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 COLLINS Because of transposition and docking and P23, we started off behind on RCS and we stayed slightly behind on RCS. The other consumables, oxygen and hydrogen, were within limits. What about LM consumables? ALDRIN I guess we went to bed according to the flight plan. How many hours did we have scheduled? ARMSTRONG We had a 9-hour rest period scheduled starting at 85 hours. ALDRIN I think the reason we were able to be in position to take advantage of the rest period at the beginning of it was because we had already gotten used to the LM operation. ARMSTRONG I guess we knew all along that that could be the problem on our timeline, just as it could have been on 10. Any-time you get hung up in that DOI day on LM systems, you're not going to make it. We had that same strong inclination to try to be ahead and try to understand the LM as best we could before that time period. ## CONFIDENTIAL
