This is a preliminary transcript of Part II of the Gemini 4 (GT-4) flight crew debriefing, prepared by NASA's Spacecraft Operations Branch, Flight Crew Support Division, and dated June 18, 1965. The debriefing began aboard the recovery ship USS Wasp and ended at the Manned Spacecraft Center. In it, astronauts McDivitt and White discuss how the spacecraft systems performed, including the platform, OAMS, RCS and control modes. They also cover operational checks, visual sightings, experiments, mission planning and training, and give recommendations for future crews.

From the source:Release of 2026-06-12 Incident: 6/9/65, North Atlantic Ocean. This document is a preliminary transcript (Part II) derived from voice recordings of the Gemini 4 flight crew debriefing taken aboard the recovery ship, USS Wasp, on June 9, 1965. Part II of this document contains the “Visual Sightings” section of the debriefing (pages 196-224), where astronauts James McDivitt and Edward White describe their observations while aboard the spacecraft.

reading the way I wanted it. Ha, ha! The
squib batteries--our electrical briefing I
thought, · wa.s very good. Everything behaved just
the way they told me . The squib batteries star ted
out pretty high, around 27 or 28 volts , and they
progressively decreased in voltage as we went
through the mission . The main batteries--every
time I checked them they always checked out at
about 9 • as far as the amps were concerned . The
adapter batteries--I was glad we'd had the brief
ing on them because I realized that knees on the
adapter batteries were in operation during the
launch when we got a high reading on the left
stack ammeter up around 27 or 28 amps, and we had
a reading of around,I believe,14 amps on the right
one. I didn't alarm Jim with this information
because it was still below my cut-off point of about
30 amps or so. I felt that it was due to the knees
in the adapter batteries causing unequal loadings
of the main batteries with respect to the adapter
batteries.
Hold it . I want to make some comments about the
electrical system and the power as we used it .
