Despite the multitude of newspaper and other media accounts, congressional and Commission testimony, and books and periodicals devoted to the government’s response to the 9/11 attacks, the operational sequence that follows has never been told. Indeed, the facts of the morning of 9/11 directly contradict the official version of events, as presented publicly in testimony proffered before this Commission on May 23, 2003. Our chronology reveals the greatest amount of notice the military received of any of the 4 hijacked planes was the 9 minutes’ notice NEADS received of the first hijacked aircraft, American 11, prior to it crashing into the North Tower of the World Trade Center at 8:46:40. NEADS received notice of the second hijacked plane, United 175, as it exploded into the South Tower of the World Trade Center at 9:03:02. NEADS received no notice that American 77 was hijacked (it received a report that the aircraft was missing, with no mention of its having been hijacked or of its location, three-to-five minutes before American 77 crashed into the Pentagon at 9:37:46). Finally, NEADS received notice that United 93 was hijacked at 10:07, four minutes after the flight had crashed in a field in Pennsylvania at 10:03:11.
