8:25 a.m. September 11, 2001: Boston Center Starts Notifying Chain of Command Boston flight control begins notifying the chain of command that a suspected hijacking of Flight 11 is in progress. Those notified include the center’s own facility manager, the FAA’s New England Regional Operations Center (ROC) in Burlington, Massachusetts, and the FAA Command Center in Herndon, Virginia (see 8:28 a.m. September 11, 2001). [FEDERAL AVIATION ADMINISTRATION, 9/17/2001 ; 9/11 COMMISSION, 8/26/2004, PP. 11 ] According to the 9/11 Commission, this is consistent with FAA protocol: “From interviews of controllers at various FAA centers, we learned that an air traffic controller’s first response to an aircraft incident is to notify a supervisor, who then notifies the traffic management unit and the operations manager in charge. The FAA center next notifies the appropriate regional operations center (ROC), which in turn contacts FAA headquarters.” [9/11 COMMISSION, 7/24/2004, PP. 458] But according to Ben Sliney, the national operations manager at the FAA’s Command Center, “the protocol was in place that the center that reported the hijacking would notify the military.… I go back to 1964, where I began my air traffic career, and they have always followed the same protocol.” [9/11 COMMISSION, 6/17/2004] Yet Boston Center supposedly will not contact NORAD about Flight 11 until about 12 minutes later (see (8:37 a.m.) September 11, 2001). Already about ten minutes have passed since controllers first noticed a loss of contact with Flight 11 (see (8:15 a.m.) September 11, 2001). Boston reportedly also contacts several other air traffic control centers about the suspected hijacking at this time (see 8:25 a.m. September 11, 2001).

8:28 a.m. September 11, 2001: FAA Command Center Informed of Flight 11 Hijacking, Establishes Teleconference between Air Traffic Control Centers

The FAA Command Center, the center of daily management of the US air traffic system. On 9/11 it is managed by Ben Sliney (not pictured here). [Source: CNN] The FAA’s Boston Center calls the FAA Command Center and says it believes Flight 11 has been hijacked and is heading toward the New York Center’s airspace. The Command Center immediately establishes a teleconference between the Boston, New York, and Cleveland air traffic control centers, so Boston can help the other centers understand what is happening, in case Flight 11 should enter their airspace. Minutes later, in line with the standard hijacking protocol, the Command Center will pass on word of the suspected hijacking to the FAA’s Washington headquarters (see 8:32 a.m. September 11, 2001). [9/11 COMMISSION, 7/24/2004, PP. 19; 9/11 COMMISSION, 8/26/2004, PP. 11 ; SPENCER, 2008, PP. 21] National Operations Manager Learns of Hijacking - A supervisor at the Command Center promptly passes on the news of the possible hijacking to Ben Sliney, who is on his first day as the national operations manager there. The supervisor says the plane in question is “American Flight 11—a 767 out of Boston for Los Angeles.” According to author Lynn Spencer, “Sliney flashes back to the routine for dealing with hijackings from the days when they were more common.” The procedure is to “[k]eep other aircraft away from the errant plane. Give the pilots what they need. The plane will land somewhere, passengers will be traded for fuel, and difficult negotiations with authorities will begin. The incident should resolve itself peacefully, although the ones in the Middle East, he recalls, often had a more violent outcome.” Apparently not expecting anything worse to happen, Sliney continues to the conference room for the daily 8:30 staff meeting there (see 8:30 a.m.-8:40 a.m. September 11, 2001). Command Center a 'Communications Powerhouse' - The FAA Command Center is located in Herndon, Virginia, 25 miles from Washington, DC. According to Spencer, it “is a communications powerhouse, modeled after NASA’s Mission Control. The operations floor is 50 feet wide and 120 feet long, packed with tiered rows of computer stations, and at the front, seven enormous display screens show flight trajectories and weather patterns.” The center has nearly 50 specialists working around the clock, planning and monitoring the flow of air traffic over the United States. These specialists work with airlines and air traffic control facilities to fix congestion problems and deal with weather systems.

