Kelli Arena

Based on information from the plane’s flight data recorder, the National Transportation Safety Board will later determine that Flight 93’s autopilot is turned off at “about 10:00,” and remains off for the flight’s final minutes. [National Transportation Safety Board, 2/13/2002 ] Phil Bradshaw, whose wife is an attendant on Flight 93, will later hear the plane’s cockpit voice recording. Being a pilot himself, he recognizes on it the sound of the alarm that goes off when the autopilot is disconnected. [News and Record (Piedmont Triad, NC), 9/11/2002] CNN’s Kelli Arena will hear the recording during the 2006 Zacarias Moussaoui trial and will report that, shortly after this alarm sounds, “Another alarm goes off.” [CNN, 4/12/2006] According to journalist and author Jere Longman, as well as the alarm set off when the autopilot was disconnected, another alarm “would have sounded because the plane was traveling at five hundred seventy-five miles an hour in the final minutes, far exceeding the design limits of four hundred twenty-five miles an hour below twenty thousand feet and two hundred eighty-seven miles an hour below ten thousand feet.” [Longman, 2002, pp. 208] So presumably this is the second alarm described by Arena.
