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.
From the source:Release of 2026-06-12 Incident: 6/9/65, North Atlantic Ocean. This document is a preliminary transcript (Part II) derived from voice recordings of the Gemini 4 flight crew debriefing taken aboard the recovery ship, USS Wasp, on June 9, 1965. Part II of this document contains the “Visual Sightings” section of the debriefing (pages 196-224), where astronauts James McDivitt and Edward White describe their observations while aboard the spacecraft.
McDivitt White never had to come off it again . We didn ' t get any abnormal operation of the radiator at any time . One time they called up to me and mentioned some thing about the radiator and the coolant loop and I didn ' t get any clarification . I lost contact at that time , and I thought just maybe that I had a failure of some type in my primary cooling system . So just for caution sake I turned on the secondary coolant pump and waited till I got con tact with them again. They asked me why I had the secondary pump on, and I said , "I thought maybe I had a problem in the primary system ." They asked me why I thought that and I said , "I thought they were telling me something about it when I lost contact with them. I did it just to be sure ." But that was the only time that I thought we even might have had a problem in it , and I turned it off . We used double coolant loop early in the mission,and after we turned the secondary system off we did not use it a.gain until the teentry. Prior to the reentry , we turned it on . That's right . That coolant system real ly worked. Okay , here is one at which we'll get at them--
