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 COLLINS Yes. I recall I gave you some ranges. I didn't write them down. ALDRIN It agreed with our values very closely. COLLINS And they agreed with my state vector. I just wrote down one value which was fairly close to yours. When I had you at 0.72 miles on VHF ranging, my state vectors indicated 0.62. ALDRIN That was close. Did we get that alignment finished? It seemed to me it took a little longer. ARMSTRONG Yes, we took five marks on each star, and it did take us quite a while. ALDRIN Yes, I would like to emphasize to subsequent crews to allow lots of time in their timelines when they're doing the alignments. We made a practice early in training of leaving the TTCA switches disabled as much as possible, and the direct coils 4-jet active. I'm not sure everyone understands why you do that. It's a good sound thing, I think, to keep as many hand controllers out of the loop as you can. # CONFIDENTIAL
