[Federal Bureau of Investigation, 9/19/2001; 9/11 Commission, 4/6/2004 pdf file] A surveillance camera located above the British Airways ticket counter points toward the American Airlines ticket counter, and therefore records alleged hijackers Nawaf Alhazmi and Salem Alhazmi when they check in at the airport (see 7:29 a.m. September 11, 2001). [Federal Bureau of Investigation, 9/25/2001] Another surveillance camera located by the British Airways ticket counter also points toward the American Airlines ticket counter, and records alleged hijackers Khalid Almihdhar and Majed Moqed when they check in (see 7:15 a.m. September 11, 2001). [Federal Bureau of Investigation, 9/19/2001; Federal Bureau of Investigation, 9/19/2001] All five of the alleged hijackers of Flight 77 are recorded on video as they go through a security checkpoint at the airport (see 7:18 a.m. September 11, 2001, (Shortly Before 7:35 a.m.) September 11, 2001, and 7:36 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 3; 9/11 Commission, 8/26/2004, pp. 27] Dulles Airport is the only one of the three airports used by the hijackers this morning that has videotaping equipment in use at its security checkpoints. Consequently, William Johnstone, a member of the 9/11 Commission staff, will later note, “the most specific information that exists about the processing of the 9/11 hijackers is information about American Airlines Flight 77,” which will take off from Dulles Airport this morning (see (8:20 a.m.) September 11, 2001). [9/11 Commission, 1/27/2004] In 2004, news organizations will receive a copy of a surveillance video apparently showing the alleged hijackers passing through a security checkpoint at Dulles Airport before boarding Flight 77. The Associated Press will describe the video as “grainy” and report that details are “difficult to distinguish.” It will note that “[n]o knives or other sharp objects are visible” on the video.

[Source: FBI]Khalid Almihdhar and Majed Moqed, two of the men who will allegedly hijack Flight 77, go through a security screening checkpoint at Washington’s Dulles International Airport. They are screened at the west checkpoint in the airport’s main terminal. Screening passengers is the responsibility of United Airlines, but it contracts the work to Argenbright Security.
Hijackers Set Off the Metal Detector Alarms - After entering the checkpoint, Almihdhar and Moqed place their carry-on bags on the X-ray machine belt and then pass through the first walk-through metal detector. Both men set off the alarm. They are therefore directed to go through a second metal detector. Almihdhar passes through this without any problems but Moqed again sets off the alarm. This leads to him being screened by a security officer with a handheld metal detector wand. No problems are found and so he is allowed to proceed on his way. None of the men’s carry-on bags are inspected by checkpoint personnel. As Moqed is leaving the checkpoint area, he appears to intentionally look down at the floor as he passes a security camera, thereby preventing the camera from capturing a close-up of his face. The other three Flight 77 hijackers will go through the west checkpoint 17 or 18 minutes later (see (Shortly Before 7:35 a.m.) September 11, 2001 and 7:36 a.m. September 11, 2001). [Federal Bureau of Investigation, 9/19/2001; 9/11 Commission, 7/24/2004, pp. 3; 9/11 Commission, 8/26/2004, pp. 27]
Screeners Will Recall No Suspicious Activity - Immediately after today’s terrorist attacks, the FAA’s Washington Civil Aviation Security Field Office will investigate the security screening at Dulles Airport. It will interview 43 of the 44 screeners who were on duty today, and these employees will all report having encountered no suspicious activity and nothing out of the ordinary this morning. [9/11 Commission, 7/24/2004, pp. 3; 9/11 Commission, 8/26/2004, pp. 93] However, lawyer Ron Motley, whose firm will represent some families of victims of today’s attacks, will later criticize the screeners at Dulles Airport, commenting, “Even after setting off these alarms, the airlines and security screeners failed to examine the hijackers’ baggage, as required by federal regulations and industry-mandated standards, or discover the weapons [the hijackers] would use in their attack.” [Associated Press, 7/22/2004]

