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.

There were no abnormal dynamics. The thing backed out absolutely symmetrically as far as I could tell.

## DURING EJECTION FROM S-IVB

## 5.29 ADEQUACY OF ATTITUDE CONTROL AND STABILITY

The S-IVB was always very stable prior to, during, and after LM separation. SM RCS plumes had absolutely no effect on visibility or on S-IVB stability.

## 5.32 EVASIVE MANEUVERS

We thought at one time we might be somewhat rushed during that time period. It turned out that was comfortable and we were prepared to do the evasive maneuver. We could have done it 5 or 10 minutes earlier than it was called for. Luckily, it is not a maneuver that is time-critical. I think the present scheme of causing the S-IVB to overburn by
