NOT Cutter Charges in the North Tower

[William Seger]

10. My analysis doesn't prove it isn't an orc smoking a cigar, either

... but it DOES prove that this video IS NOT EVIDENCE of a controlled demolition, since no aspect of the puff resembles a "squib": In the first frames, it is moving at a fairly constant speed, completely unlike the "squib" in the first video, and the rush of air that later accelerates it carries identical-looking smoke. If you prefer to believe that there was a demolition charge involved somehow, inexplicably set off after the building was already falling, despite having no credible evidence for it, knock yourself out. Just don't offer this video as evidence.
