NASA via ibiblio · 1969-07-31 · 251 pages · text by OCR

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

it mounted; however, I didn't find that the weight of the camera was as much a hindrance to operation as preflight simulations indicated it would be. There is no doubt that having the mount frees you to operate both hands on other tasks. The handle is adequate to perform the job of pointing the camera. I don't think we took as many inadvertent pictures as some preflight simulations would have indicated. It seems as though, in all the simulations where we picked up the camera, we always managed to take pictures. I don't think that was the case in this mission as much as we thought it was going to be. We'll know if a number of the pictures taken are pointed at odd angles.

I found that the shaft extended and locked back into position very easily. It folded out, deployed, and unrolled. I was able to hook it in the bottom catch without any undue shifting around. In putting it in the ground, it went down about 4 or 5 inches. It wasn't quite as stable as I would have liked it to have been, but it was adequate to hold it in a vertical position. I could make the adjustments so that it was perpendicular
