We all know the trade centers (including building 7) fell. We also know thousands died. But who really killed them? New York firefighters know there were other factors besides airplanes and fires. Explosives and thermite came up in many conversations. Controlled demolition seemed to be the theory of many. Building experts and architects said the collapse of building 7 defied logic and physics. It also appears to be one of the greatest insurance frauds in history. If the real truth ever comes out it is going to make one hell of a movie.
