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 ## 6.24 RADIATORS COLLINS We never flowed through the secondary radiators because the primary worked fine. The cabin temperature (translunar) was slightly warmer than we would like it, although the gage readings were quite cool. We were running 60 degrees cabin temperature and 57 degrees suit temperature. ARMSTRONG High 40's in the suit and low 60's in the cabin. COLLINS Yet we were warm in spite of those low numbers. ## 6.25 CM/LM DELTA PRESSURE Well, the LM pressure would slowly decay, but remain well within tolerance. I don't have any good numbers. It was a tight LM. ## 6.26 RE-ESTABLISHING PTC We've already discussed that, I think. We always used 0.3 deg/sec roll and we never tried the 0.1. It would be advantageous, in regard to antenna switching if stability is satisfactory, and 0.1 deg/sec would probably be a better mode than 0.3. It would also save some gas. However, we did not investigate that. Perhaps that ought to be something for future flights to look into. I think that theory has been mentioned to FOD. ## CONFIDENTIAL
