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.

30 in another , and 30 in another. I never really
ea..11e to a posi tio:1. to try to ni1ll all these
things out to see what the total 6V was. I
was putting in the thrust with mostly the aft
thrusters and the down-firing top thruster.
I don't think I used the left and right thruster,
at all. I don 1 t think I used the bottom
thurster at all. There was no difficulty
controlling a~y of them. I used the forward
firing thrusters once or twice to try to slow
dow:i, to take out total velocity.
Then there was the Accelero~eter Bias Check
lwhich was another one of those things. I don't
know hon I let it get into the flight plan .
We both joked about that one , huh , Mac? We
were really going to get an Accelerometer
Check when we were trying to track the booster.
I was putting 1 6V ' s on the IVI 1 s at a rate of a
foot per minute at least. We ended up with over
a foot per minute, I think , over that period
of time. We couldn I t have checked anybody 1
s
accelerometer bias, so I just didn't even fool
around with it . We were supposed- to take a
blood pressure. Did you take that blood
