It records astronauts Cooper and Conrad at the Crew Quarters, Cape Kennedy. They discuss how the spacecraft systems worked, including the platform and the OAMS thruster failures. The transcript also covers operational checks, visual sightings, experiments, training, premission planning, and medical aspects. It was originally classified Confidential.

From the source:Release of 2026-06-12 Incident: August 30 - September 2, 1965, Cape Kennedy, Florida. This document is a preliminary transcript (Part II) derived from voice recordings of the Gemini 5 flight crew technical debriefing.

•
We had some thrust remaining in every axis but yaw
l eft . We had some in yaw left if you just wanted
to dump raw fuel overboard . I don ' t know whether
it was fuel or oxidizer.
Cooper Generally, what we'd do is roll and pitch to get
our yaw left .
Conrad I f we were tumbling and wanted to damp we just
waited until we translated into the right axis in
whi ch we had some authority .
Cooper The one axis that always seemed to work pretty good
so far as control authority was pitch.
Conrad Yes
Cooper Pitch up and pitch down seemed to work reasonably
well all the time.
Conrad Yes . I wonder i f that had something to do with the
pitch thruster lines on the manifold being close
to the source. Pitch was always good . Our trouble
was mainly coupling in the yaw thrusters both right
and left.
Cooper Source pressure was easy to monitor . SJurce temper
ature we could monitor and it was too CJld .
