All the "official" sources claim it really happened, of course. But after careful examination of the available footage, I have to say I've become very skeptical. It just doesn't seem possible within the laws of physics as currently understood. My personal, tentative hypothesis is that there's some kind of combination treadmill-pulley system involved. But I leave it as a question to you: do you honestly believe that this individual (parenthetically a known drug-user and suspected child abuser) was somehow able to defy all known principles of human locomotion? Or is it, as some bloggers believe, a massive cover-up by the U.S. Federal Government? I'm not saying yes or no, I'm just asking questions.
