As I've mentioned elsewhere on this forum, Ralph Rene was a Mensan, before they kicked him out. Rene is one of the moon hoax "experts", having written a book where he smugly points out all the allegedly fatal flaws in the Apollo program. Mensa disowned him after he wrote a book in which he claimed, despite any relevant education on his part, that both Einstein and Newton were charlatan physicists.

Question 4 applies to Rene's major thesis, which is that the radiation in the Van Allen belts and beyond would have cooked the astronauts instantly.

Who was it who said, "I would never belong to an organization that would have me as a member"?

My favorite quote relating to Mensa comes from Will Rogers: "We're all ignorant. We're just ignorant about different things."
