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

4. 10 DOCKING PROBE

ARMSTRONG	I think they're attempting to recall anything that might have gone abnormally.
COLLINS	There were no findings in that docking probe.
	4.12 COMMUNICATIONS
ARMSTRONG	Communications were more or less in and out in earth orbit. Sometimes there was quite good S-band through the various stations; other times, it was only medium.
	4.14 COMMENTS ON EARTH-ORBITAL OPERATIONS
ARMSTRONG	Any comments on the earth-orbit operations?
COLLINS	I think, in general, that's a very nice timeline. We hammered away at it enough to where we're only checking those things that really should be checked and there's plenty of time available to check them in a leisurely fashion. I think that's a nice timeline.
ALDRIN	How about the alignment? On the Saturn?
COLLINS	The platform alignment?
ALDRIN	Yes, torquing angle we got from the ground and the alignment they gave us -
COLLINS	Yes, I didn't know what to say about that. I think that's probably within normal tolerance.
