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 ## 3.0 POWERED FLIGHT ## 3.1 S-IC IGNITION ALDRIN There really wasn't much of a cue at all that I could recall. I can't remember feeling much of anything before T zero. How about the rest of you? COLLINS No. It was very quiet. You could feel the engines were starting up because there was a low amplitude vibration. ## 3.2 COMM AUDIBILITY AT IGNITION ARMSTRONG COMM audibility at ignition was good. Noise vibration intensity prior to release was minor. ## 3.3 NOISE/VIBRATION INTENSITY, SHOCK AND ## CREW SENSATION PRIOR TO RELEASE COLLINS There was low noise, moderate vibration. I'd say light to moderate vibration. I didn't really notice much vibration until we released. Crew sensation prior to release is just about what you'd expect from Titan or from previous crew briefings on the Saturn V. It was quite mild prior to release, I thought. ## CONFIDENTIAL
