Assertions are not facts. The video is not "proof." It's evidence. Just because you say that the reconstruction in the video is bogus does not make it so.

Regarding your comment about helmet size relative to the flag, it is irrelevant till to you show the math, based on field of view. The question is "how close was the astronaut to the flag?"

We have all sorts of evidence - not proof, but evidence - that men walked on the moon. The entire case of the moon-hoaxers rests on disputing that evidence. They do so with assertion and with misrepresentation of science.

It does make me wonder (just a little) whether any of the hoaxers has any significant training in science.
