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
Neutral buoyancy simulation as a training aid post-mission evaluation of problems that he encountered during his Gemini IX-A EVA. NASA then modified the contract to include pre-mission training of Gemini XII astronaut, Buzz Aldrin. Astronaut Cernan also participated in this pre-mission training, as he was in a backup role to Aldrin as pilot of Gemini XII. Aldrin trained for the original Gemini XII EVA version which was then revised to eliminate the task of using a manned maneuvering unit. Aldrin returned to the McDonogh facility and trained for the final version of his EVA. NASA considered the flight EVA to be a total success, and Aldrin again
