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.

## CONFIDENTIAL

COLLINS (CONT'D)	4 percent differential. All this was a little confusing to me. It sounded as if we got shortchanged in oxygen tank number 1. I'm not sure if that's true, and it even occurred to me that there might have been a slight leak in tank number 1. I'm sure that there wasn't, or they wouldn't have launched us. A few words on that subject would have been nice. I think as a general rule if the loadings are not nominal, it would be nice to let the crew know that they're a little off nominal. It sounded like we launched in violation of the launch mission rule.
COLLINS	Differential between oxygen tanks?
ARMSTRONG	Yes. It was 5 percent, and it sounded like the mission rule was 4 percent MAX. And I was perfectly happy to launch with that if that was the only problem. I didn't want to bring it up on the loop and make a federal case out of it. On the other hand, it would have been nice to know.
ARMSTRONG	It only took 1 hour and 15 minutes to get through a perfectly normal launch with no problems.

COLLINS We started late.
