Right, I’ve got to the interesting bit,
Chapter 4.0 SIMULATING THE COLLAPSE OF WTC 7
4.1 Key Features of the Collapse:
– This section omits the initial half second of descent of WTC7’s roofline at uniform velocity, as measured by Chandler.
4.1.1 Discussion of NIST’s Progressive Collapse Simulation:
– “Such differential movements in the exterior would be extremely likely to have caused window breakage, cracking of the façade, and exterior deformation, none of which were observed”
False. Window breakage seems to appear on some videos; Truthers, predictably, claim this to be “squibs”.
