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
ALDRIN (CONT'D) that by a couple of seconds. The expected $ V_{I} $ was 35575 and I reported 35579; the H-dot expected was 4285 and I have 4321; and, of course, H-dot was building fairly rapidly and that's not quite a mile a second, so the expected altitude was 174 and we read 176. The EMS was 3.3 plus.
ARMSTRONG Yes, we knew, when the EMS showed only 3 ft/sec off in a 10 000-ft/sec burn, it was going to be pretty good to us.
5. 3 UNSTOWAGE AND PREPARATION OF CAMERAS ARMSTRONG No problem.
5. 4 S-IVB MANEUVER TO SEPARATION ATTITUDE
ALDRIN It was right on schedule and no comment.
5. 5 PRESEPARATION CONFIGURATION
ALDRIN No problems.
5. 6 MCC GO/NO GO FOR PYRO ARM
ALDRIN Well how about that high $ \mathrm{O}_{2} $ flow anomaly that I think the ground picked up?
ARMSTRONG Yes, I guess that's right.
5. 9 S-IVB/IU CONTROL SYSTEM PERFORMANCE ARMSTRONG Good.
