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 ## 5.0 TLI THROUGH S-IVB CLOSEOUT ## 5.1 TLI BURN MONITOR PROCEDURE ARMSTRONG The procedure went very well. COLLINS Except yaw. ARMSTRONG No, the yaw was perfectly on, but the pitch showed approximately a 1-1/2-degree bias from the value that we would have expected. That is to say, with the ORDEAL set in a LUNAR/ 200 configuration, and being at the proper point on the minute each minute prior to ignition. The pitch attitude was indicating about 1-1/2 degrees higher, that is, 1-1/2 degrees to the right or plus 1-1/2 degrees from zero. We expected approximately zero. I think this would be wise to look at that carefully with DCPS training guide with respect to the adequacy of that procedure and see where that little bit of difference occurs. Other than that, the TLI monitoring went just as expected. ## ALDRIN But that was an instrument that was used to make changes if we were in control. The closing of the loop was really the observation of the H-dot which was surprisingly close. At each 30-second period, we closed the DSKY and looked at the H-dot and it was amazingly close. Of course, there get to ## CONFIDENTIAL
