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.

180 McDivitt McDivitt Sunrise seemed to be the time at which t he scanner had the largest tendency to br eak lock , and if it didn ' t break lock, it would at l east put in spuri ous inputs which were obviously not required other than due to the confusion factor that the sunrise was causing on the scanner. Again, I have one at 11 : 58 , at sunrise , the scanner 60 degrees to the sun , broke lock once and pul sed quite a few t imes extr aneously , but caught itself and continued to track . I think on the whole that the scanner worked real well . So do I . As a matter of fact , I bel ieve in the last 20 or 24 hours, however long we had the Horizon Scan Mode on , that we only real l y lost control of the spacecraft that one time, where we did the pitching maneuver I've already discussed . I think in every other instance , although it pulsed needlessly two or three times at sunset if the scanner was pointed toward the sun, it never really lost lock and it certainly never l ost control . The light would come on every now and then , but it would --. But , I don ' t thi nk that the light came on more than three or four times in t hose l as t 24 hours . C8NFtDE~~TIAl
