You're talking about 2 planes, flying at hundreds of miles an hour, filled with jet fuel, with enormous amounts of mass, colliding with fixed steel structures. Imagine 200 tons of steel and jet fuel crashing into structures. If you take a Hummer and a Volkswagen and have one travel at 50mph and the other at 100mph and crash them into stop sign the outcome is the same, the sign is done for.

This is a pointless debate. Conspiracy theorists are going to cite regurgitated information from conspiracy theory websites, non-conspiracy theorists are going to cite sources from government and popular mechanics magazines. Each side will discredit the other side's sources.

We've got sources like the Northwoods Documents, which was a plan that was never carried out. There are thousands of documents in our government that play out different scenarios, most of which will never be used. We've got the popular mechanics article, which I think does an excellent job at debunking the myths. But what it really comes down to is your beliefs. There are a lot of impressionable people on both side of the debate that believe what others tell them.

Its my opinion was that it was carried out by terrorists. The buildings collapsed because planes crashed into them. That is a lot easier to believe than the government can keep a secret, especially one so big that would have to involve hundreds of people to carry out. I say no, even if they wanted to our government is to incompetent to pull that feat off.
