It has been said that during the Apollo 11 mission, Buzz Aldrin saw and reported UFO's in space. The story has never been confirmed or acknowledged by creditable sources, but now you can hear it from Buzz's Mouth!
According to Buzz, Apollo 11 wans't alone in space. A strange object was traveling near the spacecraft, and the crew had a clear view of the unidentified object. Buzz and the rest of the crew were weary about reporting the sighting to Mission Control, so they requested the position of the S-IVB (final stage of the rocket that has been propelled away 2 days earlier). Mission Control replied that the S-IVB was around 6,000 miles away.
To this day, the object that Buzz saw has never been identified.
