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 Subjectively comparing the weight of the boxes (following removing them from the spacecraft on the carrier), I would say closer to one to ten — just judging the differences in weight and feel of things and the way the masses behaved. One to six gives you the impression there is a much greater difference than that. Now in your own maneuvering around, it doesn't seem to be anything like a factor of six in the ease in being able to do things. It would appear as though the gravity difference was much less. What I'm saying is that it looks like the human can adapt himself to this quite easily. It also appears as though the handling of objects is considerably easier in 1/6g, as we had anticipated. In maneuvering objects around, they do have a certain mass. When they get going in a direction, they will keep going that way as was evidenced when they were coming in the hatch on the LEC. They are fairly easy to manage, but you have to take your time in handling them. 10. 44 LM INGRESS ## ALDRIN Stability and balance: Well, the first step up to the bottom rung no doubt is a pretty good step, though Neil tells me he got up to the third one. ARMSTRONG The third step. ## CONFIDENTIAL
