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.

which was Hawaii , I asked them how we were
doing on electrical power . They sai d that we
were 160 amp- hours ahead of the curve . We had
a 200 amp- hour cushion, so that meant that we
had a 360 amp-hour pad on our flight pl an. In
the meantime , I had checked to see what the
computer- ON , IGS Power Supply-ON took . It
took 5. 6 amp-hours to power this thing. We
were at 76 hours on a 96- hour mission and we
had about 20 hours to go . Twenty times 5. 6 is
