None of which changes the fact the building was designed to withstand only three hours of uncontrolled fire

that is a fuckingly stupid lie that neither you nor agent fairbrother can provide a source for.
You are lying about sources, as you lied about the fall of building seven. You lie about what everyone can see happened in 9/11 The political function of your lies is to provide cover for a government program of importing male military age Muslim rapeugees from subsaharan Africa, and dumping them on marginal Republican federal electorates in flyover country, while turning a blind eye to their rapes and to the fact that nearly all of them are living on crime and welfare. Here, yet again, is the source for the fact that the steel columns holding up World Trade Center Building Seven were only rated for three hours of uncontrolled fire. (Which is longer than would ever happen under normal circumstances, because normally fires in tall buildings are controlled pretty quickly) https://ws680.nist.gov/publication/get_pdf.cfm?pub_id=861610 "For this construction category, columns were required to have a 2 h rating as established by the Standard Fire Test (ASTM E 119); beams were required to have a 1½ h rating. The instructions to the bidders for the WTC 7 job were to bid on a 3 h rating for the columns and a 2 h rating for the metal deck and floor support steel, which corresponded to the more stringent fire resistance requirements for Type 1B (unsprinklered) construction." World Trade Center Building Seven fell after seven hours of uncontrolled fire, which is roughly what one would expect, and it fell largely sideways, not on its own footprint, which is roughly what one would expect in collapse by fire, and it fell piece by piece, not all at the same time, with the outer shell collapsing after everything else, after the innards were gutted by internal collapses, which is roughly what one would expect in a building where the inner floors had a lower fire rating than the columns. And when the outer shell finally collapsed, it started its fall by tilting sideways to the south like a tree notched by a woodman, which is what one would expect in a building that suffered massive damage on the south side, though the primary cause of the collapse was the fire, not the notch on the south side.
