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.
7 White McDivitt White it was reading 56. Another hour or two after that it had climbed slowly back up to 60 again. I had a long time to look at it in the same position. When we ended the cha.sing-around at the end of the first hour, we were down to 70 percent indicated and we never got below 50 percent in four days. I'll tell you, the position it seemed to stay for days and days was 59 to 60 percent. We fired in Pulse Mode for a long time with the gage at that position, and all of a sudden that one time it dropped down to about 55 percent . But then it came back up to 60. I guess it did , didn ' t it? The temperatures all stayed fairly constant. If I recall .right, they dropped down to around 70 degrees. It seemed to me they continually decreased throughout the flight. I noticed this particularly in the RCS, but I guess we'll get to that later. The propellart quantity though , I think we mentioned earlier , ended up on our gaging at about 3 percent at the end . We got a little bit of ground information on the 0AMS propellant. I felt a little suspicious of the gage when it kept staying there at 59 to 60
