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.

We were getting aerodynamic noise, which built up
to max q . We got some pretty good vibrations at
max q .
That's where I had the most vibrations . It was
just shaking like this .
It was vibrating and noisy.
That was the loudest noise we received the whole
flight.
Right after max q it got very qui et .
This is where I had the most vibrations . There
were more than I expected.
Yes, me too. You can ' t simulate this in a simula
tor . You get more vibrations than you do noise .
The only thing they have in the simulator is
noise, they don't have vibrations . It was pretty
loud and the spacecraft was actually shaking
around a lot. It was really vibrating.
Yes, it was . More than I expected .
The whole thing was really going at it . Almost
like a F-80 or a T-33 at a.bout 0.8 Mach.
Very good analogy.
