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.

ARMSTRONG (CONT'D)	MINIMUM IMPULSE and it was extremely difficult to hear the thrusters firing. It was impossible to read an effect on any indicator in the cockpit.
COLLINS	This is with helmet and gloves on.
ARMSTRONG	Helmet and gloves on. So we were pleased when the ground said they could, in fact, see the thrusters firing. We did have to repeat one which they didn't see.
ALDRIN	I don't recall why we had the helmets on at that point.
ARMSTRONG	We didn't take them off?
COLLINS	We took them off and we put them back on.
ALDRIN	That should have been with at least one man with his helmet off so he could hear it.
ARMSTRONG	Right.
COLLINS	Well, on the other hand, if you scheduled it over the States and the ground verifies it, you don't much care.
ARMSTRONG	I was satisfied that we did, in fact, prove the point that we wanted to prove.
