Hani Hanjour, one of the men who will allegedly hijack Flight 77, passes through a security screening checkpoint at Washington’s Dulles International Airport without incident. 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. [Federal Bureau of Investigation, 9/19/2001] Two of the other Flight 77 hijackers passed through the west checkpoint 17 minutes ago (see 7:18 a.m. September 11, 2001) and two more will go through it a minute later (see 7:36 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 3; 9/11 Commission, 8/26/2004, pp. 27] The FAA’s Washington Civil Aviation Security Field Office will investigate the security screening at Dulles Airport today, and the screeners who were on duty will report having encountered no suspicious activity and nothing out of the ordinary this morning.
