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.

Yes, I did most of mine with the clear one.
For the runs in the Air Force portion , I found
out that the stars had too big of an angle between
the star and the horizon. To actually follow
the format, for the runs as given , turned out
to be too difficult . We did make runs on stars
and horizons if we took the time on it and took
the measurements . It seemed like the angle was
fairly well limited between 20 and 25 degrees. This
was due to the limited maneuver capability impos ed
upon us and the lack of having enough window space .
If you get behind the sextant, behind the window, and
try to make a measurement, you might be able to
theoretically measure something out to 50 to 60
degrees . Theoretically , this may be possible, but
you must can ' t get yourself up above the console
circuit breaker panel or down into the foot well
area, which would be required to make measure
ments of this magnitude. There were definite
