The End
While all of this is happening in New York, Flight 77 that departed from Dulles International Airport in Washington D.C. hits the Pentagon at 9:37am. The panic that insued from now three planes in less than an hour hitting three seperate buildings was enough for the FAA at 9:42am to ground all planes, but there was still one more that was not responding.
Then at 9:59am, a rumbling is heard, and smoke starts to pour into the streets, as people look up, they see the South Tower falling.
At 10:03am, Flight 93 that had been unresponsive crashes several miles from Camp David in Somerset County, PA. Then 10:28 am, the North Tower collapses.
