Buzz Aldrin "First on the Moon: The Untold Story", Aldrin told an interviewer that they saw an unidentified flying object. He told David Morrison, a NASA Astrobiology Institute senior scientist, in 2006 that the documentary makers omitted the crew's conclusion that they probably saw one of the four detached spacecraft adapter panels. Their S-IVB upper stage was away, but the four panels had been jettisoned before the separation maneuver so they would closely follow the Apollo 11 spacecraft until the first mid-course correction. When Aldrin appeared on "The Howard Stern Show" on August 15, 2007, Stern asked him about the supposed UFO
Buzz Aldrin sighting. Aldrin confirmed that there was no such sighting of anything deemed extraterrestrial and said they were, and are, "99.9 percent" sure that the object was the detached panel. In an interview with the Science Channel, Aldrin mentioned seeing unidentified objects, but according to Aldrin his words had been taken out of context.
