This is a preliminary Part II transcript of the Gemini 5 (GT-5) flight crew debriefing, prepared by the Spacecraft Operations Branch of NASA's Flight Crew Support Division and dated September 2, 1965. 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. NASA conducted this debriefing between August 30, 1965, and September 2, 1965, at the Crew Quarters, Cape Kennedy, Florida. Astronauts L. Gordon Cooper and Charles “Pete” Conrad described observing debris and “snow” and “all sorts of glittering pieces of this, that and the other thing” in the “Visual Sightings” section of the document (pages 157-220).

Concerning mission planning. I would avoid wiring ,:.
experiments such as MSC-1 . They clo·:iber up very
critical time phasing in the mission. For instance,
arming the Bus Arm Switch at SECO added an unneces
sary step at an extremely time-cri ti,::al time, which
is just pure lousy engineering pl anning. That door
could have been blown by any number ,)f circuits.
It didn't have to put i t on that one.
The next thing is the laying out of t he flight plan .
It became obvious that we were crowd,3d , So , I think
they should take a more objective l ook at these
quential aspects of f light planning, particularly
in terms of how long it takes t o complete one ex
periment. This business of being pitched all the
way to the nadir, going backward, th,m having to
pitch forward again to pick up t he next target , is
time consuming. Neither the flight plan peop l e,
the crew, nor anybody el se for that rnatter picked
this up until we were flying .
Sleep cycl es, On the long flights you have to plan
for dual s l eep cycl es. Stations shoul d monitor and
not transmit . The crew shoul d sleep at the same
