A while ago I watched a documentary film „Loose Change” proving that WTC collapse was not caused by the planes alone. Although some part’s of the film are just curious, there are few things that did convince me, eg. that WTC collapse took the same amount of time that free falling object would need to fall form the same height, or that no other building collapsed because of fire even thou they where burning up to 20 hours.
