“A central element of the NORAD cover story was that air force jet fighters had heroically chased United 93 [on September 11, 2001]. Had it not crashed in Pennsylvania because of the struggle between the hijackers and passengers, the United plane would have been blown out of the sky before it reached its target in Washington, NORAD had wanted the public to believe. But the tapes [of conversations in NORAD] made it clear that every element of the story was wrong. NORAD knew nothing about United 93 until after it had already plunged to the ground. The tapes showed that NORAD was not notified until 10:07 a.m. that United 93 had been hijacked; the plane crashed at 10:03.”
