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.

You may want to say some things about that undocking and stationkeeping in regard to who was going to thrust, how it worked out, and what it did to our state vectors. ALDRIN We do want to go back and review some LM activities. ## ARMSTRONG Let's go back to the tunnel closeout. As I remember, you were clicking along in good shape there, but we were well ahead over in the LM. We were, in fact, waiting on CMP to get this whole long series of things done. That was completed by clearing the tunnel and getting that ready for us to go. This is a time period when the LM and command module activities are interrelated ## CONFIDENTIAL
