An excerpt(1) from the British documentary, Apollo 11: The Untold Story is now posted on Google Video. In it, astronaut Buzz Aldrin, speaks about "something out there close enough to be observed." While the documentary infers that it was a UFO, Aldrin recently told C2C that his mystery sighting turned out to be something called "high velocity Z particles."
