This is a preliminary transcript of Part I of the Gemini 4 (GT-4) flight crew debriefing. The Spacecraft Operations Branch of NASA's Flight Crew Support Division prepared it on June 16, 1965, from recordings of the debriefing held aboard the USS Wasp on June 9, 1965. In it, astronauts McDivitt and White describe the mission from an operational viewpoint, covering countdown, powered flight, insertion, orbital operations, reentry, landing and recovery. According to the preface, visual sightings were left for a later part.

the RCS heater troubles and we had them coming on
for the next three to four hours. We had them
cycled on and I called the times down. I don ' t
believe we want to go over them all right now . I
had them cycled on and off at intervals of about
15 minutes, for a total of eight different times .
They started coming on exactly at 06 :47 and the
last one I had was on at 08:23. That was the
last time we had any RCS heaters. It was rather
peculiar because they alternated. First the
A-Ring would come on and the B- Ring would come on
and the A-Ring would come on, and so on.
Is that right?
They came on at approximately 15-minute intervals
and it took approximately five minutes to bring
the temperature down to within limits. I reported
those down and they seemed to be interested in
getting exact on/off times of our heaters to plot
our electrical profile curve. I ran an Apollo
Landmark Run Noo 6 with yaw 15 and pitch 30 . I
think the results of that are in the other log
book. I reported down at this time that ~im had
a successful bowel movement . I already had one .
