Dude this guy ripped off the pentagon conspiracy flash movie that was made years ago. There were plenty of refutations for such arguments. This guy is a hack and rip off trust me.
If the Government wanted to deceive all of America into thinking a plane slammed into the Pnetagon, I think that they were probably use a freakin airplane. Why he raised the Tomahawk argument, I don't know. Why would they make a plane, its passengers, and its radar signiture disappear just to use another plane to crash into the Pentagon instead? With all the Cameras, people, media crisscrossing the path of the airplane that hit the Pentagon in broad daylight, why would they use a military plane?
The lawn skid mark argument, I love how he used a blurry picture full of smoke to prove that you can't see anything on the lawn. I love how uses bs arguments to confuse people viewing the video using irrelevent facts to support them. Like when he was talking about buildings being on fire causing collapse. First of all, the twin towers collapse because the jet liners stripped the protective materials around supportive beams. The materials are there to protect the beams from fire damage. Second of all, he gave all those facts on Chemistry. Steel melts at this and jet feul burns at that. Useless info. The steel doesn't need to be heated to melting point to collapse. It needs to weaken only a little before it bends under the weight it supports. Third, the Empire State Building was struck by a WWII era bomber. Compare the size, speed, and type of feul with that of a 747, and you'll know why the building stood. And the rest of the buildings he showed didn't have their protective covering stripped off of their support beams. So it was really irrelevent.
I could go on and on refuting all of his arguments, but I don't want to waste my time. Please be very skeptical when you view this. The movie maker did a good job of cropping and editing the movie with deceiving clips and photos. Don't get fooled by them.
