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 Then I thrusted minus X until the DELTA-V counter read minus 100.5. I think I thrusted plus X until it read minus 100.6. The point where the EMS was in error came after that. That's what I don't understand. When I completed the turnaround maneuver, the EMS should have read minus 101.1 and it didn't. It read down in the 90's. At docking, when it should have read 101 plus, it read 99.1. So there is a funny there in the EMS. ## 5.15 HIGH GAIN ANTENNA ACTIVATION ARMSTRONG That took us quite a while. COLLINS You did that later. ALDRIN Yes, we didn't get that done until after docking. ## 5.17 TRANSPOSITION Transposition and docking, in general, worked in flight just as it worked a couple of times in the simulator. I went MANUAL ATTITUDE PITCH to ACCEL COMMAND, and I started to pitch up. After 10 or 20 degrees of pitchup, when it was definitely established that the attitude error needle in pitch was full scale high (indicating that the DAP wished to continue the maneuver in the same direction in which I had started it), then I went PROCEED and MANUAL ATTITUDE ## CONFIDENTIAL
