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.

checked the Rate Command before we thrusted. It
did seem to be operating fine . Why don ' t you go
through the next part , Eli?
All right . We're going to get into the source
temperature and pressure , the regulated pressure ,
and the propellant quantity . Let ' s take the
temperature first . The temperature of our OAMS
was 75 degrees all the way down the line . The
i nit ial indications on the pressures were approxi
mately 2800 psi for the source and 320 psi for the
regulated pressure .
The quantity gage operated all right except that,
as I mentioned earlier , the thing seemed to wander
up and down somewhere between 2 and 4 percent ,
depending upon where you were in the mission .
You ' d read it one time and it would be 60, and
you'd read it a little while later and it would
be 62, and you 'd r ead it a little while l ater and
