This is a preliminary transcript of the Gemini 7 technical debriefing, dated December 23, 1965, from the National Aeronautics and Space Administration. It was made from tape recordings of the crew debriefing held December 19 to 21, 1965 at the Crew Quarters, Cape Kennedy, Florida. In it, Frank Borman and Jim Lovell go through countdown, powered flight, insertion, station keeping with the booster, systems, experiments and training. The table of contents also lists a section on visual sightings during orbital flight.
From the source:Release of 2026-06-12 Incident: December 19-21, 1965, Cape Kennedy, Florida. This document is a preliminary transcript derived from voice recordings of the Gemini 7 flight crew debriefing conducted December 19-21, 1965, at the Crew Quarters, Cape Kennedy, Florida. Lights and flashes are mentioned and there is discussion about having proper illumination for vehicle docking. Borman and Lovell discuss celestial and terrestrial observational anomalies and note sightings of Mercury, meteors, aurora, and lightning. They also discuss not being able to see any stars once the Sun comes up.

29 and having the HF/DF on. I'.m not sure what kind of data they got but I hope they got so.mething. The first one we had to do on the lKJRIZ.AN SC.AN; it took so.me fuel and I wonder really if it was worth it. Borman At about 166,40 we noted our drift rate picking up and we finally determined this was from the water boiler venting. It resulted in a left yaw rate and this continued periodi cally throughout the mission. It certainly would not be objectiona.l if we had fuel to counteract it. During a night period, in which we didn't do any attitude control at all, I timed the rates during the 13th day, and when we woke up they were about 7 degrees per second. I timed them around the horizon and came up with 7 degrees per second. About the only thing you can say about it is that it requires fuel to stop it. It occurs primarily in left yaw and left roll. Lovell There are two things in the s/c that causes the yaw left for so.me reason. Gus first noticed it and I think it is characteristic of the s/c. One is the water boiler and the other is,every tie you turn off the power it fires two thrusters that give it a left yaw. The same two all the time. Borman We tried to beat that ever way we could. Every time we