Vaughn Allex.Vaughn Allex. [Source: USA Today]Brothers Nawaf Alhazmi and Salem Alhazmi, two of the men who will allegedly hijack Flight 77, check in at the American Airlines ticket counter at Washington’s Dulles International Airport. [9/11 Commission, 7/24/2004, pp. 3, 452; 9/11 Commission, 8/26/2004, pp. 27] They are running late. They “come running in the front door, looking around, and didn’t know which way to go,” Vaughn Allex, an employee at the ticket counter, will later describe. [CNN, 9/8/2012; ABC 7, 9/10/2016] They are captured on security video pulling large, dark, roller-type suitcases as they approach the counter. [Federal Bureau of Investigation, 9/19/2001] They are allowed to check in despite having missed the official deadline for doing so by a few minutes. [CNN, 9/8/2012; ABC 7, 9/10/2016]
Trainee Checks in the Hijackers - Nawaf and Salem Alhazmi are checked in by Inga Hill, a trainee who is overseen by Allex. [Federal Bureau of Investigation, 9/19/2001; Federal Bureau of Investigation, 9/25/2001] Today is only her second day working at Dulles Airport. [Federal Bureau of Investigation, 9/12/2001] Allex looks on while she confirms the brothers’ tickets. [Federal Bureau of Investigation, 9/25/2001] The Alhazmis check in two dark-colored bags, one of them a hard plastic suitcase, the other a soft bag, Hill will recall. One of the brothers has a carry-on bag, she will say. [Federal Bureau of Investigation, 9/12/2001] Allex will recall the brothers having only one bag, which he considers to be “totally inappropriate for a trip to Los Angeles.” The bag is “almost like a satchel” with straps across the top but which doesn’t seal, he will say. [CNN, 9/8/2012]
Hijackers Have Difficulty Answering Questions - Nawaf and Salem Alhazmi show passports for their photo identification but are unable to recall the country from which these were issued. They also have trouble answering the security questions that all passengers must answer. Allex therefore has to get involved and take over the task of questioning them, Hill will recall. [Federal Bureau of Investigation, 9/12/2001] However, Allex will say he takes on the task of checking them in from the outset because they are running late. [CNN, 9/8/2012] Nawaf Alhazmi is the only one of the brothers who speaks during the check-in, but his English is poor. Salem Alhazmi, meanwhile, acts “very anxious or excited,” according to Allex. [Federal Bureau of Investigation, 9/12/2001; Federal Bureau of Investigation, 9/25/2001] “He was grinning, he was smiling, and he was dancing back and forth,” Allex will say. [CNN, 9/8/2012]
Hijackers Are Selected for Extra Scrutiny - Allex selects the two brothers for extra security scrutiny. He does this because he finds them suspicious, and one of them—probably Salem Alhazmi, according to the 9/11 Commission—has no photo identification and cannot understand English. However, the only consequence of the extra scrutiny will be that their bags are held off Flight 77 until it is confirmed that they have boarded it.
Employee Is Suspicious and Follows the Hijackers - After being checked in, Nawaf and Salem Alhazmi proceed to a security screening checkpoint (see 7:36 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 3; 9/11 Commission, 8/26/2004, pp. 27-28; USA Today, 9/12/2016] They no longer have their suitcases with them when they leave the ticket counter. [Federal Bureau of Investigation, 9/19/2001] Allex is still uncomfortable with the two men and follows them for a few steps. He stops himself, though, as he is concerned that his suspicion may be racially motivated. [CNN, 9/8/2012] The name of Nawaf Alhazmi was recently added to a terrorism watch list (see August 23, 2001). [Associated Press, 7/22/2004; 9/11 Commission, 7/24/2004, pp. 270] An employee at Dulles Airport will recall encountering him and four other Middle Eastern men as they tried to get to a secure area of the airport the previous evening (see (Between 8:00 p.m. and 8:45 p.m.) September 10, 2001).

He is screened at the west checkpoint in the airport’s main terminal. [9/11 Commission, 7/24/2004, pp. 3; 9/11 Commission, 8/26/2004, pp. 27] He has two carry-on bags with him: a small black suitcase and a black bag with a shoulder strap. [Federal Bureau of Investigation, 9/19/2001] After entering the checkpoint, he places them on the X-ray belt and walks through the metal detector. He sets off no alarms and so, after picking up his bags, proceeds on his way. [9/11 Commission, 7/24/2004, pp. 3; 9/11 Commission, 8/26/2004, pp. 27] His carry-on bags are not physically inspected at the checkpoint.

