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 ## 3.33 LET AND BPC JETTISON ARMSTRONG Tower jettison - you could watch it go. There wasn't any question about it. 3.34 GUIDANCE - INITIATE ARMSTRONG Guidance initiate was about as expected. The S-IVB staging and engine cut-off were... ALDRIN Anybody notice any exhaust coming back on the windows when the BPC went? It seemed to be a pretty clear separation. ARMSTRONG I didn't note any. I wasn't looking out the window at that point. COLLINS I was, and I didn't notice any. Those windows, 2 and 4 were clear. They didn't have any deposits on them. 3.37 S-II/S-IVB SEPARATION COLLINS The staging sequence is a long slow one. I'm sure it was about equal to the simulated values we were used to. It seems like a long time in flight to get the S-IVB ignited. The S-IVB guidance was as expected. ALDRIN Any comment about the gimbal motors coming on? ARMSTRONG The motors were put on at 6 minutes and all came on. ## CONFIDENTIAL