8:32 a.m. September 11, 2001: FAA Headquarters Informed of Flight 11 Hijacking, but Does Not Contact the Pentagon to Request Assistance

FAA headquarters in Washington, DC. [Source: FAA] Four minutes after it is informed of the suspected hijacking of Flight 11 (see 8:28 a.m. September 11, 2001), the FAA Command Center in Herndon, Virginia, passes on word of the hijacking to the operations center at FAA headquarters in Washington, DC. The headquarters is apparently already aware of the hijacking, as the duty officer who speaks with the Command Center responds that security personnel at the headquarters have just been discussing it on a conference call with the FAA’s New England regional office. [9/11 COMMISSION, 7/24/2004, PP. 19; 9/11 COMMISSION, 8/26/2004, PP. 11 ] According to the 9/11 Commission, “FAA headquarters is ultimately responsible for the management of the national airspace system,” and the operations center there “receives notifications of incidents, including accidents and hijackings.” FAA headquarters has a hijack coordinator, who is “the director of the FAA Office of Civil Aviation Security or his or her designate.” Procedures require that, if a hijacking is confirmed, the hijack coordinator on duty is “to contact the Pentagon’s National Military Command Center (NMCC) and to ask for a military escort aircraft to follow the flight, report anything unusual, and aid search and rescue in the event of an emergency.” Yet, the Commission will state, although “FAA headquarters began to follow the hijack protocol,” it does “not contact the NMCC to request a fighter escort.” [9/11 COMMISSION, 7/24/2004, PP. 16-19] Mike Canavan, who would normally be the FAA’s hijack coordinator, is away in Puerto Rico this morning, and it is unclear who—if anyone—is standing in for him in this critical role (see 8:30 a.m. September 11, 2001).

(8:45 a.m.) September 11, 2001: Air Traffic Control Centers Receive False Bomb Threats? CNN reports that, while Flight 11 is heading toward the World Trade Center, “[S]ources say there were bomb threats called in to air traffic control centers adding to the chaos.” One center receiving such threats is the FAA’s Boston Center, which handles air traffic over New England and monitors flights 11 and 175. Cleveland Center, which will monitor Flight 93, receives similar threats. Whether other centers are threatened is unstated. According to Newsweek, “Officials suspect that the bomb threats were intended to add to the chaos, distracting controllers from tracking the hijacked planes.” [NEWSWEEK, 9/22/2001; CNN, 9/30/2001] Yet, just weeks after 9/11, the Washington Post will claim, “Federal aviation officials no longer believe that accomplices of the hijackers made phony bomb threats to confuse air traffic controllers on Sept. 11. Sources said reports of multiple threats were apparently the result of confusion during the early hours of the investigation and miscommunication in the Federal Aviation Administration.” [WASHINGTON POST, 9/27/2001] Entity Tags: Cleveland Air Route Traffic Control Center, Boston Air Route Traffic Control Center Timeline Tags: Complete 911 Timeline, 9/11 Timeline

9:03 a.m. September 11, 2001: Boston Center Tells FAA Regional Office that Hijackers Said ‘We Have Planes’; Office Suggests Notifying Military

Terry Biggio. [Source: Federal Aviation Administration] Over an FAA teleconference, Terry Biggio, the operations manager at the FAA’s Boston Center, reports to the FAA’s New England regional office the “We have some planes” comment apparently made by a Flight 11 hijacker at 8:24 a.m. (see 8:24 a.m. September 11, 2001). [9/11 COMMISSION, 8/26/2004, PP. 23 ; SPENCER, 2008, PP. 79-80] Because the Boston Center controller monitoring Flight 11 had not understood the communication, the center’s quality assurance specialist had been instructed to “pull the tape” of the transmission, listen to it carefully, and then report back. [9/11 COMMISSION, 7/24/2004, PP. 19] Biggio now reports to the New England region representative: “I’m gonna reconfirm with, with downstairs, but the, as far as the tape, Bobby seemed to think the guy said that ‘we have planes.’ Now, I don’t know if it was because it was the accent, or if there’s more than one [hijacked plane], but I’m gonna, I’m gonna reconfirm that for you, and I’ll get back to you real quick. Okay?” Another participant in the teleconference asks, “They have what?” and Biggio clarifies: “Planes, as in plural.… It sounds like, we’re talking to New York, that there’s another one aimed at the World Trade Center.… A second one just hit the Trade Center.” The New England region representative replies: “Okay. Yeah, we gotta get—we gotta alert the military real quick on this.” [9/11 COMMISSION, 6/17/2004; 9/11 COMMISSION, 7/24/2004, PP. 23] A manager at the FAA’s Command Center in Herndon, Virginia, is monitoring the teleconference, and so also learns of the “We have some planes” communication at this time (see 9:03 a.m. September 11, 2001). [SPENCER, 2008, PP. 79-80] At 9:05 a.m., Biggio will confirm for the New England region representative—with the Command Center listening in—that a hijacker said, “we have planes” (forgetting the “some”).

