Ask them where a 757 and all the passengers and crew are (including a reporter and wife of the Counselor General of the United States), and how such a conspiracy can be kept secret when we can't even keep WAR plans secret....
ETA: You also might want to ask them why it is that NO ONE can decisively say they saw a missle. After all, it only flew right over a major metropolitan area and over an interstate, right?
Also, the people who were watching that video "over and over" in shock. Why haven't they spoken about it? Were they threatened with joining the vanished compliment of Flight 77?
I've seen 2x4's blow perfect holes in concrete walls during hurricanes. Don't you think a plane travelling at 530 miles per hour could do the same?
The fuel burned up. See that smoke? That's the FIRE, guy!
When something goes over your head at 530 MPH, you will swear it sounds like a missile, ESPECIALLY if you've never had a missle fly over your head or, for that matter, an airliner doing 530 MPH. People are used to seeing planes flying at just over 100MPH.
So the students "couldn't fly", heh? How much skill does it take to push throttle levers forward and aim a plane at a BIG building?
Initial reports at the WTC claimed "small commuter plane" as well. I guess that means that WTC 1 was hit by a missile and WTC 2 was hit by a remote-controlled 767?
I don't recall a big hullabaloo over the fact that windows in the WTC survived the initial impacts, or that aircraft wreckage had been found in NYC. Why do so at the Pentagon?
The WTC towers were thin steel shells compared to the squat stone and multi-ring construction of the Pentagon. If the WTC planes were practically vaporized, why would Flight 77 survive intact?
Heat melts aluminum, especially in a closed stone structure acting as a blast furnace.
So a funny blotch in a DOD camera photo is a missile? Funny, but that blotch is in the exact location of that gas station they mention......
etc., etc.......
You will never be able to rebutt it, because the people who produced it won't care. It's just like the idiots who believe we never landed on the moon....
