longer for the buildings to fall—twelve to thirteen and a half seconds—and states this does not indicate that explosives were used.

September 12, 2001-February 2002: Witnesses See Molten Metal in the Remains at Ground Zero

A chunk of hot metal being removed from the North Tower rubble about eight weeks after 9/11. [Source: Frank Silecchia] In the weeks and months after 9/11, numerous individuals report seeing molten metal in the remains of the World Trade Center: Ken Holden, who is involved with the organizing of demolition, excavation and debris removal operations at Ground Zero, later will tell the 9/11 Commission, “Underground, it was still so hot that molten metal dripped down the sides of the wall from [WTC] Building 6.” [9/11 COMMISSION, 4/1/2003] William Langewiesche, the only journalist to have unrestricted access to Ground Zero during the cleanup operation, describes, “in the early days, the streams of molten metal that leaked from the hot cores and flowed down broken walls inside the foundation hole.” [LANGEWIESCHE, 2002, PP. 32] Leslie Robertson, one of the structural engineers responsible for the design of the WTC, describes fires still burning and molten steel still running 21 days after the attacks. [SEAU NEWS, 10/2001 ] Alison Geyh, who heads a team of scientists studying the potential health effects of 9/11, reports: “Fires are still actively burning and the smoke is very intense. In some pockets now being uncovered, they are finding molten steel.” [JOHNS HOPKINS PUBLIC HEALTH MAGAZINE, 2001] Ron Burger, a public health advisor who arrives at Ground Zero on September 12, says that “feeling the heat” and “seeing the molten steel” there reminds him of a volcano. [NATIONAL ENVIRONMENTAL HEALTH ASSOCIATION, 9/2003, PP. 40 ] Paramedic Lee Turner arrives at the World Trade Center site on September 12 as a member of a federal urban search and rescue squad. While at Ground Zero, he goes “down crumpled stairwells to the subway, five levels below ground.” There he reportedly sees, “in the darkness a distant, pinkish glow—molten metal dripping from a beam.” [US NEWS AND WORLD REPORT, 9/12/2002] According to a member of New York Air National Guard’s 109th Air Wing, who is at Ground Zero from September 22 to October 6: “One fireman told us that there was still molten steel at the heart of the towers’ remains. Firemen sprayed water to cool the debris down but the heat remained intense enough at the surface to melt their boots.” [NATIONAL GUARD MAGAZINE, 12/2001] New York firefighters recall “heat so intense they encountered rivers of molten steel.” [NEW YORK POST, 3/3/2004] As late as five months after the attacks, in February 2002, firefighter Joe O’Toole sees a steel beam being lifted from deep underground at Ground Zero, which, he says, “was dripping from the molten steel.” [KNIGHT RIDDER, 5/29/2002] Steven E. Jones, a physics professor from Utah, later will claim this molten metal is “direct evidence for the use of high-temperature explosives, such as thermite,” used to deliberately bring down the WTC towers. [MSNBC, 11/16/2005] He will say that without explosives, a falling building would have “insufficient directed energy to result in melting of large quantities of metal.” [DESERET MORNING NEWS, 11/10/2005] There is no mention whatsoever of the molten metal in the official reports by FEMA, NIST, or the 9/11 Commission. [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002; 9/11 COMMISSION, 7/24/2004; NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY, 9/2005 ] But Dr. Frank Gayle, who leads the steel forensics aspects of NIST’s investigation of the WTC collapses, is quoted as saying: “Your gut reaction would be the jet fuel is what made the fire so very intense, a lot of people figured that’s what melted the steel. Indeed it didn’t, the steel did not melt.” [ABC NEWS 7 (NEW YORK), 2/7/2004] As well as the reports of molten metal, data collected by NASA in the days after 9/11 finds dozens of “hot spots” (some over 1,300 degrees) at Ground Zero (see September 16-23, 2001).