9:05 a.m. September 11, 2001: Air Space Closed over New York Area

Bruce Barrett. [Source: H. Darr Beiser / USA Today] The FAA’s New York Center declares “air traffic control zero” (“ATC zero”), which means that all air traffic is prevented from departing from, arriving at, or traveling through the center’s airspace until further notice. [USA TODAY, 8/13/2002; FRENI, 2003, PP. 18; 9/11 COMMISSION, 8/26/2004, PP. 24 ] According to author Lynn Spencer: “ATC zero is designed for situations in which an air traffic facility is completely incapable of handling aircraft due to a massive computer failure, power outage, or even a large enough weather system. The declaration pushes all their aircraft onto neighboring sectors, and any new airplanes from adjacent sectors are turned back, at the sector boundaries if necessary.” [SPENCER, 2008, PP. 68] The decision to declare ATC zero is made after the second plane hits the World Trade Center, confirming that the US is under terrorist attack. There are currently hundreds of aircraft in the skies around New York and the western Atlantic that the New York Center is responsible for. [ASSOCIATED PRESS, 8/12/2002] Bruce Barrett, a senior manager at the New York Center, announces, “We’re declaring ATC zero,” and Mike McCormick, the center’s air traffic control manager, approves the order. Several of the managers there then start informing air traffic controllers of the decision. Unprecedented Order - USA Today will report that this decision is unprecedented: “Controllers had gone to ‘air traffic control zero’ before, but only when their radar shut down or their radio transmitters went silent. The planes kept flying then, and controllers in other centers guided them. This time, ATC zero means something far more drastic. It means emptying the skies—something that has never been attempted. And not just the skies over Manhattan. Controllers must clear the air from southern New England to Maryland, from Long Island to central Pennsylvania—every mile of the region they control.… Controllers from Cleveland to Corpus Christi must reroute jets headed to the region and put some in holding patterns.” Accounts Conflict over Whether Center Seeks Permission - According to USA Today, McCormick and Barrett declare ATC zero without first seeking permission from higher-ups, because a “call to Washington could take minutes, and they aren’t sure they have that long.” [USA TODAY, 8/13/2002] But according to Lynn Spencer, a New York Center supervisor has already requested ATC zero in a call to the FAA’s Herndon Command Center. Ben Sliney, the Command Center’s national operations manager, assured the supervisor, “You take care of matters in your center and we will provide all the assistance necessary by stopping any further aircraft from entering your airspace.” [SPENCER, 2008, PP. 68] Entity Tags: Ben Sliney, New York Air Route Traffic Control Center, Lynn Spencer, Bruce Barrett, Mike McCormick Timeline Tags: Complete 911 Timeline, 9/11 Timeline

9:07 a.m. September 11, 2001: Boston Center Manager Wants Cockpit Security Warnings Sent to Aircraft After conferring with the FAA’s New England regional office and contacting representatives of the Air Transport Association, the FAA’s Boston Center decides to issue a Notice to Airmen, warning pilots to heighten cockpit security. [9/11 COMMISSION, 8/26/2004, PP. 24-25 ] Following the second attack on the World Trade Center, Terry Biggio, the operations manager at the Boston Center, is concerned that there may be additional attacks. He therefore asks a manager at the FAA’s New England regional office if warnings could be sent to airborne aircraft via “ACARS or something,” advising them to increase their cockpit security. [9/11 COMMISSION, 8/26/2004, PP. 24 ] (ACARS is an e-mail system that allows personnel on the ground to rapidly communicate with those in the cockpit of an aircraft. [9/11 COMMISSION, 8/26/2004, PP. 9 ] ) Biggio is particularly concerned about the need to warn airborne international flights that are scheduled to arrive at New York’s JFK International Airport. On the advice of a New England Region representative, Boston Center decides to contact Air Transport Association representatives through the FAA’s Herndon Command Center and ask them to formally request that airlines warn their aircraft to heighten cockpit security. According to the 9/11 Commission, though, Biggio is “[n]ot content to rely on the airlines to warn their aircraft,” and so decides that the Boston Center will issue a Notice to Airmen (“NOTAM”) to heighten cockpit security in light of the attacks in New York. [9/11 COMMISSION, 8/26/2004, PP. 24-25 ] The NOTAM system is the communication method used to define the rules of the day for air traffic controllers and pilots. With the status of equipment, airports, and rules changing frequently, the NOTAM system is used to distribute any changes to all pilots and controllers. [FRENI, 2003, PP. 86] Two or three minutes later, controllers at the Boston Center will contact all the aircraft in their airspace by radio and advise them to increase cockpit security (see 9:09 a.m.-9:10 a.m. September 11, 2001).

