Anyone who holds on to even a SHRED of hope that the Alien Autopsy is real just ask yourself what I asked in my summary. Even by 1940's standards, the video tape was laughably horrible. The a government agency was trying to document an event of this importance, they would have used the best video equipment available at the time. They also would have had someone with some intelligence in handling the camera. Therefore the footage would not be blurred virtually EVERY time something important happens, and would not keep going out of frame. This was just another sad attempt by Fox to give credibility to the ridiculous. I don't remember the name, but another show completely shot down all the 'experts' contentions that it was real. Most notably these Hollywood special effects 'experts' (why not get Tom Savini if you want the best?) who claim the alien body would be virtually impossible to fake. That movie actually recreated the autopsy very easily with things available to the original filmmakers.
And of course there is no question of 'If the aliens made it here in the 40s, why did they suddenly STOP coming?' Or if you want to believe that they didn't, then how come there hasn't been a single true sighting since? distant lights in the sky don't count. Apparently they came all the way to earth at Roswell. With EVERYONE having a camcorder these days, we would see actual footage of ships, not just random lights in the sky.
Bottom line: If you want a good laugh, and you have nothing better to do, check this out. If you start believing it for a second, seek professional help.
