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.

so that when you go across it, you not only lmow
the general area thRt you're supposed to point into,
but the exact spot where that target is and
some identifying f eatures that wil l lead you
to this target. So with the initial things
like a lot of contrast to get you in the area
and then a lot of detail gathered either from
target study or from a previous pass across the
target,I think that you could go ahead and
find it . Once on the target the tracking
task in the Pulse Mode is not difficult at all .
I think you can track within just tenths of
degree s of the target without too much difficulty
whatsoever, in multiple axes . And I found that
without having the platform up every.,
tracking task I did was in multiple axes , and
although you're going through some very
peculiar maneuvers, it ' s very instinctive to
track up and down, left and right, using the
gunsight,without any regard to what your attitude
with respect to the local horizontal is. In
air- to-ground gunnery you sometimes find that
you ' ve got to pick your attitudes up from the
