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 Thermal loads in the suit were not bad at all; I ran on minimum flow almost the entire time. Buzz found a higher flow to be desirable. This was consistent with our individual preflight experience. I didn't notice any temperature thermal differences in and out of the shadow. There were significant light differences and visibility changes but no thermal differences. The only temperature problem I had (and Buzz didn't have this problem) was with the gloves. I did not wear inner gloves. I chose to go without the inner liners in the gloves, and my hands were a little warm and very wet all the time. They got very damp and clammy inside the gloves. I found that this problem degraded my ability to handle objects and to get firm grips on things. I had cooler levels set on the diverter valve, because it just seemed to be comfortably pleasant that way. In retrospect, it appears that this leads toward a higher consumption of water. I wasn't fully aware that when you are on higher flow, you are going to be pumping more water overboard. It was not clear to me preflight that it did have that effect on your water consumption. I certainly could have operated at lower levels much sooner without ## CONFIDENTIAL
