This is the NASA Apollo 11 Technical Crew Debriefing dated July 31, 1969, prepared by the Mission Operations Branch, Flight Crew Support Division, and released by the U.S. Department of War. The confidential excerpts record Armstrong, Aldrin and Collins describing an unidentified bright L-shaped object seen about a day from the Moon, which they could not identify and suspected came from the spacecraft. They also describe light flashes inside the cabin and a bright light on Earth later attributed to reflection off a lake.
## CONFIDENTIAL ## ALDRIN Sometimes a minute or two would go by and then you'd see the two within the space of 10 seconds. On an average, I'd say just as a guess it was maybe something like one a minute. Certainly more than enough to convince you that it wasn't an optical illusion. It did give you a rather funny feeling to contemplate that something was zapping through the cabin. There wasn't anything you could do about it. ## ARMSTRONG It could be something like Buzz suggested. Mainly a neutron or some kind of an atomic particle that would be in the visible spectrum.
