Again, all of my points are coming from my recollection of the Loose Change video. As to how much misrepresentation the creator did when he made it I can't say.
I've been skimming through the video again to try to find my cordite reference and I was mistaken. The cordite quotes were actually taken from the pentagon, not the WTC as I originally posted. Between the 26 and 27 minute marks of the video they quote a couple of people that say that they smelled cordite. In addition, they claim that the color of the blast and fire was not the color of a jet fuel fire, but a silvery small fire that matches a cordite fire.
Another point of interest is that there were 3 cameras that would have captured the entire incident at the pentagon. The FBI confiscated all 3 tapes within minutes and has never released them. All they would have to do to prove that it was a plane that hit the pentagon would be to release one of these videos.
It's all food for thought. Remember to always take what you watch in these movies with a significant dose of sceptisism. You never know what motives the creators have.
