When the third plane hit the Pentagon I was sitting in my car at a traffic light several blocks away. (Corner of Jeff-Davis Hwy and 23rd, for those who know the area.) I had no idea what happened--I thought it was some sort of construction accident, maybe an explosion of natural gas or something. I just saw a giant mushroom cloud of smoke and fire from the crash rise over a building. I thought the explosion was just on the other side of the building, about a block away from me. But it was actually closer to seven or eight blocks away, at the Pentagon. That was a pretty freaky day in Washington D.C.
