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 So, I think some explanation and expansion in those pages in the checklist is in order. ## ARMSTRONG It's probably worth noting here, while we're thinking about it, there seems to be some advantage to writing a program to do this job. At least it should be considered, rather than the one we're using at the present time. It could obviate many kinds of minor difficulties that we didn't mention until now. ## COLLINS ## 6.14 EASE OF HANDLING OPTICS AND SPACECRAFT FOR ## NAVIGATIONAL SIGHTINGS With P23, as I practiced it in the simulator and made use of the AUTO optics to maneuver the spacecraft to each star substellar point, the flaw in this technique is that the spacecraft roll angle is unconstrained in that with large trunnion angles, the computer may pick a roll attitude which causes the star to be occulted by the LM structure. Now, the flight planners came to me a couple of weeks before the flight and said that to get around this disadvantage of the AUTO optics, they wanted to use ground-computed angles to which to maneuver, and then these ground-computed angles would have a roll angle which would assure that the star would not be occulted by the LM structure. And at that time, I told them that all my ## CONFIDENTIAL