(September 11, 2001-May 2002): Little-Known City Agency Takes Charge of Ground Zero Cleanup Operation

Kenneth Holden. [Source: Public domain] The New York City agency that oversees the Ground Zero cleanup operation following the 9/11 attacks is the Department of Design and Construction (DDC). [GLANZ AND LIPTON, 2004, PP. 299] This obscure 1,300-man bureaucracy is normally responsible for overseeing municipal construction contracts, such as street repairs and jails. Its two top officials are Kenneth Holden and his lieutenant, Michael Burton. [LANGEWIESCHE, 2002, PP. 9] Burton is in lower Manhattan the morning of 9/11, instead of in his office in Queens, for a meeting at City Hall, just a few blocks away from the World Trade Center. [ENGINEERING NEWS-RECORD, 4/22/2002] That afternoon, he meets Holden and together they begin organizing the cleanup operation. By 5:30 p.m., the group of workers they have assembled gains permission to explore the WTC ruins. Under Burton’s direction, the team of “unbuilders” subsequently undertakes what journalist William Langewiesche describes as “the most aggressive possible schedule of demolition and debris removal.” Yet this appears to go against established procedures. On previous occasions the standard emergency response to natural or man-made disasters in the US, such as the 1995 Oklahoma City bombing, was to rapidly nationalize efforts on the ground, under the direction of FEMA and the Army Corps of Engineers. [LANGEWIESCHE, 2002, PP. 66, 90, 94, 146] New York’s official emergency plans, which were written before 9/11, in fact require the Department of Sanitation to remove debris after a building collapse. A mid-level official who was involved in writing the latest plans mentions a week after 9/11 that she doesn’t even know quite what the DDC is. DDC’s only previous experiences of dealing with emergencies are a sinking EMS station in Brooklyn, caused by a water leak, and a structural failure at Yankee Stadium. According to Langewiesche, there is no specific moment when Holden and Burton are placed in charge of the Ground Zero cleanup effort. “Rather, there was a shift of power in their direction that was never quite formalized and, indeed, was unjustified by bureaucratic logic or political considerations.” Reportedly, at some point, Mayor Rudolph Giuliani made a “back-room decision to scrap the organization charts, to finesse the city’s own Office of Emergency Management (OEM), and to allow the DDC to proceed.” [LANGEWIESCHE, 2002, PP. 66, 88 AND 118; ENGINEERING NEWS-RECORD, 4/22/2002] The Ground Zero cleanup operation officially ends in May 2002.

(September 12, 2001-May 2002): Recovery Workers Find WTC Pulverized to Dust from Collapses Workers involved in the cleanup at Ground Zero find that much of the World Trade Center towers and their contents have been pulverized to dust. Charlie Vitchers, a construction superintendent who oversees the operation, says, “Apart from recoveries, we didn’t find one thing. Nothing. Not even a file cabinet.… As we were working on the pile, people were saying, ‘We’re not finding anything.’” He adds, “We weren’t going to find anything that was made out of wood. But you think we would have found a computer.… We found cell phones. We found shoes. But with regard to furniture, nothing, not a thing, not a desk, not a wall panel.… [F]or the most part there was nothing in the pile of debris that was recognizable.” Crane operator Bobby Gray says, “I don’t remember seeing carpeting or furniture. You’d think a metal file cabinet would make it, but I don’t remember seeing any, or phones, computers, none of that stuff. There were areas where there were no fires, which is not to say that they didn’t experience tremendous heat anyway. But even in areas that never burned we didn’t find anything.” He comments, “It was just so hard to comprehend that everything could have been pulverized to that extent. How do you pulverize carpet or filing cabinets?” [STOUT, VITCHERS, AND GRAY, 2006, PP. 143-144] According to Greg Meeker of the US Geological Survey, “Six million sq ft of masonry, 5 million sq ft of painted surfaces, 7 million sq ft of flooring, 600,000 sq ft of window glass, 200 elevators, and everything inside came down as dust” when the towers collapsed. “The only thing that didn’t get pulverized was the WTC towers’ 200,000 tons of structural steel.” [CHEMICAL AND ENGINEERING NEWS, 10/20/2003] Some people will later claim that this complete pulverization of the WTC is evidence of the towers having been brought down deliberately, using explosives.

