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.

we switched to DIRECT and in DIRECT we did not e;et. a.ny
ignition at all as far as I could tell . In t he OAHS PULSE
yaw righ c, we were getting slight little pops . It seemed
we had about { control authority that we had before we
experience~ the probl em. We went to DIRECT, to see what
effect DIREC11 ha<l on it and we got some thrust, but i t was
a. '1•hishing. We weren't getting any sound of the
thrusters. It was a whishing sound . T think we were only
getting an impulse either from the oxi<lizer or the fuel
escaping.
Lovell We couJd hear a cJicking of the solenoids or the operation
of the va l ves, whatever they were back there . They were
worki ng all r ight, but we were not eetting any resuJtant
thrust.
Borman Right. Systems Monitoring : Source pressure was fine .
Went right down the predicted sche<lule .
Lovell As a mRtter of fact, the s ource pressure dropped, just a r
pre<licted , when we ran out of initial 0.Al18 fuel before we
went to the re serve tank. Tt came back in at;air. when we
actuated the squib.
Ilorman ?To , that wasn't the source pressure, that was the regul ated
pressure.
Lovel l I mean the regulated pressure, I'm sorry.
Borman The source temper ature worked fine throughout the flight. Official release, from the pursue collection. The PDF is mirrored here; the original link is above. 222 pages are in the text index: search them above, or from the library's search.
