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.

As soon as it started toward the -100, when it was around -120, I was convinced that it was in the upward swing toward INCREASE. I threw it to FULL INCREASE well before the normal ground rules required, and the valve went to MAX. Despite the fact that it was in INCREASE, the needle eventually went into the INCREASE position. I don't think we got over a 100. At the end of the burn we were three- or four-tenths behind. ALDRIN Even by leading it as much as I did, I still ended up being a little bit behind. That was pretty small compared to what it could have been. ARMSTRONG How about the burn itself, Mike? COLLINS It was just about nominal. ARMSTRONG Buzz, give the pad value for burn time. ALDRIN 6 02. ARMSTRONG Burn time was about 5 57. So it was 5 seconds ... ALDRIN Yes. Fairly early in the burn, we could tell that. COLLINS I remember, you were predicting that. ALDRIN Three or 4 seconds early is what we predicted. COLLINS Start transient was very small, and steering was extremely quiet and accurate. The chamber pressure, which we had ## CONFIDENTIAL
