“The earliest written confirmation of President Bush’s shoot-down order for any hijacked plane headed toward the capital came at 10:20 a.m. [on September 11, 2001] when White House press secretary Ari Fleischer, on Air Force One, recorded that the president had issued the directive. That was a full 17 minutes after Flight 93’s demise concluded the morning’s grisly chain of events. The time from the notification of the first hijacking [of Flight 11] to the crash of Flight 93 was 104 minutes.”
