In reply to the discussion: Cutter Charges in the North Tower... [View all]cherokeeprogressive
(24,853 posts)64. Riddle me this, billman...
The little jet of smoke discussed at 0:48 and beyond is moving at exactly the same speed as the smoke/debris surrounding it.
If this jet of smoke were the result of some kind of explosion, wouldn't, SHOULDN'T it be moving at oh, 1800 m/s to 8000 m/s, which is the rate of expansion of most commercial explosives?
Don't you find that a little strange that the jet of smoke caused by an explosion moves only as fast as that of the smoke/debris we KNOW is forced out of the building by the bellows effect of pancaking floors?
I do, don't you?
