9/11 Conspiracy Theory

EDIT: This video is not mine, but came from Google Video. I embedded it, using their "Put on site" feature.
At first this made me think.. and wonder... Especially the stats about the temperature of the fire not being high enough to melt steel (melting point of steel 1535 degrees C vs. heat of hydrocarbon fire 825 degrees C), and the fact that the building exploded outward so uniformly as it came down (almost as if it was demolished), but then I went and verified their facts.
While it is true that the melting point of iron is close to 1500 degrees C (actually 1510), steel is an alloy and can have a melting point much lower, like 1370 degrees C.
The fire could have gotten hot enough according to this research the temperature of an enclosed hydrocarbon fire can reach 1350 degrees C (look at the RWS curve... almost there... so maybe). Also, the explosions we saw outward could be caused by the water in concrete heating and causing the concrete to explode.
However, the video does raise an important point. We cannot allow our leaders to be given the opportunity to take any of our personal liberties away, just because we feel unsafe. Especially if they are the people telling us we are unsafe.

Remember:

They who would give up an essential liberty for temporary security, deserve neither liberty or security.Benjamin Franklin

P.S. Notice the powerfully moving use of contemporary music throughout this particular piece... interesting choice... perhaps they also had a bit of an agenda here, and it seems their audience is our generation...
