WTC7 seems to be a classic controlled demolition. WTC 1 &2 destruction appears to have been enhanced by thermate (a variation of thermite) in addition.
Pentagon was not struck by a passenger aircraft. It was a drone or missle.
Begin a broken record here (playing over and over): Steel buildings don't collapse due to fire dunderheads! WTC Collapses/disintegrations like 911 happen due to detonated charges = bombs. "tower stayed upright despite fears of collapse"
