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

COLLINS (CONT'D)	On a couple of marks, when I got 5 balls, I know that I was not precisely centered when I took the mark. So, I think that there was some small bias in the sextant.
6.2 DOFF PGA'S
COLLINS	There were, as far as I can recall, no surprises in doffing the PGA's.
ARMSTRONG	Buzz took his off first.
ALDRIN	We were going to stow that from the back, and I was going to be the last one to put it on. Anyway, you were going to put yours on before I did.
ARMSTRONG	As a result of a day that we spent in the CMS practicing taking the suits off and stowing them in the right place, in the right order, and so on, we decided to put all suits in the L-shaped bags: Mike's in the top, Buzz's suit in the bottom section to the rear towards the upward edge or the head end of the couch, and mine in the lower part of the L-shaped bag in the lower section. That worked fine.
	All three suits did go in the L-shaped bag satisfactorily and could be stowed there. We left them out though for some period of time prior to stowing them to allow them to air out
