“In Part 1 of this series, I examined what is perhaps the most consequential and flagrantly false aspect of the computer modeling performed by NIST during its six-year investigation into the destruction of World Trade Center Building 7. This was NIST’s omission of an important structural component called ‘web stiffeners’ that were attached to a girder on the 13th floor of Building 7. . . .

“In Part 2, I will examine the three other aspects of NIST’s probable collapse sequence that were critiqued in the first half of the request for correction. . . .

“Whereas NIST provided a totally ludicrous explanation for having the omitted web stiffeners from its model, it essentially provided no response whatsoever regarding these other three items in the request for correction. This was despite the fact that these sections of the request for correction invited NIST to stand by the claims in its report if it could substantiate them with further information. Instead, NIST declined to provide even the most basic of information to substantiate these aspects of its probable collapse sequence.”
