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 finally settling down. During the process of doing this, I believe two of the four corners came in contact with the surface and picked up a light coating of surface material. I'd say the triangle that was coated might have been 2 inches on one side and maybe 1 inch on the other—a very small triangle. So I don't think there was much degradation at all on the surfaces with that particular coating. I made one final inspection and, when I left it, the BB was still sitting on the edge. Neil came by with the camera to photograph it and he looked at it and found the BB was sitting right in the center of it. I have no explanation for that at all. ## ARMSTRONG It would have been nice to have a big rock table to set those packages on, but there wasn't any. The area where they were placed was a ridge between some shallow craters. I think we have reasonably good pictures of those ridges. They have this same kind of soil consistency as the surrounding area. The packages were in essentially soft material which allowed us to jiggle them down and get them reasonably well set into the sand, but there is no knowing whether they will stay there for a long period of time or might slowly settle. ## CONFIDENTIAL
