As we watched the black plume gather strength, less than a minute after the explosion, we saw an odd sight that no one else has yet commented on. Directly in back of the plume, which would place it almost due west from our office, a four-engine propeller plane, which Ray later said resembled a C-130, started a steep decent towards the Pentagon. It was coming from an odd direction (planes don't go east-west in the area), and it was descending at a much steeper angle than most aircraft. Trailing a thin, diffuse black trail from its engines, the plane reached the Pentagon at a low altitude and made a sharp left turn, passing just north of the plume, and headed straight for the White House.
