There are a myriad of secrets held in the military, research facilities, and government that no one knows about except those in "need to know" positions.
Obviously you have never worked for the feds or been in the military or you would know that secrets CAN be kept.

Claim: There is no way that jet fuel can burn hot enough to melt the steel in the World Trade Centers. Therefore, the fires from the planes could not be the cause of the Tower's collapse.
Reality: Jet fuel burns at 800 degrees to 1,500 degrees Fahrenheit. Steel melts at somewhere in the ballpark of 2,750 degrees. However, the steel did not have to melt like candle wax to cause a collapse. According to the American Institute of Steel Construction, steel loses 50% of it's strength at about 1,000 degrees. In addition, the jet fuel was not the only substance burning. In extreme heat, steel can expand, then sag, then crack, then give way.

According to the laws of physics, you would have seen the top part of the tower impact something (the rest of the tower), and then falling off over to the side as it was at an angle.
Also, what happened to it? It just pulverized into dust... how does this happen WITHOUT explosives?
Since your article claims that the official story is 100% correct, and I have shown at least two things that are blatant obstructions of physical laws if the official story is correct, then the article is false.

To me the probably most fascinating physical anomaly of the twin towers' collapse was the steel beam that was bent into a U shape without any stress fractures. (This was covered in the film 9/11 MYSTERIES). It plainly takes an incredible amount of heat/force to accomplish that. That in tandem with the ground being too hot, melting rubber boots, for 8 weeks or more is easily indicative of bigger "guns" used than a mere kerosene fire.

I'd like to hear of a structural engineer or whatever other expert physicist who can state that, under anything resembling normal conditions, that a very heavy steel beam can be bent into a U shape without any cracks or breaks (stress fractures). Someone please let me know of whomever can make such a claim.
