Reply #8: NIST report [View All]

[JackRiddler]

hypothesizes extensive damage to the fireproofing, exposing steel directly to the fire, however with no proof that this actually happened in the way of physical evidence. Because such stripping of the fireproofing would have been a necessity for the collapse model adopted by NIST (as suggested by the UL real-world test of a floor brace in an oven), this assumption is thrown in. It's central to the model, but it's also a circular argument.

NIST testing of real physical evidence cannot show any available core metal was subject to temperatures above 250 C.

NIST advisor, the fire engineer Glenn Corbett, who dismisses any idea of explosives, nevertheless states unequivocally that there is no way to know what kind of damage was done by the plane impacts/explosions to the core columns or the fireproofing. Only the perimeter columns can be seen, otherwise it's all speculative.

He has been very critical of the rapid disposal of the WTC debris. At the time of its disposal, he was among those calling for finding a good spot on the Jersey shore to lay it all out and reconstruct the collapse dynamics using the actual evidence.