September 16, 2001: EPA Misleads Public about Health Risks at WTC Site

Smoke from the WTC tower collapses covers lower Manhattan on the day of 9/11, and for days afterward. [Source: ABC News/ Associated Press] The Environmental Protection Agency (EPA) and Occupational Safety and Health Administration (OSHA) release a joint statement asserting that the air in downtown New York City is safe to breathe. “New samples confirm previous reports that ambient air quality meets OSHA standards and consequently is not a cause for public concern,” the agencies claim. [ENVIRONMENTAL PROTECTION AGENCY, 9/16/2001] However, the government’s statements are based on ambient air quality tests using outdated technologies. [ST. LOUIS POST-DISPATCH, 1/14/2002] Furthermore, it will later be learned that the press release was heavily edited under pressure from the White House’s Council on Environmental Quality (CEQ). Critical passages in the original draft were either deleted or modified to downplay public health risks posed by contaminants that were released into the air during the collapse of the World Trade Center. [ENVIRONMENTAL PROTECTION AGENCY, 8/21/2003 ; NEWSDAY, 8/26/2003] In late October, the New York Daily News will obtain internal EPA documents containing information that had been withheld from the public. One document says that “dioxins, PCBs, benzene, lead, and chromium are among the toxic substances detected… sometimes at levels far exceeding federal levels.” [NEW YORK DAILY NEWS, 10/26/2001] Later, in October, it will be reported that thousands of rescue workers and residents are experiencing respiratory problems that experts attribute to the toxic smoke flume and ultra fine dust.

September 19-October 2001: Structural Engineer Finds Evidence of Extreme Temperatures at WTC

Dr. Abolhassan Astaneh-Asl examines steel from the World Trade Center. [Source: University of California, Berkeley] An engineer investigating the remains of the World Trade Center sees melted girders and other evidence that the towers experienced extreme temperatures on 9/11. Dr. Abolhassan Astaneh-Asl is a professor of civil and environmental engineering at the University of California, Berkeley. He specializes in studying structural damage done by earthquakes and terrorist bombings. [CHRONICLE OF HIGHER EDUCATION, 12/7/2001; CBS NEWS, 3/11/2002] He arrives in New York on September 19 to conduct a two-week scientific reconnaissance of the collapsed towers, hoping to gain an understanding of how they had come down. His project is one of eight financed by the National Science Foundation to study the WTC disaster. [NEW YORK TIMES, 10/2/2001; BERKELEYAN, 10/3/2001; US CONGRESS. HOUSE. COMMITTEE ON SCIENCE, 3/6/2002] He examines numerous pieces of steel taken from Ground Zero. [CHRONICLE OF HIGHER EDUCATION, 12/7/2001] Astaneh-Asl will describe the WTC as “the best-designed building I have ever seen.” [SAN FRANCISCO CHRONICLE, 10/22/2001] Yet he notices unusual warping and other damage in its remaining steel: At a recycling center in New Jersey, he sees 10-ton steel beams from the towers that look “like giant sticks of twisted licorice.” [CHRONICLE OF HIGHER EDUCATION, 12/7/2001] He shows the San Francisco Chronicle a “banana-shaped, rust-colored piece of steel” that has “twisted like toffee during the terrorist attack.” [SAN FRANCISCO CHRONICLE, 10/22/2001] He later recalls, “I saw melting of girders in [the] World Trade Center.” [PBS, 5/10/2007] He notes that steel has bent at several connection points that had joined the floors of the WTC to the vertical columns. He describes the connections as being smoothly warped, saying, “If you remember the Salvador Dali paintings with the clocks that are kind of melted—it’s kind of like that.” He adds, “That could only happen if you get steel yellow hot or white hot—perhaps around 2,000 degrees.” [CHRONICLE OF HIGHER EDUCATION, 12/7/2001] Astaneh-Asl says that steel flanges have been reduced “from an inch thick to paper thin.” [BERKELEYAN, 10/3/2001] He finds a foot-long twisted shard of steel that is “like a piece of bread, but it was high-strength steel.” He comments, “I haven’t seen anything like this [before].” [BERKELEY DAILY PLANET, 10/20/2001] He finds “severely scorched [steel] members from 40 or so floors below the points of impact [by the planes].” He believes this is the result of the planes having destroyed the elevator walls, thereby allowing burning jet fuel to pour down into the building, igniting fires hundreds of feet below the impact floors. [CBS NEWS, 3/12/2002] He says that, in some places, the fireproofing used to protect the WTC steel has “melted into a glassy residue.” [NEW YORK TIMES, 10/2/2001] Astaneh-Asl sees a charred I-beam from WTC Building 7, which collapsed late in the afternoon of 9/11. “The beam, so named because its cross-section looks like a capital I, had clearly endured searing temperatures. Parts of the flat top of the I, once five-eighths of an inch thick, had vaporized.” [NEW YORK TIMES, 10/2/2001] Other individuals will report seeing molten metal in the remains of the World Trade Center in the weeks and months after 9/11 (see September 12, 2001-February 2002), and data collected by NASA reveals dozens of “hot spots” (some over 1,300 degrees Fahrenheit) at Ground Zero (see September 16-23, 2001). But Thomas Eagar—an engineering professor at the Massachusetts Institute of Technology—later comments that the “temperature of the fire at the WTC [on 9/11] was not unusual, and it was most definitely not capable of melting steel.” [EAGAR AND MUSSO, 12/2001] Yet Astaneh-Asl will later put forward the “tentative” conclusion, “The collapse of the [Twin Towers] was most likely due to the intense fire initiated by the jet fuel of the planes and continued due to burning of the building contents.” [ASTANEH-ASL, 11/30/2003 ] Astaneh-Asl is a member of the team assembled by the American Society of Civil Engineers to investigate the World Trade Center site after 9/11 (see September 12, 2001), though he will resign from this because he disagrees with its decision to keep findings secret until the initial inquiry has been completed.

