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.

the flight, and I think about it right now. And
I thought about it during the flight. I think it's
time to start a crusade. I think it's time to
start a crusade on the elapsed time. Get us a
clock. It's going to cost money, but I think we
ought to get ourselves a good elapsed time clock
inside the spacecraft. Get FOD to start going on
elapsed time. And here's another funny sounding
one, but I don ' t see why we couldn ' t do it--why
we couldn't have a flight watch in ten-hour in
crements. Let somebody build a ten-hour watch
with a counter on ten hour increments . And then
we'd have the timing system that we need on the
spacecraft. What do you think of that? I know
you and I have talked about this before but I
think it's time--
Yes. We were forced to run our mission using
both elapsed time and Greenwich Mean Time and it's
almost an insurmountable problem.
I think it's really got our data all fouled up
right now , too . I think we'll unsnarl it all
right, but, boy, if we could've been putting
all our times into those tapes and on our data
books in str~ight elapsed-time increments, and even
