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 with the EVA and it was sometime in here that Neil called to ground and let them know that. There were two factors that we thought might influence that decision. One was the spacecraft systems and any abnormalities that we might have that we'd want to work on, and the second was our adaptation to 1/6g and whether we thought more time in 1/6g before starting the EVA would be advantageous or disadvantageous at that point. Basically, my personal feeling was that the adaptation to 1/6g was very rapid and was very pleasant, easy to work in, and I thought at the time that we were ready to go right ahead into the surface work and recommended that. ## ALDRIN Now, we estimated EVA at 8 o'clock. I think that was a little optimistic. The ground recognized that, because they said, "Do you mean beginning of PREP or beginning hatch opening?" And all during this time, we could tell that Mike was kept busy each pass, doing P22's trying to find where we were. ## CONFIDENTIAL
