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.

points during the docking. It is discernible if you really look closely. At the end when you need it, it's more visible than it is 20 to 30 feet out. I would say that the COAS is marginable, but satisfactory.
5. 24 CABIN PURGE AND LM/CSM PRESSURE EQUALIZATION
## COLLINS
I believe all that went just about exactly as per the numbers
## ALDRIN
We went PRESSURE EQUALIZATION valve to OPEN. Where it says go to A, we went to 3.8. That's where it stabilized. Repres sure $ \mathrm{O}_{2} $ only brought it up to 4.4. That gave us a DELTA-P of near zero. There wasn't any cycling back and forth. There was just one cycle open and that's as far as it went.
LLINS That cycling back and forth only applies if you have a problem when you don't have in the full volume of the LM.
5. 25 CONFIGURING FOR LM EJECTION, DOCKING PROBE,VENTING LATCHES, UMBILICALS, POWER, AND TEMPERATURE
## COLLINS
Okay. The only funny here was when I opened the hatch to get into the tunnel, there was a peculiar odor in the tunnel. This odor was not exactly the same as burned electrical insulation.
## ALDRIN
You commented that the wiring in the cables seemed to retain this odor.
