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.

McDivitt That's right. It's very comfortable . Steady on-
set .
White Not very long. Gee, we were below--

staging, from about 2:15 on to 2:30 . I could
feel pogo.
White How much were you getting?
McDivitt Very little, I could just feel it pull like this.
Did you feel it at all?
