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.

arc was that this thing cut out. That thing
was a real lifting body. You ' re really getting
a lot of lift initiall y, and if you roll around
there, you ' d kill it all off; and your aero
dynamics is such that you really can't tell,
because the stability is so loose right there .
White You know you're going to get some lift if you
have an offset CG, but you couldn't tell
where it was going ,
McDivitt You ' re in the area where you're getting a lot of
lift so i f you do a roll , you've lost that
range right off the bat . We came down on this
great big spiral, and here I think we ought to
get into
6.4 Acceleration Profile
McDivitt - - the acceleration at retrofire. I called
down on the ground and told them that we had
four retros . We got automatic. We got auto
retro . We got all four in sequence . We got
auto- retro . Auto- retrofire appeared to be about
a second and a half early . In the acceleration
profile I said, "Well, here come the g ' s, Ed . "
and I felt the g ' s going up. He said yes.
