NASA via ibiblio · 1969-07-31 · 251 pages · text by GLM-OCR

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

ALDRIN	Subjectively, the first 10 to 12 seconds until tower clear took longer than I thought it would. I would have thought a long 10 or 12 seconds would have been over just like that.
COLLINS	It was a long, long time before anybody gave "Tower clear."
ARMSTRONG	It was right on time. I was looking at the event timer.
COLLINS	Was it 14 seconds - something like that to tower clear?
ARMSTRONG	I'd say 12.
ARMSTRONG	I thought that the COMM came through quite clear.
ARMSTRONG	Instrument observation was no problem during this time. In fact, some were a lot better because the lighting in the cockpit is better than in the simulator.
ALDRIN	But we all agree that there was a decrease in the vibration, oscillation, or rumbling that could possibly be attributed to reflections off the tower.
ARMSTRONG	I think maybe it's just reflections off the ground.
COLLINS	Ground reflections.
ARMSTRONG	It goes away at about the tower-clear time.
ARMSTRONG	I thought they were.
