WTC Building 7 collapse explained. Everyone knew it was going to collapse from fires. | NateTalksToYou

From a physical standpoint, the collapses of the Twin Towers and especially WTC 7 show features far more consistent with controlled demolition than fire or plane damage. Both towers fell at near free-fall acceleration for portions of their descent, meaning the structures below offered virtually no resistance as the upper sections came down. In physics, this would require the simultaneous failure of all support columns—something fire alone, which weakens materials unevenly and gradually, is unlik
