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.

--,
I ' m not sure.
The caging of the thing with small- end-forward in
the daytime was r elatively easy . At night I don't
think it would be quite tha t simple . I think what
you would have to do at night time is to point
the spacecraft down at the ground pretty much so
you can see the track ac ross the ground, I could
see which way the land was moving under me . I
felt--although I never did this--that if I could
do that and then roll around to where I had no
bank angl e , and fac e in my yaw direction, either
small-end or blunt-end- forward , stop t he ro l l t her e
and pitch up to the horizon I could cage there
withi n plus or minus 10 degrees for sure . It was
much less accurate at night, I felt, than in the
daytime .
You aren' t kidding! We both felt that on those
dark nights when you really couldn ' t see anything
on the ground, pure star reference for yaw was
pretty rough .
Pure star reference for yaw was almost impossible
to use. That was the only place where that thing
we decided not to take with us--the view of the
stars through the window--might have been of some

Cases discussed
