This is a scalable context timeline. It contains events related to the event (7:00 a.m.-7:45 a.m.) September 11, 2001: Computer Screening Program Selects Some 9/11 Hijackers; Fails to Stop Them. You can narrow or broaden the context of this timeline by adjusting the zoom level. The lower the scale, the more relevant the items on average will be, while the higher the scale, the less relevant the items, on average, will be.

During this period, all five Flight 11 hijackers check in at Boston’s Logan Airport and board their plane, bound for Los Angeles. The FAA has a program in place called the Computer Assisted Passenger Prescreening System (CAPPS), which is designed to identify those passengers most likely requiring additional scrutiny by airport security (see (6:20 a.m.-7:48 a.m.) September 11, 2001). Ticket records will show that CAPPS selects three of the Flight 11 hijackers at Logan: Since Waleed Alshehri checks no bags his selection has no consequences; Wail Alshehri and Satam Al Suqami have their bags scanned for explosives, but are not stopped. All five hijackers would need to pass through a security checkpoint to reach the departure gate for their flight. Each would have been screened as they walked through a metal detector calibrated to detect items with at least the metal content of a small-caliber handgun. If they’d set this off, they would have been screened with a handheld metal detector. An X-ray machine would have screened their carry-on luggage. However, Logan Airport has no video surveillance of its security checkpoints (see 1991-2000), so there is no documentary evidence of exactly when they pass through them, or if alarms are triggered. According to the 9/11 Commission, none of the checkpoint supervisors later recall seeing any of the Flights 11 hijackers, or report anything suspicious having occurred. [9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 1-2; 9/11 Commission, 8/26/2004, pp. 5-6] However, a WorldNetDaily article will claim that some Logan staff members recall seeing Mohamed Atta (see (6:50 a.m.-7:40 a.m.) September 11, 2001). [WorldNetDaily, 9/21/2001] The Boston Globe will later comment, “aviation specialists have said it is unlikely that more rigorous attention to existing rules would have thwarted the 10 hijackers who boarded two jets at Logan on Sept. 11. At the time, the knives and box-cutters they were carrying were permitted.” [Boston Globe, 10/17/2001]

Sometime during this period, the 9/11 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 Ahmed 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.

When journalists Joe and Susan Trento obtain a copy of the US international no-fly list, which the Transportation Security Administration uses to prevent known terrorists from flying to the US and other countries, they find that 14 of the alleged 9/11 hijackers are still on it. They are: Satam Al Suqami, Waleed Alshehri, Wail Alshehri, Abdulaziz Alomari, Hamza Alghamdi, Fayez Ahmed Banihammad, Ahmed Alghamdi, Mohand Alshehri, Majed Moqed, Hani Hanjour, Salem Alhazmi, Saeed Alghamdi, Ahmed Alnami, and Ahmed Alhaznawi. Shortly after 9/11, it was reported that some of the hijackers were still alive (see September 16-23, 2001) and this may be the reason for the apparent error, although the set of hijackers reported to be still alive and the set of 14 hijackers still on the no-fly list only partially overlap. [Trento and Trento, 2006, pp. 189-192] The no-fly list also contains manifold problems and at least one other dead terrorist is on it (see March 2006).
