Interesting data

NASA and USAF were initially required to have a joint control of the program, but later the supervision was handed solely to NASA.

Gemini was the first American space mission to have an onboard computer.

A member of Mercury-7 group, astronaut Gus Grissom was heavily involved in the Gemini program.

All but one Gemini vehicle (Gemini 1 was destroyed) are exhibited in various venues in the US – including US Air Force museum and NASA museum.
