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 My goodness, we had 30 per cent o2 l eft when we jettisoned
the adapter. 30 some per cent~ o2 and about 40 per cent
~ hydrogen. The OAMS were a l ittle di fferent situation.
We cut that off at about 2 per cent. I was a l ittle dis
turbed on the real-time f l ight planning in the l&et couple
of d.!cys when t hey were sending up for more experiments than
they knew we had f'uel to do . .And telling us to sift them
out. This sor t of puts the onus of not doing it on the
pilot. I guess in the l ong run i t is the best W8:3' to do it,
but they would call up and sa_y-, "well, here is a whole lot
of updates that you can do i.f you have t he f'uel." Well,
they knew darn well, we didn't have the f'ue l .
Lovell That is right.
Borman In ma.ny cases it turned out to be weathered a:nywa.y.
Lovell And we had been briefed that there was a rather large error
in the quantity- Nadout on the quantity gauge, and .fortun
ately .for us it l ooked like it was in our favor.
Borman We also had the Vol kswagon tank which helped out. So we
knew e:r:a.ctl y where we were then.
Lovell But we should, in future flights, make sure that the spa.oe
cra.ft has enough f'uel for adequate BEF alignment, and for
at least a coup l e of revolutions with enough reserve to m.a.ke
