Not very convincing...These buildings came down in 11 seconds....The floors below the so called infernos were all regular temperatures and wouldn't' collapse by pancaking.. They would have bent under pressure....Count the floors they say supposedly collapsed by saying Onethousand one, Onethousand two...It takes 10 times that 11 seconds they claimed for this free fall...
Another bit of nonsense, the Middle columns consisted of 46 HUGE structural steel columns and ALL of them would ha had to been severed, ALL of them, one supposed "plane" and I use that term loosely, was way off to the side and obviously would have only caught a few columns and the further floor plan side opposite to where the action took place would have been normal temperatures because it was not damaged at all. . ALL those huge core columns would have had to be severed, see the 27:52 mark
This video is NONSENSE...Metal beams get soft but don't snap or break like bones, they just sag, these answers they give for this collapse violate the Laws of Thermodynamics in heat transfer...
