During the early Gemini flights, the astronauts made some changes to the cockpit layout. One of the things they wanted was an extra GMT clock on the command pilot's side.

Just wondering, beside the known cockpit drawings, if we can see these changes in NASA cockpit photos (e.g. compared with S65-60604 below).

I have not been able to find views of the Command Pilot's panel of Gemini 3, but certainly by Gemini 4 the Bulova Accutron 24-hour clock was on the left panel.

The center panel originally included a flight plan scroll. (This can be seen on NASM photos of Gemini 4.) On Gemini 6 and up this was replaced with a numerical Ground Elapsed Time display, which you can see in that Gemini 7 photo between the two large rectangular gauges. (The Gemini 7 photo is in reverse).

Without getting into the story of astronaut instigation of requests for changes to spacecraft equipment and procedures, here are some images of the "Gusmobile" instrument panels.

This image S65-13920 taken on the 25th January 1965 shows backup crew, Wally and Tom in the Gemini simulator prior to the mission. Simulators don't always reflect the actual equipment layout, although I believe that the simulator was at "flight" standard by the time of this photo. Even so, the lack of an Accutron clock (blank gray panel secured by 4 screws immediately left of ADI) does not necessarily mean the actual spacecraft was not fitted with one although the Gemini Familiarization Manual seems to indicate that it was not.

This is supposedly a "closeout" image of GT-4 - GT4 KSC-65C-3501 02 June, 1965, the day before launch - and the flight plan scroll mentioned by "space1" had not yet been fitted although the clock has been.

However, although hard to see, this National Air and Space Museum image of Gemini IV (Image No. 24) — from NASM GIV Images - shows that the clock is no longer fitted. Maybe it was sourced for later missions.

All times are CT (US)
