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.

don't believe that we were in position to be doing that until after we passed Canaries. Each person is sort of operating on his own. We know we're going about in the various systems checks, and that doesn't fit into a real good timeline.
## COLLINS
An example here on page L2-8, item 4, EMERGENCY CABIN PRESURE valve to BOTH. That check is made prior to anybody's going into the LEB. That's impossible to do; obviously, you have to be down in the LEB to see it. The man who goes down to the LEB — if he goes through steps sequentially as written in the checklist — would start jumping from one place to another back and forth. Some improvement could be made in the order. Now, I sort of got lazy and decided not to fight the checklist world. I just had my own order in which I was going to do them regardless of the order that is in the printed checklist. But to really be precise about it, the following crews ought to look at this little section and get things rearranged to their liking and for a minimum amount of moving around.
## ALDRIN
Yes, well, for example, that step 7 on 2-9: During 20 minutes of ECS postinsertion configuration, we've been doing other things at that time. I don't believe we were in
