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 It had been exposed to the boost environment, too. I don't know how stuff would get under there with the BPC on. The BPC doesn't leave until you're darn near in a vacuum. Despite that, I thought that perhaps there was some odor associated with the high temperature of boost that had somehow gotten through the BPC and through that little tunnel vent line into the tunnel area. It sure smelled, and it smelled a couple of days later coming up on LOI. When I went in to activate the LM, the odor was just as strong. All these latches made. Latch number 6, which is the one that had acted up a little bit down at the Cape during tests, was the only one that needed one actuation to cock rather than two. Other than 6, all the others said that they were going to require two pulls to cock and they did. All that hardware worked well. We followed the checklist. We extracted in CMC, FREE, and then went to DAP control and fired the aft thrusters for 3 seconds. We went to CMC and DAP control 5 seconds after spring actuations. Neil and I both read a memo put out by MPAD, saying that for some failure modes you weren't supposed to do that; instead use SCS control. Ken Mattingly and I spent a lot of time the last couple of days before the flight ## CONFIDENTIAL
