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 didn't think you noticed it earlier when we
were working.
Well, I did notice it a little bit in that first
orbit, but it wasn't distracting at all. It would
just drift off a little bit and I'd whop it and
it would be back . At SEX:;0 + 30, I used the trans
lation thrusters to damp the booster-spacecraft
rates . One of them was a little higher than the
other, although they were both down in the order
of a half of a degree/second. I did fire one
thruster one time or possibly two times to damp
the rate. I don't know if it was pitch or yaw .
You know, you are working in spacecraft pitch and
booster yaw and spacecraft yaw and booster pitch.
I was getting my coordinate system transformed
around in my mind, going from booster coordinate
system to the spacecraft . I don't remember
whether it was yaw or pitch, but I did thrust
once or twice. By the way , I could hear those
thrusters fire. At SEC0 + 30 I said, "Thrusting, "
and I started thrusting. "Separate" , and Fd
punched the SPACE.CRAFT SEPARATE. We were in Direct
and I thrusted straight ahead for about 5 seconds.
Then I went back into Rate Command. Separati on was
