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.

of goes along with putting the following
missions in front of the mission that ' s about
r eady to go . One last comment that I would
like to make on the simulator is that we made
a mistake in building it so that it t-JOuld only
tilt up 30 degrees . This lying on your back
in a simulator is for the birds. You can sit
up in it a lot longer than you can lie on your
back . Also, everything that you have to do
when you're lying on your back is about five
times harder than it is when you're sitting up-
nothing at all like zerc g. I feel strongly
that we should look into some method of making
this simulator go all the way up to a 90-degree
point .
White Here , here! One other thing on this simulator ,
too , whil e we're thinking about it . I think ,
there 's no question in my mind, the most effective
trainer we have is our mission simulator. I
think it could be made about a third more
effective if we had a decent out- the-window
horizon provided . We didn' t have anything that
I ' d call satisfactory available to us prior to
