This is a preliminary transcript of Part I of the Gemini 4 (GT-4) flight crew debriefing. The Spacecraft Operations Branch of NASA's Flight Crew Support Division prepared it on June 16, 1965, from recordings of the debriefing held aboard the USS Wasp on June 9, 1965. In it, astronauts McDivitt and White describe the mission from an operational viewpoint, covering countdown, powered flight, insertion, orbital operations, reentry, landing and recovery. According to the preface, visual sightings were left for a later part.

Finally around this 66 hours, we'd dumped the thing down to 880 psi on the gage. This was why we didn't have to dump it so often. We'd been dumping it before around 960 psi--dump it there and bring it back to around 930 psi and let it build up, and then repeat the cycle again. That was about every 4 hours. Yes . We had to dump at least every 4 hours . We brought it dovm to 880 psi and this gave us a period of around 12 hours. You know, I thought this was a very clever method of holding the cabin at a higher pressure than normal by McDonnell--putting the vent down so low that it vented in a normal mode. You ~itw:rb\ l
