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 ## 8.0 LUNAR MODULE CHECKOUT THROUGH SEPARATION ## 8.1 COMMAND MODULE ## 8.1.1 CSM power transfer ## COLLINS I recall that went without incident. Prior to this time, the CSM had been providing power to the LM heaters, and you could watch the load cycle on the service meter as the heaters cut in and out. They were always within limits. Eleven amps is supposed to be the maximum and I don't think we ever went over two-thirds of that. ALDRIN I think it's worth while to point out that we didn't jump ahead of the timeline by getting up early. I think we felt confident that the time we had was sufficient. ARMSTRONG We had 2 hours before we went in from wakeup. I think it probably worth mentioning that, none of us got as good a night sleep that night as we had the previous night. I'm sure it was just that the pressure was beginning to build at this point. We were coming up on DOI day. We got 5 to 6 hours sleep that night. I guess I should have expected that. ## 8.1.2 Updates ## COLLINS They updated us with the fact that Al was 500 feet above the landing site. That didn't seem to turn anybody on ## CONFIDENTIAL