9:09 a.m.-9:10 a.m. September 11, 2001: Boston Center Controllers Give Cockpit Security Alert to All Their Aircraft Terry Biggio, the operations manager at the FAA’s Boston Center, instructs the air traffic controllers at his center to contact all aircraft in the center’s airspace by radio and inform them of the events taking place in New York. He tells the controllers to also advise the aircraft to heighten their cockpit security in light of these events. [9/11 COMMISSION, 7/24/2004, PP. 23; 9/11 COMMISSION, 8/26/2004, PP. 25 ] According to author Lynn Spencer, previously “No transmission of that kind has ever been made on air traffic control frequencies.” Controller Jim Ekins is the first to act. He announces over all the radio frequencies in the sector: “All aircraft! Due to recent events that have unfolded in the Boston sector, you are advised to increase cockpit security. Allow no entry to your cockpit!” According to Spencer, other controllers nearby overhear and realize: “Yes! That’s exactly what we need to tell them!” [SPENCER, 2008, PP. 98] The Boston Center air traffic controllers then immediately execute Biggio’s order, and give the warning to their aircraft. [9/11 COMMISSION, 8/26/2004, PP. 25 ] However, Spencer will write: “Communications with controllers are [usually] as dry as they come, and to many pilots this announcement is so out of their realm of understanding, training, and experience that it simply doesn’t make sense. It actually agitates some, who cannot help but view it as some new kind of ‘FAA bureaucratic bullsh_t.’” [SPENCER, 2008, PP. 99] Boston Center will subsequently ask the FAA’s Herndon Command Center to issue a similar cockpit security alert nationwide, but the Command Center apparently will not act on this request (see (9:15 a.m.) September 11, 2001). [9/11 COMMISSION, 7/24/2004, PP. 23] United Airlines will issue a company-wide order at 9:21 for its dispatchers to warn their flights to secure their cockpits (see 9:21 a.m. September 11, 2001).

9:19 a.m. September 11, 2001: FAA Concerned about Delta Flight 1989, Wants It to Increase Cockpit Security The FAA’s New England regional office calls the FAA’s Herndon Command Center, and asks it to tell Cleveland Center to contact Delta Air Lines Flight 1989 and advise it to use extra cockpit security. The reason the New England regional office makes this request is unclear. [9/11 COMMISSION, 7/24/2004, PP. 10] As the 9/11 Commission will describe, apparently in response to the request, “[A]t 9:19 the FAA… Command Center in Herndon ordered controllers to send a cockpit warning to Delta 1989 because, like American 11 and United 175, it was a transcontinental flight departing Boston’s Logan Airport.” [9/11 COMMISSION, 7/24/2004, PP. 455] Minutes earlier, the FAA’s Boston Center asked the Command Center to contact the nation’s FAA centers and instruct them to tell all airborne aircraft to increase their cockpit security (see (9:15 a.m.) September 11, 2001). The Command Center’s instruction to air traffic controllers about Delta 1989 is apparently an exception, as the 9/11 Commission will say it found “no evidence to suggest that the Command Center acted on this request.” [9/11 COMMISSION, 7/24/2004, PP. 23; 9/11 COMMISSION, 8/26/2004, PP. 25-26 ] Delta 1989 will subsequently be mistakenly reported as having been hijacked (see (9:28 a.m.-9:33 a.m.) September 11, 2001 and 9:39 a.m. September 11, 2001).

