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.

They were adequate to learn to do the job and we didn't have any big surprises in that area. The things that we'd learned about body positioning, arching the back, clearances required, and one person helping another and so on worked just like the real case. There weren't any difficulties in movement through the hatch or with stability on the porch. After getting onto the porch, I came back into the LM and went up around the Z-27 corner, made sure that was as expected and it was. I returned to the porch, got on the ladder, discarded our duffle bag with arm rest and OPS pallets, released the MESA without any difficulty, and descended the ladder just as expected. The first step was pretty high; 3 to 3 1/2 feet. So the initial test # CONFIDENTIAL
