that was a question I asked someone. Note the question mark on the end. I was refuting his assertion that the squibs were air.
source??? anyone?
the puffs of smoke accelerated as air rushed out of the WTC! fact, not an explosion of RDX, an explosion of air rushing out gaining speed, not like an explosion slowing down as it expands, but air rushing out and more pressure as it increase and speeds up the air flow, not slowing, accelerating
air
you should be familar with air