Space view of New York on 9/11/01 [Source: NASA] The commander of the International Space Station, Frank Culbertson, is informed of the 9/11 attacks by NASA’s ground control. The station is orbiting the earth at a distance of about 300 miles. In addition to Culbertson, the station is manned by two Russian cosmonauts, Vladimir Dezhurov and Mikhail Tyurin. Culbertson quickly determines that the station will soon fly over New England. He positions himself with video and photographic equipment to record what he can see from space. One of his pictures, apparently taken after the collapse of both towers, shows a plume of smoke rising tens of miles into the sky. Vladimir Dezhurov will later take part in a televised debate during which he will apparently express skepticism about the US government’s version of the attacks (see September 12, 2008).

(Before 10:06 a.m.) September 11, 2001: Fighters Trailing Flight 93 When It Crashes, According to Some Accounts; Other Accounts Contradict This Shortly after 9/11, the North American Aerospace Defense Command (NORAD) will say the nearest fighter jets to Flight 93 at the time it crashes are the F-16s from Langley Air Force Base that are flying a combat air patrol over Washington, DC (see (Between 9:49 a.m. and 11:00 a.m.) September 11, 2001). [NORTH AMERICAN AEROSPACE DEFENSE COMMAND, 9/18/2001; 9/11 COMMISSION, 8/26/2004, PP. 34 ] Other accounts will conflict over whether or not there are any fighter jets near Flight 93 when it goes down: Two days after the attacks, it will be reported that an unnamed New England air traffic controller has ignored a ban on controllers speaking to the media, and this controller claims “that an F-16 fighter closely pursued Flight 93.… [T]he F-16 made 360-degree turns to remain close to the commercial jet.” The controller adds that the fighter pilot “must’ve seen the whole thing.” He reportedly learned this from speaking to controllers who were closer to the crash. [ASSOCIATED PRESS, 9/13/2001; TELEGRAPH (NASHUA), 9/13/2001] Five days after the attacks, on September 16, CBS News will report that two F-16s are tailing Flight 93 and are within 60 miles of it when it goes down. [CBS NEWS, 9/16/2001; INDEPENDENT, 8/13/2002] But, also on September 16, Major General Paul Weaver, the director of the Air National Guard, will say that no military planes were sent after Flight 93. [SEATTLE TIMES, 9/16/2001] In April 2002, Anthony Kuczynski will tell the University of St. Thomas’s weekly newspaper that he had flown toward Pittsburgh alongside two F-16s on 9/11. He says he was piloting an E-3 Sentry AWACS plane, which has advanced radar and surveillance equipment that can be used to direct fighter jets to their targets. He was just about to intercept Flight 93 when it crashed. He says, “I was given direct orders to shoot down an airliner.” (E-3s are unarmed, so, if this account is accurate, the order presumably applied to the fighters Kuczynski was accompanying.) [ST. THOMAS AQUIN, 4/12/2002; US AIR FORCE, 11/20/2009] A year after the attacks, ABC News will report that the “closest fighters” to Flight 93 when it crashes “are two F-16 pilots on a training mission from Selfridge Air National Guard Base” near Detroit, Michigan. These are ordered after Flight 93, according to some accounts, even though they are unarmed. [ABC NEWS, 8/30/2002; ABC NEWS, 9/11/2002] However, other accounts will state that these jets are in fact ordered to intercept another aircraft, Delta 1989, or are simply told to return to their base (see (9:55 a.m.) September 11, 2001 and (9:56 a.m.-10:29 a.m.) September 11, 2001).

[MSNBC, 9/11/2002] Five years after 9/11, Bill Keaton, a Cleveland Center controller who tracked Flight 93 as it flew eastward (see (9:41 a.m.-10:06 a.m.) September 11, 2001), will be asked whether there were fighter jets in the vicinity of the plane when it crashed. He will reply, “[T]hat goes beyond the scope of what I can comment on.” (Air traffic controllers reportedly can lose their security clearances if they discuss the movements of military aircraft.)

