The collapse was inevitable

“The fireball that shot from the second WTC tower hit, opposite where the jetliner penetrated, blew out windows and perhaps part of the latticework exterior structure. Flaming fuel probably cascaded down the shafts of elevators and ductwork and stairwells whose fire-protection enclosures would have been destroyed by the explosive crash and ballistic heavy plane parts. These fuel flames, and fires started from them, would have weakened interior structural support beyond protection provided by code-required fireproofing. Once the interior structural supports were weakened, and the exterior lattice lost its integrity collapse was inevitable.”
