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.

as we came up into the Horizon Scanner Mode
dead.band , it started pulsing rapidly and
ki l led off this rather l arge pitch rate and held
the spacecraft right in this attitude . S~ we
had a very good acquisition of the mode from a
somewhat undesirable condi t ion . At the first
sunset the scanners were pointed right at the
sun but did not break lock. We did not get
any scanner ignore lights at this time . Later
on, at 17 : 04, about an hour later at sunrise ,
the scanner ignore l ight came on with the space
craft pointed in such a manner that the small end
of the spacecraft was pointed about 45 degrees
to the right of a line drawn directly between
the spacecraft and the sun. So tha t., essential ly,
the sun was shining on the horizon scanners at
about a 45- degrell angl e . The scanner ignore
lights stayed on for 10 or 15 seconds, and then
went out . There were no false pulses from the
jets at all . At 7: 55, just at sunse t , again in
about the same position, I was 45 degrees to the