(September 25, 2001 and after): Ground Zero Workers Find Compressed Floors and Shattered Core Columns of WTC Two weeks after 9/11, engineers Pablo Lopez and Andrew Pontecorvo are walking in the B2 basement level at the ruins of the World Trade Center, towards where the North Tower stood. They discover a “solid, rocklike mass where the basement levels of the tower had been,” and see “the recognizable traces of twenty floors, very much like geologic strata revealed by a road cut, compressed into a ten-foot vertical span. In one place, the steel decks of half a dozen floors protruded like tattered wallpaper, so close together that they were almost touching where they were bent downward at the edge. Nothing between the decks was recognizable except as a rocky, rusty mishmash. In a few places what might have been carbonized, compressed stacks of paper stuck out edgewise like graphite deposits.” As New York Times reporters James Glanz and Eric Lipton describe, Lopez and Pontecorvo have found “where the vanished floors [of the tower] had gone. They had not just fallen straight down. The forces had been so great and the floors so light that they had simply folded up like deflated balloons.” Furthermore, they see the massive core columns of the tower, which are over two feet wide and made of four-inch thick steel plate, appearing to have suffered “a compound fracture: the upper sections looked as if they had been kicked, with incalculable fury, about a foot south of the sections they were resting on.” Lopez remarks, “Can you imagine the force?” [GLANZ AND LIPTON, 2004, PP. 292-293] At some later time, ironworker Danny Doyle, who is also working at Ground Zero, finds that floors of the South Tower have been compressed into a formation like what happened with the North Tower’s. He discovers “a distinct mound of debris set into the pile, about six feet high, with strands of wire and pieces of rebar sticking out. It looked like layers of sediment that had turned into rock and been lifted up on some mountainside.… Here were ten stories of the South Tower, compacted into an area of about six feet.” [GLANZ AND LIPTON, 2004, PP. 310] Entity Tags: Danny Doyle, Pablo Lopez, Andrew Pontecorvo, World Trade Center Timeline Tags: Complete 911 Timeline, 9/11 Timeline

