@xxdesertstorm Those other buildings didn't collapse because they had a different type of construction. The WTC was a tube with floors and minimal columns on the inside. Typically buildings would have more internal supports, and the floor beams may even be attached differently. The airplanes broke the stability of the shell, and there was aviation fuel spilled all through the impact zone causing high temperature fires.
