I once heard a radio interview of some guy who swears the lunar landing never happened. It was beyond weird in terms of a conspiracy to fool the American public. In short, you'd have to have a ton of people, governments, and scientist involved to pull off the hoax. And technology too. What it would take to pull off a hoax is more complex than actually landing on the moon... literally. So in a way, the guy and his theory was an advocate of much more genius on the part of the space community. And what is funny is that with every question asked of him and how they could possibly pull off the hoax, the more he just didn't seem to get it that he was talking about some very serious work on the part of the community that was indeed herculean!
