People can maniplulate anything. I just posted the link because it was of interest. I fully believe it was a plane.
Relative to the US and World Population, few people have been to the Pentagon to dispute the plane size on those pictures. If there was a picture of my head floating in the sky on those pictures, would that mean that I was there? The author of this page would probably think so.
I do find it amazing how people can skew anything to make it say what they want though.
