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).

Cooper
fine for two cartidges worth and then quit.
Was i t two or four?
I don't lmow, it was some l ow number. Maybe it was
four . Anyway, it quit fairly early in the flight .
The tape recorder was finished. DCS . Ok8iY , until
the last 30 minutes of the flight , the DCS couldn't
have been better. The updates were good , the
ground coordination was f ine on i t . The things
they gave us to put in the MDIU were given in a good
manner and were put in. No problem. Pete got
them all loaded in fine . No problem at all
until that last up-date we got from Carnarvon which
they updated us with our compu t er a~d reentry con
figuration, after we wer e all ready supposed to have
our last update from Houston and without telling
everybody to look on his board and see what mode
our computer was in, he sends this update which is
just about ... blew our cork there . And which I
think at this point right now, having experienced
this one occasion of this happening at the worst
possible time it could happen in, my recommendation
right now to flight crews is that they fly the DCS
circuit breaker in the OFF position.
I concur.FCSD Rep