[Source: FBI]Brothers Nawaf Alhazmi and Salem Alhazmi, two of the men who will allegedly hijack Flight 77, go through a security screening checkpoint at Washington’s Dulles International Airport. They are screened at the west checkpoint in the airport’s main terminal. Both men have one carry-on bag. After entering the checkpoint, Salem Alhazmi walks through a metal detector without setting off the alarm and so is allowed to continue on his way. However, Nawaf Alhazmi sets off the alarm when he passes through it and so he has to walk through a second metal detector. He again sets off the alarm. He is therefore hand-wanded by a member of staff and has his carry-on bag swiped by an explosive trace detector. These checks apparently find no problems and so he is allowed to proceed on his way. Salem Alhazmi’s bag is not physically inspected while the two men are at the checkpoint, nor are the contents of Nawaf Alhazmi’s bag. Security camera footage will later reveal that Nawaf Alhazmi has an unidentified item clipped to the rim of the back pocket of his pants. One of the other Flight 77 hijackers passed through the west checkpoint a minute ago (see 7:35 a.m. September 11, 2001) and two more passed through it 17 minutes before that (see 7:18 a.m. September 11, 2001).

Susan Trento.Susan Trento. [Source: DC Bureau]FBI agents are able to identify the alleged hijackers of Flight 77 surprisingly quickly on video recorded this morning by security cameras at Washington’s Dulles International Airport, from where Flight 77 took off. [Trento and Trento, 2006, pp. 36-37; Priska Neely, 10/21/2010] FBI agents arrived at Dulles Airport at around 12:40 p.m. (see (12:40 p.m.) September 11, 2001). [9/11 Commission, 9/29/2003 pdf file] The first thing they did there was seize the security video of the west checkpoint in the airport’s main terminal. [Trento and Trento, 2006, pp. 36] The five alleged hijackers passed through this checkpoint on their way to boarding Flight 77 (see 7:18 a.m. September 11, 2001, 7:35 a.m. September 11, 2001, and 7:36 a.m. September 11, 2001) and were captured on video as they did so (see 7:15 a.m.-7:36 a.m. September 11, 2001). [Federal Bureau of Investigation, 9/19/2001; 9/11 Commission, 7/24/2004, pp. 3]
FBI 'Knew Who the Hijackers Were' - FBI agents now bring Ed Nelson, the supervisor in charge of the west checkpoint, the video recorded at the checkpoint this morning for him to examine. As he watches it with them, he is surprised that they already seem to know who the Flight 77 hijackers were and what they looked like. The agents “went right to the first hijacker on the tape and identified him,” Nelson will later recall. “They would go ‘roll’ and ‘stop it,’ and showed me each of the hijackers,” he will say. He will remark that both of the metal detectors at the checkpoint were open around the time the hijackers were screened and “lots of traffic was moving through.” In light of this, he will say, “picking people out [on a video recording] is hard.” And yet the agents “knew who the hijackers were out of hundreds of people going through the checkpoints.” When an interviewer asks him, “How would they know?” since the “FBI claimed they had no idea who these hijackers were,” Nelson will reply: “Oh, exactly. Yeah, it boggles my mind.” He will comment: “I wanted to know how they had that kind of information. So fast. It didn’t make sense to me.” [Trento and Trento, 2006, pp. 36-37; Priska Neely, 10/21/2010]
FBI Knew Who the Hijackers Were 'the Day Before,' Journalist Will Suggest - US Customs reportedly provided the FBI with the passenger lists and the names of the probable hijackers for the four hijacked flights within 45 minutes of the terrorist attacks this morning (see (11:00 a.m.) September 11, 2001). [9/11 Commission, 1/26/2004] Whether this helped the FBI agents at Dulles Airport to identify the hijackers on the security video is unclear. Investigative journalist Susan Trento will comment on their ability to recognize the hijackers so quickly, stating, “What it says to me is… if they knew [the hijackers] that morning, they knew who they were the day before and they should have been able to catch them before they got to the airport.” [Priska Neely, 10/21/2010]

