Reply #28: A firefighter at Pentagon said the trailer outside produced most of smoke

[philb]

(A fireflighter implied that aviation fuel wasn't the sole source of the trailer fire but SOMETHING THAT ONLY FOAM WOULD EXTINGUISH..)

Firefighter Russell Dodge said. "There were two vehicles burning, along with a construction trailer - we didn't know at the time, but that trailer was the main producer of smoke on the outside of the building - and the foam truck. "Once I had pretty much knocked down, then I went into the area of the first floor where all the fire was, and just trying to get on that," he said. "It was something to fight with, until we got the other foam trucks there." He said the foam units got there and concentrated on the area of the construction trailer, which was producing some severe fires and subsequent mini explosions due to highly flammable chemicals in it, then on the actual point of impact from the hijacked aircraft.

Is this what caused the loud explosion heard by many?
