I thought it might be a good idea to give this topic its own thread since people seem interested in exploring it. There is certainly enough evidence available to conclude that there is a mystery. When I first went on about this subject, before The Great Forum Crash, I argued that the buildings collapsed in a manner inconsistent with fire damage or pretty much anything we know of for that matter. On the Sandy Hook thread a video was posted: In it, the first thing Dr. Niels Harrit argues is that we have a great deal of evidence that steel framed buildings do not collapse due to fire. Dr. Judy Wood argues that an unknown technology was responsible for the collapse of the towers: I recently saw one on Netflix, although I can't remember the name of it, that argued that evidence showed that aircraft bore a resemblance to military versions of the commercial aircraft. So there is a lot to debate.
