I have to confess: I've never been able to understand, from looking at the photos of the Pentagon after the 9-11 crash, how a commercial airliner could have been responsible. This site, like so many others, "explains" the confusing photos by claiming that no such plane was really involved.

All well and good -- but what about the passengers? Were they dragged out of their homes by Men in Black and stealthily disposed of? Were their friends and families implanted with fake memories of their leaving on an airplane? Explanations, please.
