... did a show on whether the moon landings were fake or not.
Couple things of interest:
It was nearly impossible to emulate the walking that the images show, without being in moon gravity. Now, NASA may have had a nice moon set on a plane, but that would have been a cool trick - in the 1960s.
I guess that there was left behind a lens (I forget the name of it) that, if you shot a laser at it, it'll return the shot directly to the source. So they went to a lab that "pinged" the moon. Now, granted, the lab could be in on "the secret" so I don't know if that disproves anything - it was equipment sketching a spectrum, not a visible beam of light, that you see.
They also proved that the sand on the moon would allow a footprint, even in the absence of water (the dirt on the moon hasn't been worn by erosion, so its sharp and holds shape better when stepped in by a rude American tourist).
