I’m attempting to construct a timeline.

This morning at least four commercial airline flights were hijacked, though it remains unclear at what point in their itinerary their paths were diverted. The flights were American Airlines #11 (Boston to LA) and #77 (Dulles to LA) as well as United Airlines #93 (Newark to SF) and #175 (Douglas in VA to LA). The contact numbers for the airlines are 1-800-245-0999 and 1-800-932-8555, respectively. Flight #11 was on it’s regular flight path until it took a sharp turn in upstate New York. A flight path indicator shows that it made a beeline for New York City. Despite initial reports that may have been to the contrary, three of the planes were Boeing 757 and 767’s.

At 8:42 AM there was an explosion that was the result of a plane colliding with one of the World Trade Center Towers. Immediately people were told to evacuate, but in the unaffected building the evacuation order was rescinded and people returned to their offices. Under a half hour later (roughly 18 minutes) a second passenger airplane appeared on the skyline and collided with the second largely unevacuated tower. This was broadcast nationally on live network television.

Shortly thereafter (before 10:15am) a third airplane slammed into the Pentagon, entering in it’s E-ring, and penetrating into the 4th and 5th corridors of the C & D rings. Debris spread as far as the E ring. No specific office in the Pentagon appears to have been targeted. There have been scattered reports of a car bomb at the State Building and an attack on Camp David, but to this point they remain unconfirmed. However, a plane carrying 38 passengers, 2 pilots, and 5 flight attendants crashed in midstate Pennsylvania outside of Pittsburgh. My local Fox affiliate reported that someone inside the plane called local county dispatchers and claimed that they had been hijacked shortly before the crash. There is still little speculation on where this flight had been headed or if the unplanned grounded was a result of a herioc act by the crew. There are no reported survivors.

All told the plain crashes themselves involved over 260 casualties.
