Apollo 11 astronaut Buzz Aldrin wrote in his autobiography Return to Earth: I am a very direct person: when I have a goal, it is stated. He underlined this point of view with a right to the jaw of a conspiracy crackpot who wouldn’t stop badgering him with a bible in 2009. No charges were filed as it was determined that Aldrin was provoked.
Funny side of an astronaut!
Buzz also believes he saw aliens on the Apollo 11 mission: http://www.youtube.com/watch?v=XlkV1ybBnHI
