>some people think a missile hit the Pentagon The strike on the pentagon was not dissimilar from a non-detonating cruise missile hit. >What happened to American Airlines Flight 77, then? A 4-hour presentation given by Khalezov includes 9/11 video of a witness at The Pentagon stating there was no airplane. He later suggests that the planes were acquired by the US government as a cover story so the population would not believe the nation was under nuclear threat. I suppose that because the government heavily regulates the airline industry and is deeply involved in classified ways with the same companies who manufacture these aircraft, it's not inconceivable that some could be acquired for the purposes of a cover-up. Here's a question for you: Why were certain procedures unique to nuclear attacks enacted on the day of 9/11? For example, why was the door to NORAD's Cheyenne Mountain Complex in Colorado sealed if the threat was only hijacked planes?