Majed Moqed’s identification card found in the rubble.Majed Moqed’s identification card found in the rubble. [Source: FBI]Two or three documents belonging to the Flight 77 hijackers are found in the rubble at the Pentagon. One is a “Kingdom of Saudi Arabia Student Identity Card” with Majed Moqed’s name on it. Forensic examination will later indicate that the card may have been fraudulent. [9/11 Commission, 8/21/2004, pp. 44 pdf file] Another is Nawaf Alhazmi’s USA ID card. [9/11 Commission, 8/21/2004, pp. 27, 42 pdf file; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] The 9/11 Commission will say that Salem Alhazmi’s USA ID is also found, although this will not be mentioned at the trial of Zacarias Moussaoui, where an otherwise exhaustive list of the hijackers’ ID found at the crash sites is submitted. [9/11 Commission, 8/21/2004, pp. 27, 42 pdf file; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] In addition, the Commission will say that Salem Alhazmi was unable to produce a photo ID when checking in for his flight on 9/11 (see 7:36 a.m. September 11, 2001), so it is unclear how the document could have come to be at the Pentagon. Based on report from the Secret Service, the 9/11 Commission will say these two documents appear genuine. However, they may actually be fakes (see (July-August 2001)). [9/11 Commission, 8/21/2004, pp. 27 pdf file] There are at least a couple of other reported instances of other similar paper-based objects surviving the same plane crash, as well as that of Flight 93 in Pennsylvania (see After 10:06 a.m. September 11, 2001).

The 9/11 Commission attempts to make a list of all identity documents obtained by the hijackers, but its account, contained mostly in its Terrorist Travel Monograph, may be incomplete:
bullet The Commission says several of the hijackers obtained USA ID cards in the summer of 2001 (see (July-August 2001)), although at least one, and possibly more of the cards is fake, and this is not mentioned by the Commission. According to it, Khalid Almihdhar, Nawaf Alhazmi, and Abdulaziz Alomari obtained their cards on July 10. However, the Commission gives conflicting dates for Salem Alhazmi, Majed Moqed, and Ahmed Alghamdi. For example, in one place it says Alghamdi got his card in July and in another it says he got it in August. At least one card, that of Khalid Almihdhar, is fake and ID forger Mohamed el-Atriss will be arrested after 9/11 and sentenced to jail for forging IDs for the hijackers (see (July-August 2001) and November 2002-June 2003). The Commission further says that the Alhazmi brothers’ cards were “found in the rubble at the Pentagon,” citing a US Secret Service report. Although an image of a damaged USA ID card belonging to Nawaf Alhazmi will be produced as evidence at the trial of Zacarias Moussaoui, according to the 9/11 Commission Salem Alhazmi was unable to produce any photo ID when checking in for his flight on 9/11 (see 7:36 a.m. September 11, 2001), so it is unclear how his card came to be at the Pentagon. In addition, in the Commission’s Terrorist Travel Monograph, the mention of Salem Alhazmi’s card in the list of hijackers’ ID will be followed by a reference to an endnote. However, this endnote is missing; [9/11 Commission, 8/21/2004, pp. 27-29, 31-32, 34-44 pdf file; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006]
bullet FBI Director Robert Mueller will later say that the six hijackers who obtained USA ID cards plus Mohamed Atta obtained unspecified identification cards in Paterson, New Jersey (see July 2001). However, it is unclear whether this statement refers to the USA ID cards, or a different set of ID cards not mentioned by the 9/11 Commission;
bullet The Commission will say that Satam Al Suqami did not obtain any ID document in the US, which is why he had to take his passport on his final flight. The passport was found shortly after the plane he was traveling on hit the WTC (see After 8:46 a.m. September 11, 2001). [9/11 Commission, 8/21/2004, pp. 27-29, 31-32, 34-44 pdf file] However, Florida media reported a man named Satam Al Suqami obtained a Florida ID card on July 3, 2001, around the same time as several other hijackers obtained similar cards; [St. Petersburg Times, 9/16/2001]
bullet Ahmed Alhaznawi had a Florida’s driver’s license and two duplicates. Although the Commission mentions the original license and second duplicate, it does not mention the first one, issued on July 24, 2004.
