This is a preliminary transcript of Part II of the Gemini 4 (GT-4) flight crew debriefing, prepared by NASA's Spacecraft Operations Branch, Flight Crew Support Division, and dated June 18, 1965. The debriefing began aboard the recovery ship USS Wasp and ended at the Manned Spacecraft Center. In it, astronauts McDivitt and White discuss how the spacecraft systems performed, including the platform, OAMS, RCS and control modes. They also cover operational checks, visual sightings, experiments, mission planning and training, and give recommendations for future crews.

it was reading 56. Another hour or two after that
it had climbed slowly back up to 60 again. I
had a long time to look at it in the same position.
When we ended the cha.sing-around at the end of the
first hour, we were down to 70 percent indicated
and we never got below 50 percent in four days.
I'll tell you, the position it seemed to stay
for days and days was 59 to 60 percent. We fired
in Pulse Mode for a long time with the gage at
that position, and all of a sudden that one time
it dropped down to about 55 percent .
But then it came back up to 60.
I guess it did , didn ' t it? The temperatures all
stayed fairly constant. If I recall .right, they
dropped down to around 70 degrees. It seemed to
me they continually decreased throughout the
flight. I noticed this particularly in the RCS,
but I guess we'll get to that later. The propellart
quantity though , I think we mentioned earlier ,
ended up on our gaging at about 3 percent at the
end . We got a little bit of ground information on
the 0AMS propellant. I felt a little suspicious
of the gage when it kept staying there at 59 to 60
