Adding: the buildings were built to withstand exactly what happened. Everyone always forgets the rules of physics. There is an equal and opposite reaction that would have to occur from the floors beneath the damage. Simply put, IF something was going to fall or collapse, the lower 80 floors would resist AT SOME POINT. There was no resistance. Only vaporization of steel and everything else within those buildings.
It reminds me of this pic. That shitty building, built nowhere near the standards of the WTC, never collapsed.
