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.

three times the detail of the section cut out of a
Mercator Chart , which I found very useful . By prop
erly folding a map , I think I would prefer to have a
map of even higher detail with me. It didn't seem to
me to be a drawback to have a large map in the cockpit,
as long as you kept it gelded down in the proper
manner. Do you have any comments on that?
Well , I agree with lli . I thought that this was a
relatively simple task. I felt it would have been
much easier to do if we had the platform up so we
could point the spacecraft down using inertial ref
erence and using the platform, but it wasn't diffi
cult to do it just visually. It only took a short
time to plot up a couple of points and run back and
determine your own ascending node .
You kn.ow, another thing that I found very interesting
was when they called up plot points and they' d give
you 30 degrees right , down 45 degrees . Even without
the platform, those meant a lot to me . I could
visualize very easily where I was going, whether I
was small- end-forward or blunt end forward. I could
visualize quite well, without a platform , 30 degrees
down and yaw 30 degrees over, looking for a point .
It seemed I could check points nearly as well wi th
