The flight was scheduled to depart at 08:10, but ended up departing 10 minutes late from Gate D26 at Dulles. The last normal radio communications from the aircraft to air traffic control occurred at 08:50:51. At 08:54, Flight 77 began to deviate from its normal, assigned flight path and turned south, and then hijackers set the flight's autopilot heading for Washington, D.C. Passenger Barbara Olson called her husband, United States Solicitor General Theodore Olson, and reported that the plane had been hijacked and that the assailants had box cutters and knives. At 09:37, American Airlines Flight 77 crashed into the west facade of the Pentagon, killing all 64 aboard (including the hijackers), along with 125 on the ground in the Pentagon. In the recovery process at the Pentagon, remains of all five Flight 77 hijackers were identified through a process of elimination, as not matching any DNA samples for the victims, and put into custody of the FBI.
