United Airline Flight 93:Timeline

September 11
(6:20 a.m.-7:48 a.m.) September 11, 2001: Hijackers Arrive at Airports and Board Flights; Computer Screening Program Fails to Stop Them All the alleged 9/11 hijackers reportedly check in at the airports from where they board Flights 11, 175, 77, and 93. [9/11 COMMISSION, 7/24/2004, PP. 1-4; 9/11 COMMISSION, 8/26/2004, PP. 27, 89, 93 ] Since 1998, the FAA has required air carriers to implement a program called the Computer Assisted Passenger Prescreening System (CAPPS). This identifies those passengers who might be a security risk, based upon suspicious behavior such as buying one-way tickets or paying with cash. CAPPS also randomly assigns some passengers to receive additional security scrutiny. If a particular passenger has been designated as a “selectee,” this information is transmitted to the airport’s check-in counter, where a code is printed on their boarding pass. At the airport’s security checkpoints, selectees are subjected to additional security measures. [US NEWS AND WORLD REPORT, 4/1/2002; 9/11 COMMISSION, 1/27/2004; US CONGRESS, 3/17/2004; 9/11 COMMISSION, 8/26/2004, PP. 2, 85 ] Their baggage is to be screened for explosives or held off the plane until they have boarded. Supposedly, the thinking behind this is that someone smuggling a bomb onto a plane won’t get onto that same flight. According to the 9/11 Commission, nine of the 19 hijackers are flagged by the CAPPS system before boarding Flights 11, 175, 77, and 93.

ZACARIAS MOUSSAOUI, A/K/A SHAQIL, A/K/A ABU KHALID AL SAHRAWI, DEFENDANT, 3/6/2006] In addition, Mohamed Atta was selected when he checked in at the airport in Portland, for his earlier connecting flight to Boston (see 5:33 a.m.-5:40 a.m. September 11, 2001). All of the hijackers subsequently pass through security checkpoints before boarding their flights.

(6:45 a.m.) September 11, 2001: Ziad Jarrah Makes Final Phone Call to Girlfriend in Germany About an hour before boarding Flight 93, Ziad Jarrah phones his girlfriend, Aysel Senguen, who is currently recovering from a minor operation in a hospital in Germany, where she lives. [LOS ANGELES TIMES, 10/23/2001; OBSERVER, 8/22/2004] Senguen will later recount, “[H]e was very brief. He said he loved me three times. I asked what was up. He hung up shortly afterwards.… It was so short and rather strange him saying that repeatedly.” [REUTERS, 11/19/2002; GUARDIAN, 11/20/2002] Some accounts say Jarrah makes this call from his hotel, the Days Inn in Newark. Other accounts claim he makes it from a payphone at the airport, although he does not actually check in there until later on, at 7:39 a.m. [PBS, 1/17/2002; 9/11 COMMISSION, 7/24/2004, PP. 532; OBSERVER, 8/22/2004; SUNDAY HERALD (GLASGOW), 8/22/2004; 9/11 COMMISSION, 8/26/2004, PP. 35 ] Entity Tags: Ziad Jarrah, Aysel Senguen Timeline Tags: 9/11 Timeline Category Tags: All Day of 9/11 Events, Flight UA 93, Ziad Jarrah

(7:00 a.m.-7:45 a.m.) September 11, 2001: Computer Screening Program Selects Some Hijackers; Fails to Stop Them Sometime during this period, the hijackers pass through airport security checkpoints at the various airports. The FAA has a screening program in place called the Computer Assisted Passenger Prescreening System (CAPPS). CAPPS automatically targets passengers for additional screening based on suspicious behavior such as buying one-way tickets or paying with cash. If a passenger is selected, their bags are thoroughly screened for explosives, but their bodies are not searched. [WASHINGTON POST, 1/28/2004] CAPPS selects three of the five Flight 11 hijackers. Since Waleed Alshehri checked no bags, his selection had no consequences. Wail Alshehri and Satam Al Suqami have their bags scanned for explosives, but are not stopped. No Flight 175 hijackers are selected. Only Ahmad Alhaznawi is selected from Flight 93. His bag is screened for explosives, but he is not stopped. The 9/11 Commission later concludes that Alhaznawi and Ahmed Alnami, also headed to Flight 93, have suspicious indicators and that they could have been linked to al-Qaeda upon inspection, but it has not been explained why or how. [9/11 COMMISSION, 1/27/2004; BALTIMORE SUN, 1/27/2004] Screening of the Flight 77 hijackers is described below. Entity Tags: Waleed M.