(10:20 a.m.) September 11, 2001: Boston Center Controller Notices Unidentified Aircraft Approaching from East An air traffic controller at the FAA’s Boston Center is concerned about an unidentified aircraft flying in from the east, approaching Cape Cod. Colin Scoggins, the military liaison at the Boston Center in Nashua, New Hampshire, has noticed the large, slow-moving target on his radar screen. It is just off the coast and heading directly for Boston. Concerned as to what the aircraft is, he phones the Fleet Area Control and Surveillance Facility in Virginia Beach, Virginia. [SPENCER, 2008, PP. 242] The facility, known by its call sign, “Giant Killer,” is the Navy air traffic control agency that handles all over-water military operations. [NEW YORK TIMES, 2/10/1997; SPENCER, 2008, PP. 143] Scoggins says: “We have a large, slow-moving target approaching Cape Cod and heading for Boston. Do you have it? What is it?” The person at Giant Killer only replies, “We’re looking,” and then mentions, “We’ve got a fleet of ships heading toward the northeast and an Aegis cruiser [a high-tech warship] on the way.” Scoggins is worried that Giant Killer is unable to specifically identify the target he is seeing on his radar screen. It appears to be flying straight toward the Boston Center. He thinks to himself, “If I wanted to use airliners to attack a country, I would take out their air traffic control facilities!” Scoggins continues watching the suspicious aircraft on his radar screen. Shortly afterward, the Boston Center will be evacuated after the FAA’s New England regional office calls it and reports an unidentified aircraft heading toward the facility (see (Shortly After 10:20 a.m.) September 11, 2001). [SPENCER, 2008, PP. 242-243] This is apparently a different aircraft to the one Scoggins is tracking. [FEDERAL AVIATION ADMINISTRATION, 9/20/2001; FEDERAL AVIATION ADMINISTRATION, 3/21/2002 ] Whether the plane Scoggins is tracking is ever identified is unclear.

(Shortly After 10:20 a.m.) September 11, 2001: Boston Air Traffic Control Center Evacuated following Report of Airborne Threat The FAA’s Boston Center is evacuated after it receives a report that an unidentified aircraft is heading its way. [FEDERAL AVIATION ADMINISTRATION, 9/20/2001; USA TODAY, 8/11/2002; NEW HAMPSHIRE UNION LEADER, 9/11/2006; SPENCER, 2008, PP. 243] The Boston Center, located in Nashua, New Hampshire, manages air traffic above New England, and monitored Flight 11 and Flight 175 earlier on. [USA TODAY, 8/11/2002; ASSOCIATED PRESS, 8/12/2002] Employees there are already concerned because a large tractor-trailer has parked directly in front of their facility, on New Hampshire’s Route 3. State police have been called to get it away from there. Possible Airborne Threat Leads to Evacuation - The FAA’s New England regional office in Burlington, Massachusetts, now calls the Boston Center and reports that an unidentified aircraft is heading for the facility. In response to this potential threat, managers at the center immediately order the closure and evacuation of their building. They also declare “ATC zero,” which shuts down the Boston Center’s airspace (see (Shortly After 10:20 a.m.) September 11, 2001). Employees run from the building while managers try to decide which, if any, personnel should remain in the facility. According to Colin Scoggins, the center’s military liaison, “at this time we honestly felt that we were targeted and an impact was imminent.” Bomb Threat to Childcare Facility - Making matters worse, a bomb scare phone call is received at the center’s childcare facility, which is the employees’ usual evacuation point. Center managers therefore decide that everyone must leave the building. Employees are advised to go to either 11 Murphy Drive—an FAA administrative facility—or a nearby Holiday Inn. According to Scoggins, three or four Flight Service Data Processing System personnel remain in the basement of the Boston Center when it is evacuated, apparently because there is no paging system in their office on which they can receive the evacuation order. Evacuation Time Unclear - The time the evacuation takes place at is unclear. According to the account of author Lynn Spencer, it occurs some time shortly after 10:20 a.m. [FEDERAL AVIATION ADMINISTRATION, 9/20/2001; USA TODAY, 8/11/2002; SPENCER, 2008, PP. 242-243] At 10:34 a.m., John White, a manager at the FAA’s Command Center, reports that the Boston Center “has received a threat,” and is “going down to skeleton staffing.” [9/11 COMMISSION, 11/4/2003] A 10:52 a.m. entry in the log of the FAA headquarters’ teleconference will state that the Boston Center is “evacuating the building.” [FEDERAL AVIATION ADMINISTRATION, 3/21/2002 ] USA Today will report that the center is evacuated at “about 11 a.m.” Few Employees Return to Building - About 30 minutes to an hour after the building is evacuated, some of the center’s personnel will return to work. [FEDERAL AVIATION ADMINISTRATION, 9/20/2001; USA TODAY, 8/11/2002] By 12:16 p.m., the center is back in operation, but with only a skeleton staff. [FEDERAL AVIATION ADMINISTRATION, 3/21/2002 ] Suspicious Aircraft Only a Coast Guard Plane - As it turns out, the approaching aircraft that prompts the evacuation is just a Coast Guard plane. According to Scoggins, “We had already identified it.” [FEDERAL AVIATION ADMINISTRATION, 9/20/2001] The aircraft was noted in a 10:18 a.m. entry in the log of the FAA headquarters’ teleconference, which stated: “Aircraft 160 miles east of Nantucket is headed westbound toward Boston at a high rate of speed.” But a log entry five minutes later, at 10:23 a.m., noted that the aircraft “is identified as a Coast Guard flight from Nantucket.” [FEDERAL AVIATION ADMINISTRATION, 3/21/2002 ] Shortly before the Boston Center is alerted to this aircraft, Scoggins had been tracking what is apparently another unidentified target on his radar screen: a slow-moving large aircraft that is also flying toward the Boston Center from the east (see (10:20 a.m.) September 11, 2001). [SPENCER, 2008, PP. 242-243] The identity of that aircraft is unclear.

