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 that when I put the feeds to close they would indicate open momentarily. The crossfeed was cycled again to close. I turned the camera off and proceeded with the switch configuration. Cycling the CWEA circuit breaker did, in fact, turn off the descent Reg warning lights. We read the sine and cosine out of AGS (and I'm sure they copied that down) and went immediately into recording the AGS gyro coefficients. I'm sure that these were the same numbers that we finished up with, but it might be a good time to check. Then we went to cabin on the regulators and took our helmets and gloves off. Then we started in with the initial gravity alignment. I don't have the first NOUN 04 that we got. I didn't record that one, but it was fairly large. I've seen so many of them in simulation that I just can't recall what that number was. ## ARMSTRONG I am sure that it was recorded on the ground. After the recycle, it was 00001. We asked them about recycling and they said affirmative. Got a star-angle difference of 00015 and some torquing angles, which showed a fairly good change. I guess the pitch is the ## CONFIDENTIAL
