According to Dr Edgar Mitchell, sixth man to walk on the Moon - Aliens are real, there has been a cover-up.

One part batshit crazy, one part 'you know it's true.'

The Astronaut, the Aliens, and the Hype | TDG - Science, Magick, Myth and History:

"Dr Edgar Mitchell, sixth man to walk on the Moon, has set tongues a'wagging all over the world with his revelations in a radio interview that Earth has been visited by aliens, and that the government has covered it up (not to mention, 'I think we're heading for real disclosure'). Rick and RPJ covered it over the past couple of days, when it was an 'underground' thing, but now it's hit mainstream - check the frenzied press coverage via Google News.

...NASA's response ('Dr Mitchell is a great American, but we do not share his opinion on this issue.').

It should be an interesting story to follow."

6th man on moon says space aliens are real - Boing Boing:

"On July 23, 2008 Edgar Mitchell was interviewed on Kerrang Radio. Mitchell claimed the Roswell crash was real and that Aliens have contacted humans several times but that governments have hidden the truth for 60 years stating 'I happen to have been privileged enough to be in on the fact that we've been visited on this planet and the UFO phenomena is real'."
