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 ARMSTRONG stars, Acrux and Antares. The torquing angles were about 0.3 degree. ALDRIN Yes, and they sure didn't instill a lot of confidence. This was the last alignment we were going to have, and we changed what we had by 0.3 degree. I guess that's to be expected, but I was sure hoping to have smaller ones than that. This indicated the kind of drift we had from the last alignment from the command module, and it was my understanding that these alignments were quite good better than these torquing angles would indicate. ARMSTRONG We're interested in finding out what the drifts were there; whether that was just an inability to calculate any biases and put them into the computer so that you could improve the platform up to what we normally would expect. ALDRIN We had a manual lockon with the radar before we did this. ARMSTRONG Yes. ALDRIN We had P20 standing by, but we didn't use it at all. ARMSTRONG We had a manual lockon and our radar needles and COAS agreed very well. This was your first chance to look at the transponder and all that stuff in operation. ## CONFIDENTIAL
