Well, lets see. There was enough evidence to produce an hour long TV show on a major and reliable channel, which is sort of the Canadian version of Discovery. Some were very, very peculiar, such as the crosshair (I don't know the proper name) of the camera being behind and object that was being filmed (the American flag),which is impossible.
This was 2 or 3 years ago, and I can't remember the specifics, but it was a pretty convincing case. That is, if you have no prejudice as to the validity of the claims that a man walked on the moon, which I don't. I try to have as little prejudice as possible and let the facts speak for themselves.
edit: it was on TLC, which is apparently owned by Discovery, and it was broadcast on Discovery itself aswell, it seems.