Late September 2001-November 26, 2001: Theft of WTC Steel Leads to Tight Security Measures The New York Police and FBI are investigating the theft of over 250 tons of steel from the remains of the collapsed WTC towers. Apparently, the steel was hauled away by trucks involved in the official clear-up operation (see September 12-October 2001), but instead of being taken to Fresh Kills—the FBI-controlled dump on Staten Island where it was intended to go—the steel was driven to three independently-owned scrapyards, two in New Jersey and one on Long Island. The London Telegraph says the scrap metal value of the stolen steel would have been roughly $17,500. Investigators believe the theft was organized by one of New York’s Mafia families. [DAILY TELEGRAPH, 9/29/2001] Consequently, on November 26, 2001, the city initiates use of an in-vehicle Global Positioning System (GPS), to monitor the locations of nearly 200 trucks removing steel from the WTC collapse site, at a cost of $1,000 per unit. This system sends out alerts if any truck travels off course or arrives late at its destination. One driver involved with the clear-up operation is subsequently dismissed simply for taking an extended lunch break.

October 2001: Three of Four Black Boxes from WTC Crashes Secretly Found?

A poster to help law enforcement officers locate the missing “black boxes” in the WTC debris. [Source: FBI/Smithsonian Institution] According to two men who work extensively in the wreckage of the World Trade Center, three of the four black boxes from Flight 11 and Flight 175 are actually found during this month, but the public is not told. New York City Firefighter Nicholas DeMasi will mention the finding in a book published in 2003. He claims to drive federal agents on an all-terrain vehicle during their search and to see the found boxes himself. The Philadelphia Daily News will report on the story in 2004 when another rescue worker, volunteer Mike Bellone, backs up DeMasi’s account and claims to have seen one of the boxes as well. Spokesmen for the FBI and the New York City Fire Department will deny the claims of these two workers. [PHILADELPHIA DAILY NEWS, 10/28/2004] In 2005, it will be reported: “A source at the National Transportation Safety Board, the agency that has the task of deciphering the data from the black boxes retrieved from crash sites—including those that are being handled as crimes and fall under the jurisdiction of the FBI—says the boxes were in fact recovered and were analyzed by the NTSB. ‘Off the record, we had the boxes,’ the source says. ‘You’d have to get the official word from the FBI as to where they are, but we worked on them here.’” An NTSB spokesperson denies that the FBI ever gave them the boxes.

October 7, 2001: ISI Director Replaced at US Urging; Role in Funding 9/11 Plot Is One Explanation

The on-line Wall Street Journal article discussing the connections between Lt. Gen. Mahmood Ahmed, Saeed Sheikh, and Mohamed Atta. [Source: Public domain] ISI Director Lt. Gen. Mahmood Ahmed is replaced in the face of US pressure after links are discovered between him, Saeed Sheikh, and the funding of the 9/11 attacks. Mahmood instructed Saeed to transfer $100,000 into hijacker Mohamed Atta’s bank account prior to 9/11. This is according to Indian intelligence, which claims the FBI has privately confirmed the story. [PRESS TRUST OF INDIA, 10/8/2001; TIMES OF INDIA, 10/9/2001; INDIA TODAY, 10/15/2001; DAILY EXCELSIOR (JAMMU), 10/18/2001] The story is not widely reported in Western countries, though it makes the Wall Street Journal. [AUSTRALIAN, 10/10/2001; AGENCE FRANCE-PRESSE, 10/10/2001; WALL STREET JOURNAL, 10/10/2001] It is reported in Pakistan as well. [DAWN (KARACHI), 10/8/2001] The Northern Alliance also repeats the claim in late October. [FEDERAL NEWS SERVICE, 10/31/2001] In Western countries, the usual explanation is that Mahmood is fired for being too close to the Taliban. [LONDON TIMES, 10/9/2001; GUARDIAN, 10/9/2001] The Times of India reports that Indian intelligence helped the FBI discover the link, and says, “A direct link between the ISI and the WTC attack could have enormous repercussions. The US cannot but suspect whether or not there were other senior Pakistani Army commanders who were in the know of things. Evidence of a larger conspiracy could shake US confidence in Pakistan’s ability to participate in the anti-terrorism coalition.” [TIMES OF INDIA, 10/9/2001] There is evidence some ISI officers may have known of a plan to destroy the WTC as early as July 1999. Two other ISI leaders, Lt. Gen. Mohammed Aziz Khan and Lt. Gen. Muzaffar Usmani, are sidelined on the same day as Mahmood (see October 8, 2001). [FOX NEWS, 10/8/2001] Saeed had been working under Khan. The firings are said to have purged the ISI of its fundamentalists. However, according to one diplomat, “To remove the top two or three doesn’t matter at all. The philosophy remains.… [The ISI is] a parallel government of its own. If you go through the officer list, almost all of the ISI regulars would say, of the Taliban, ‘They are my boys.’” [NEW YORKER, 10/29/2001] It is believed Mahmood has been living under virtual house arrest in Pakistan (which would seem to imply more than just a difference of opinion over the Taliban), but no charges have been brought against him, and there is no evidence the US has asked to question him. [ASIA TIMES, 1/5/2002] He also has refused to speak to reporters since being fired [ASSOCIATED PRESS, 2/21/2002], and outside India and Pakistan, the story has only been mentioned infrequently in the media since. [SUNDAY HERALD (GLASGOW), 2/24/2002; LONDON TIMES, 4/21/2002] He will reemerge as a businessman in 2003, but still will not speak to the media (see July 2003).

