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.

the flight plan. They e;a.ve us one minute and 16 or 17 sec
onds, &nd the flight plan called for 46, I think.
Borman Well, we may get that cleared up when we talk to the ground.
But, it was greater than I thought we had planned to do.
Updating throughout the flight was excellent. Checklist
wa.s fine and, of course, we did not use the computer.
Lovell We might mention here that both Frank and I think making
adjust maneuvers without a platform is very feasible. You
can use the reticle for alignment and use the stars a.s a
reference. Since you a.re usu.a.lly using the aft thrusters,
you do not have thruster light to worry about. You can
turn down the lights. It takes two people thoughf one per
son to burn, hold attitude on the star, and watch the star
reference and the other person to time. It required two
people, but it is & very feasible method of doing it. I
think you get some very good accuraciea with it, because we
found out from the second burn.
8.3 RCS
Borman RCS operational checks were nominal. We had no problems at
all with the RCS. System monitoring was perfect and it did
not drop one bit during the 14 da.ys. After we actuated it,
it vent from 3,000 to about 2,600 to 2,500 psi on the source
pressure. No problems. Control mode-s, RATE COMMAND. .AJJ I
