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.

Lovell Yes.
Borman During the later part of it I started out in PULSE Mode and
:rolled over the 55 degrees in PULSE Mode, and. then when we
eot Guidance Initiate I went to DIRECT. I was finding that
in order to keep the cros11 range zeroed, and we had been
told that Wally had trouble with his cross range, I was
banking back and forth quite frequently maneuvering the
spacecraft around the full lift point, from one side to the
other and I was overshooting a little bit in DIRECT. I was
also starting to pick up some pitch and yaw oscillations, so
then I went to single ring RATE COMMAND. And boy, this was
really a great control mode, it "'8.S steady as a :rock. You
could put it right where you wanted and it st~ed there.
But pretty soon we eot dow a:round, I guess it was when the
g's were coming off, after 3.9 g•s. I started losing it in