December 2001: Scientific Journal Describes ‘Eutectic Mixture’ in WTC Steel

A sample of WTC steel eroded and corroded due to eutectic formations. [Source: FEMA] The Journal of the Minerals, Metals and Materials Society (JOM) reports that the examination of a beam from the remains of WTC Building 7—which collapsed late in the afternoon of 9/11 (see (5:20 p.m.) September 11, 2001)—has revealed “unexpected erosion” of the steel. The article states: “The formation of the eutectic mixture of iron oxide and iron sulfide lowers the temperature at which liquid can form in this steel. This strongly suggests that the temperatures in this region of the steel beam approached around 1,000°C, forming the eutectic liquid by a process similar to making a ‘blacksmith’s weld’ in a hand forge.” [BARNETT, BIEDERMAN, AND SISSON, 12/2001] The New York Times will call this “perhaps the deepest mystery uncovered in the investigation.” [NEW YORK TIMES, 2/2/2002] FEMA’s World Trade Center Building Performance Study, released in May 2002 (see May 1, 2002), will add that the same “unusual erosion patterns” have been observed in a sample of the remaining structural steel from one of the Twin Towers. It will state, “This sulfur-rich liquid penetrated preferentially down grain boundaries of the steel, severely weakening the beam and making it susceptible to erosion.” FEMA is unable to explain this phenomenon, saying, “The severe corrosion and subsequent erosion… are a very unusual event. No clear explanation for the source of the sulfur has been identified.… It is possible that this is the result of long-term heating in the ground following the collapse of the buildings. It is also possible that the phenomenon started prior to collapse and accelerated the weakening of the steel structure.” [FEDERAL EMERGENCY MANAGEMENT AGENCY, 5/1/2002, PP. C-1 - C-13] Despite FEMA’s call for further research, the National Institute of Standards and Technology (NIST) will make no mention of the eutectic formations in its final report into the WTC collapses, released in late 2005, following its three-year investigation.

December 25, 2001: Experts: WTC Collapse Investigation Inadequate The New York Times reports that “some of the nation’s leading structural engineers and fire-safety experts” believe the investigation into the collapse of the WTC is “inadequate” and “are calling for a new, independent and better-financed inquiry that could produce the kinds of conclusions vital for skyscrapers and future buildings nationwide.” Experts critical of the investigation include “some of those people who are actually conducting it.” They point out that the current team of 20 or so investigators has no subpoena power, inadequate financial support, and little staff support. Additionally, it has been prevented from interviewing witnesses and frequently prevented from examining the disaster site, and has even been unable to obtain basic information like detailed blueprints of the buildings that collapsed. The decision to recycle the steel columns, beams, and trusses from the WTC rapidly in the days immediately after 9/11 means definitive answers may never be known. [NEW YORK TIMES, 12/25/2001] Incredibly, some of the steel is reforged into commemorative medallions selling for $30 apiece.
