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 As was reported, we broke one circuit breaker with the PLSS and we depressed two others, one on each side, sometime during the operation with the PLSS on the back. So that's an area that we still need to improve on to be able to have confidence that the integrity of the LM itself won't be jeopardized by the operation with the PLSS on the back. ALDRIN We had problems with this one particular electrical connector, the one that joins the RCU to the PLSS, ever since the first time we'd ever seen it. ARMSTRONG It's about a 50-pin Bendix connector. ALDRIN It's just very difficult to get the thing positioned properly so that the three pins on the outside, the three little protuberances, will engage in the ramp so that, when you then twist, it'll cinch on in. That must have taken at least 10 minutes. The problem was not with mine, but in hooking up Neil's. I can't say that there was that much difference in the many times that I tried it unsuccessfully and the one time it did go in correctly. It appeared to be squared away each time. CONFIDENTIAL
