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.

just can't simul ate t his . When I looked down
at the ball and did t he retrofire, i t was just
l ike the simulator. When I was l ooking outside
and actually seeing what the spacecraft was do
ing as I cont rol led i t , it seemed like it was
a lot sloppier with the RCS than it was wi th
the OAMS .
We must have fired over New Mexico or Texas .
Our retrofire?
Yes . I could see the old brown sandy earth
down right under us .
Yes , Guaymas gave us our countdown , so we were
over northern Mexico .
That ' s the area that I thought we were over .

west Texas.

to our retro attitude. We reported our TR- 5
Checklist complete . I don ' t know exactly when
Guaymas came on the radio .
