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 Maybe. 6.27 HIGH GAIN ANTENNA PTC REACQ CHECK COLLINS We did it coming back. ALDRIN When it worked, it worked like a charm. There were a couple of times when it didn't seem to want to work. 6.28 OPTICS CALIBRATION COLLINS Optics CAL the next day worked fine. 6.29 FUEL CELL PERFORMANCE AND PURGING COLLINS The fuel cells performed perfectly. Purging didn't present any problems. We followed the checklist on the heaters and they worked normally. 6.30 LM AND TUNNEL PRESSURE COLLINS LM and tunnel pressures were normal. 6.31 LATCH VERIFICATION COLLINS Latches, as I say, were all verified. Latch number 6 required one actuation to cock. That was the only anomaly and it was within the realm of normal. 6.32 INSPECTION OF TUNNEL MECHANICS COLLINS I'm not sure what that means, but everything in the tunnel was normal. ## CONFIDENTIAL
