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.

Prior to power descent, the problem was obscured from my mind, but it was aggravated somewhat by the restraint pulling down and forward.

ALDRIN I was able to lean over and make entries on the data card without pulling it down; but as you can see, when you do make entries on them, you make them sideways. ARMSTRONG The cut-off was a guided cut-off. What about the residuals? ALDRIN We burned both X and Z, and I'm sure they weren't in excess of .4. ARMSTRONG It was less than 1 ft/sec, but I don't recall the tenths. 9.2.6 Trimming residuals ARMSTRONG It's probably worth noting that the flight plan at this point does not adequately reflect the time requirements of the flight. I think the DOI rule in the flight plan says, "Trim VX residuals." ALDRIN So does your checklist. ALDRIN So does your checklist. ## CONFIDENTIAL