(Shortly After 10:20 a.m.) September 11, 2001: Boston Center Controller Contacts NEADS and Canadian Facility, Reports Center Evacuation and Airborne Threat

The Moncton Area Control Center. [Source: Nav Canada] Colin Scoggins, the military liaison at the FAA’s Boston Center, contacts NORAD’s Northeast Air Defense Sector (NEADS) and a Canadian air traffic control facility, to let them know that the Boston Center is shutting down its airspace and being evacuated, due to a possible airborne threat. Scoggins Does Not Immediately Evacuate - The Boston Center in Nashua, New Hampshire, has just received a call from the FAA’s New England regional office, alerting it to an unidentified aircraft heading its way. In response, the center’s managers ordered the evacuation of the facility (see (Shortly After 10:20 a.m.) September 11, 2001) and declared “ATC zero,” which completely shuts down the center’s airspace (see (Shortly After 10:20 a.m.) September 11, 2001). But while others leave the building, Scoggins stays behind to make two phone calls. Scoggins Calls Canadian Facility and NEADS - His first call is to the Moncton Center, which is the Canadian air traffic control facility that handles flights arriving from over the Atlantic. He tells a supervisor there, “We’re going to ATC zero and evacuating.” Scoggins then calls NEADS with the same information. He says: “I wanted to let you know, Boston Center has declared ATC zero and we are evacuating due to an airborne threat. It’s approaching Martha’s Vineyard and it’s coming our way.” Before hanging up, he gives NEADS the speed and coordinates of the approaching aircraft. Scoggins then heads out of the building. According to the account of author Lynn Spencer, Scoggins’s call prompts NEADS to immediately call Otis Air National Guard Base in Cape Cod, Massachusetts, and order it: “Get everything you’ve got in the air! Now!” (see (10:20 a.m.) September 11, 2001). FBI and SWAT Teams Surround Center - By the time Scoggins is outside the Boston Center, FBI and SWAT teams are surrounding the facility. Scoggins will later recall that he sees the “Nashua SWAT team in the parking lot with automatic weapons, [and] the FBI running with the audio tapes with Bob Jones [a quality assurance specialist at the Boston Center] by their side.” [FEDERAL AVIATION ADMINISTRATION, 9/20/2001; SPENCER, 2008, PP. 243-245] (The FBI reportedly arrived at the Boston Center “minutes after Flight 11 crashed into the World Trade Center,” and seized tape recordings of radio transmissions from the hijacked plane (see Soon after 8:46 a.m. September 11, 2001). [CHRISTIAN SCIENCE MONITOR, 9/13/2001] ) Scoggins Tracking Other Unidentified Plane - Before the Boston Center received the call from the FAA regional office about the approaching aircraft, Scoggins was tracking another unidentified target on his radar screen: a slow-moving aircraft also flying toward the center from the east (see (10:20 a.m.) September 11, 2001). Whether he alerts NEADS to that aircraft when he calls it is unclear.
