Bingham is believed to have been among the passengers who attempted to storm the cockpit to try to prevent the hijackers from using the plane to kill hundreds or thousands of additional victims. He made a brief airphone call to his mother, Alice Hoglan, shortly before the plane went down. Hoglan, a former flight attendant with United Airlines, later left a voice mail message on his cell phone, instructing Bingham to reclaim the aircraft after it became apparent that Flight 93 was to be used in a suicide mission.
