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 average these up and we would put them in. We'd use either spiral or cursive first, whichever appeared to be convenient. I think this averaging technique worked out better than letting the computer do it, because it would have amounted to a considerable rotating of the spiral and cursive reticle field back and forth to make one spiral, then a cursive, then a spiral, and do a recycle. There is the option, however, to do one or the other. This was a REFSMMAT alignment. The torquing angles were fairly large, the star-angle difference was 00007 which preflight was the expected value of a two-star alignment. Torquing angles were very close to 0.7 in all three axes, which indicated that the platform did drift a fair amount during that time period. We then did the P22. I had hoped at that point to use the AGS to tell me where the command module was, but unfortunately we didn't update the AGS with the latest PGNS state vector so it wasn't giving us good range and range rate. I would recommend doing that, if anyone does a P22 in the future, because you can't use the PGNS to tell you what the range and range rate are. And you can't use the radar because it's not going to lock on until it gets to 400 miles. But the AGS gives ## CONFIDENTIAL
