9:35 a.m. September 11, 2001: Flight 93 Attendant Warns United Airlines about Hijacking; Information Passed on to United’s Crisis Center

An unknown flight attendant on Flight 93, later determined to be Sandy Bradshaw, calls the United Airlines maintenance facility in San Francisco, and reports that her plane has been hijacked. The San Francisco number is one that flight crews know to call if they need to report mechanical problems, obtain advice on troubleshooting, or request maintenance while in flight. [9/11 Commission, 8/26/2004, pp. 40; United States of America v. Zacarias Moussaoui, a/k/a Shaqil, a/k/a Abu Khalid al Sahrawi, Defendant., 4/11/2006 ] Bradshaw makes her call from the rear of Flight 93, using an Airfone. [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 ] A United Airlines maintenance employee initially answers the call. Shortly thereafter, it is taken over by a manager at the facility. Bradshaw reports that hijackers are in the cabin of her plane behind the first-class curtain, and also in the cockpit. They have pulled a knife, have killed a flight attendant, and have announced they have a bomb on board. The manager will later describe Bradshaw as being “shockingly calm” during the conversation. [9/11 Commission, 8/26/2004, pp. 40; United States of America v. Zacarias Moussaoui, a/k/a Shaqil, a/k/a Abu Khalid al Sahrawi, Defendant., 4/11/2006 ] Bradshaw’s call lasts just under six minutes. [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] The manager reports the emergency to his supervisor, who passes the information to the crisis center at United Airlines’ headquarters, outside Chicago. [USA Today, 8/12/2002; 9/11 Commission, 8/26/2004, pp. 40] After about 9:45-9:50, “everyone” in the crisis center will know “that a flight attendant on board” Flight 93 has “called the mechanics desk to report that one hijacker had a bomb strapped on and another was holding a knife on the crew.” [Wall Street Journal, 10/15/2001; 9/11 Commission, 8/26/2004, pp. 43] The manager at the San Francisco maintenance facility instructs the Airfone operator to try and reestablish contact with the plane, but the effort is unsuccessful. [9/11 Commission, 8/26/2004, pp. 40] At 9:50, Bradshaw will make another call from Flight 93, this time to her husband (see 9:50 a.m. September 11, 2001). [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 12 ]
