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 uncomfortable for a couple of hours with the UCD pushing into my crotch area. This problem goes back to that first suit fit at the factory. ILC is very concerned about the mobility inside a pressurized suit, and I think they went a little bit overboard in cutting that thing on the tight side. I didn't really put the UCD on; you know what I mean. They've got a house UCD up there, and you sort of slap that inside the suit and then you get a fit check. The only time it hurt me was when I actually had the UCD securely held and I was strapped into the couch and my legs were up. The only thing I could suggest is that when anybody goes to the factory, they take their own UCD and put the damn thing on and, during that fit check, go through some kind of an imitation of the watch position with the correct leg-to-body angle which you have in that couch for launch position. Put your own UCD on and see whether that's going to be comfortable or not. I fiddled and diddled with it between CDDT and launch, and it was still fairly uncomfortable for launch; for CDDT, that damn thing almost did me in. Don't let them cut the suit too tight, and try to get a good fit check at the factory. ## CONFIDENTIAL
