Thank you to the Study = posting this. I don't doubt the events of that day, I don't see any reason to, and no I am not interested in all the youtube videos stating it was all a hoax. I love the argument that this couldn't happened because the buildings wouldn't have collasped because two planes flew into them. Really, what proof do we have of this, have we tested it. Sorry, just have to ask, I know some want to say buildings are constructed a certain way but lets remember how old the World Trade Center was, some construction to have made it more sturdy might not have existed when the towers were built. Also, there was very little brick and mortor on the outside of that building most glass and still, and I have seen a documentary on PBS years ago shortly after the devestating day that showed how the towers did collapse under the heat and strain of what had just happen. It had to do with a bracing system that was used within the towers that started to give, when the last one went so did the towers. To be honest I was stun to know how unstable the towers really were because there wasn't much of a bracing system within, perhaps this is why so many have a hard time swallowing what happened here. But there was a legitimate reasonable explanation, and if it were researched we would discover this.
