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.

## CONFIDENTIAL probably a matter of a few seconds after being informed that the LM had not made the burn. ## 9.1.11 Monitoring and confirming LM DOI After I went to POO, I lost the LM. This was a couple of minutes before PDI ignition. I just went ahead open loop. I followed my attitude timeline in hopes that I could see the LM again. I did my pitchdown maneuver that the flight plan called for. I did that as a VERB 49 maneuver, and it worked fine in that I had a good unobstructed view of the lunar surface, including the landing area and all that; but again I never saw the LM, so for future flights, I don't really know what to recommend. At the beginning of PDI on this flight, the LM was 120 miles in front of the command module, and touchdown was like 200 miles behind the command module; so the geometry is changing extremely rapidly, and there is no automatic program in the computer for helping you track. You had to abandon P20 prior to PDI, and I don't really have any helpful suggestions. The only thing I can say is to be aware of the fact that when P20 is terminated, the LM is going to depart very abruptly from the sextant field of view. ## CONFIDENTIAL
