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.

At that time I realized that we were going to feel the pyros and stuf'f--feel the separation. It was a very distinct feeling when we sepa r ated . Of course, we immediately dropped in the thrust . There wasn't any question,we had a good separation, in my mind . This is just the way it was for all of our separations. Ev-erytime we separated, it was very clear that was what had happened. Oh, yes, there wasn't a:ny doubt about it when that first stage shut off--Voom! Staging was just as it should have been. Engine 2 started right on up. Like I mentioned earlier~the light went out and the tank pressure went down just a tad, but it stayed way up there, about two or three times as high as was necessary for staging. It never really did decrease. It stayed up around 45 or 50 psi, and we need 20 for staging, so-- I couldn ' t hear anything. Didn't you hear the engine? No. I was listening but it still was quiet. €Ot~FIDENllAL --
