This is Volume 1 of NASA's Apollo 11 Technical Crew Debriefing, dated July 31, 1969. The Mission Operations Branch of the Flight Crew Support Division at the Manned Spacecraft Center in Houston prepared it, and it was originally classified Confidential. In it Armstrong, Aldrin and Collins go phase by phase through suiting, launch, powered flight, Earth orbit and lunar surface activities. They comment on suit fit, vibration, checklists, lunar dust, footing and poor sleeping conditions in the lunar module. A section titled Visual Sightings appears in the table of contents.

# CONFIDENTIAL weren't. Another funny was that there were ground- switching problems where the thing was not receiving a proper signal. ## ALDRIN I remember one time the ground said go ahead and turn the high gain off. I complied and we lost COMM. I don't think they expected it; the next time they had control, we were on OMNI at that time. It wasn't at all clear to me at all times who had control and who was running the show. ## COLLINS That's right and it was a great temptation to go to command reset to make sure that we had control, except that that threw six or eight other switches that we were reluctant to change. I suspected at times that it was not working properly. I never absolutely caught it mal-functioning. I think those suspicions mostly had to do with the fact that we didn't have control of it or the ground had some sort of a sighting problem. ## ARMSTRONG The confusion in my mind often was that I wasn't really sure what our configuration actually was. You can't tell by the switches and trying to interpret what you see in terms of the displays you have available and what you hear ## CONFIDENTIAL
