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 No.
COLLINS We were glad the ground was looking at it. It seemed to be all right to us.
## 7.10 ACQUISITION OF MSFN
ARMSTRONG In the post-LOI, we had a MSFN contact on time and did a P52 option 3 and 2 drift check. Those numbers were reported.
## 7.15 SPS BURN FOR LOI-2
ARMSTRONG LOI-2 was a bank A only burn. I assume this was to conserve nitrogen pressure in the B cell. This was a 17-second burn. Residuals were reasonable 3.3,0,and 0.1. The DELTA- $ V_{C} $ again was 5.2.
7. 17 ORBIT PARAMETERS FOR LOI-2
ARMSTRONG Postburn NOUN 44 was 54.4 by 66.1.
COLLINS Did you want to talk about that orbit being targeted 55 by 65 rather than 67?
ARMSTRONG Yes, I think we made it clear on a number of occasions preflight that we were not in agreement with the change, just prior to flight, to the 55 by 65 orbit. We did not disagree with the intent of what they were trying to achieve; it's just that this did not have the benefit of
