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 but it was static at that point. We ran through the circuit breakers but couldn't seem to get it moving again. The ground suggested that we turn it off which we did, but when we turned it back on we got all nines. You could change the last digit with the digit sequencer. We turned it off for a while and turned it back on again and it worked after that. We gave them an E memory dump; got a new ascent pad or the CSI pad, for T-3. We then proceeded on with the option 3 alignment. Continuing through the checklist, looking at switch settings, and circuit breaker cards, we found ourselves 10 minutes to go and essentially up on the checklist. At that point, we had to start pressurizing the APS if we were going to launch, so we read through the remainder of the simulated countdown and decided that there wasn't any point in sticking with that timeline any further. So we terminated the simulated countdown and went to the initial powerdown sequence. We had discussed among ourselves the possibility of evaluating, during this first 2 hours, whether we wanted to go on with the rest period that was scheduled or to proceed with the EVA preparation. I think we had concluded before the end of the simulated powerdown that we would like to go ahead CONFIDENTIAL
