64. NIST's discounting of charges was based on the use of RDX,

a WWII-era explosive. Why?

Use of explosive charges inside the hollow core columns sized to bulge out, but not break, incendiary-preheated column walls
would not make any noise at all, because the noise would be contained inside the column and absorbed in the work of bulging the column walls. Bulged columns would then buckle and fail.

The outcome may be plausible to you, but that is because you have never bothered to familiarize yourself with the issues and because you have believed lying liars who lie to you about a building belching smoke from every window.

The "kink" only exhibited itself as the building started the collapse. You are probably referring to what Chief Hayden called a "bulge". I'm not aware that Chief Hayden's account of a bulge around the 13th floor on the SW corner has ever been corroborated by anyone, and it is contradicted by the NYPD helicopter photo that seems to show that at the 13th floor there was no SW corner.

The NIST report on WTC7 indicates that some people went into the basement at about 3:00 pm to rescue some security dogs from the kennels there, and they found such severe damage in the basement that they abandoned their mission. I'm not aware that NIST ever addressed the question of the engine shaft. Of course, if we'd had a proper scientific deconstruction of the pile, we would know exactly where it was if it was stopped by WTC7.
