I was just watching the show ‘9/11 : science and conspiracy’ and there are a few questions that i have that maybe this site could address. In the I-beam test, they used a smaller beam! Why? Of course if you use the same fuel and a thinner beam it makes the test false because ALL the materials were not scaled. Of course the heat will penetrate a thinner beam but what about the fact that the beams used in the towers were 3-4 times thicker, was the heat scaled to account for this? What about the composition of the thin beam compared to the thick ‘real’ beam? When they did the rail test to see if an aluminum tube would disintigrate when hitting a ‘mock’ wall, did they not put wings on it to see what sort of indentation they made? Also, when an explosive is travelling, it becomes a shaped charge does it not? On the other hand as well, it make sense that the military would try this to test the strength of the new reinforcement structure they just built into the pentagon.  As for the thermite idea, how do people explain the apparent’ nice’ cut on the real beams if they were demolished by vertical stresses? Another point in the show is how are people kept quiet when dealing with conspiracy. It’s simple, just execute a person in front of the people and tell them that they will recieve the same fate. fear is a powerful motivator and the US government is notorius for tortue and other behavoir modification techniques. Finally, what concerns me the most is the technology that the US government has concealed in the name of security. All they have to do is say that something is in the name of national security and no one will ever find out! One more final point, notice that when the offical report wasn’t accepted seems to be about the same time that bush made it impossible to be tried for crimes that involve so-called national security!?
