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.

I tried to do this, not because there was any real requirement to do so, but just because I felt that it would be a good initial condition for an abort if I were able to see the LM in the sextant. ## 9.1.13 Lunar surface flag ## COLLINS After the LM landed, I set the surface flag -- There was no evidence ever of any flash of specular light or anything like that off the LM. The LM, at distances of 100 miles, or so, is just another little light, little lunar bug that was indistinguishable on the background surface. The surface is pockmarked with little irregularities — light spots, dark spots — and with P20 driving so as to hold that background surface relatively constant and at those distances, you just can't pick the LM out. ## 9.2 LUNAR MODULE ## 9.2.1 Preparation for DOI ALDRIN It was 40 minutes before DOI that we were scheduled to- ## CONFIDENTIAL