(7:03 a.m.-7:48 a.m.) September 11, 2001: Flight 93 Hijackers Check in at Airport and Board Plane; Only One Selected for Additional Screening According to the 9/11 Commission, between 7:03 a.m. and 7:39 a.m. the four alleged Flight 93 hijackers check in at the United Airlines ticket counter at Newark (New Jersey) Liberty International Airport. Only Ahmad Alhaznawi is selected for additional scrutiny by airport security under the FAA’s CAPPS program (see (6:20 a.m.-7:48 a.m.) September 11, 2001). The only consequence is that his checked bag is screened for explosives, and not loaded onto the plane until it is confirmed that he has boarded. [9/11 COMMISSION, 1/27/2004; 9/11 COMMISSION, 7/24/2004, PP. 4; 9/11 COMMISSION, 8/26/2004, PP. 35 ] On their way to boarding the plane, all four would pass through a security checkpoint, which has three walk-through metal detectors, two X-ray machines, and explosive trace detection equipment. [9/11 COMMISSION, 8/26/2004, PP. 97 ] The 9/11 Commission later claims Newark Airport has no video cameras monitoring its security checkpoints, so there is no documentary evidence showing when the hijackers passed through the checkpoint or what alarms may have been triggered. [9/11 COMMISSION, 7/24/2004, PP. 4; 9/11 COMMISSION, 8/26/2004, PP. 35 ] However, Michael Taylor, the president of a security company, who has done consulting work for the New York Port Authority (which operates the airport), claims that Newark does use security cameras at the time of 9/11. [BOSTON HERALD, 9/29/2001] All of the screeners on duty at the checkpoint are subsequently interviewed, and none report anything unusual or suspicious having occurred. [9/11 COMMISSION, 7/24/2004, PP. 4; 9/11 COMMISSION, 8/26/2004, PP. 35 ] The 9/11 Commission later concludes that the passports of Ahmad Alhaznawi and fellow Flight 93 hijacker Ahmed Alnami have suspicious indicators and could have been linked to al-Qaeda, but it does not elaborate on this.

(Shortly Before 8:00 a.m.) September 11, 2001: Two Passengers Allegedly Get Off Flight 93 Just Before Take-off Two passengers leave Flight 93 after hearing an announcement that there will be a five-minute delay in the plane pushing back from the gate. This is according to Terry Tyksinski, a longtime flight attendant with United Airlines, who says a customer service supervisor who witnessed the incident told her about it six months after 9/11. The two first-class passengers are reportedly of dark complexion, “kind of black, not black.” According to Tyksinski, the supervisor notes their names and is subsequently twice interviewed by the FBI. [LONGMAN, 2002, PP. XIII-XIV] No other accounts, including the 9/11 Commission Report, mention this incident. [9/11 COMMISSION, 7/24/2004] And while Flight 93 is delayed on the ground until 8:42 a.m., reports state that it pushes back from the gate just one minute later than its scheduled departure, rather than there being a five-minute delay as Tyksinski suggests. [BOSTON GLOBE, 11/23/2001; MSNBC, 9/11/2006] There will only be 37 passengers on Flight 93, including the four hijackers. This is 20 percent of the plane’s passenger capacity of 182 and, according to the 9/11 Commission, “is considerably below the 52 percent average load factor for Flight 93 for Tuesdays in the three-month period prior to September 11.” [9/11 COMMISSION, 8/26/2004, PP. 36 ] Entity Tags: Terry Tyksinski Timeline Tags: 9/11 Timeline Category Tags: All Day of 9/11 Events, Flight UA 93
