Fireball

Photo Showing Burning Tree Right of Pentagon Crash Center

This reproduction of a photograph by Daryl Donley shows a large fireball centered about fifteen feet to the right of the middle of the damaged part of the Pentagon's facade.
The photograph does not capture the moment of impact, since there is dark smoke rising from the ground far to either side of the fireball.
The fireball appears to be the result of the combustion of a small tree in front of the facade.
