This prompted astronaut Gordon Cooper to propose and develop a mission patch for his and Pete Conrad's Gemini 5 flight: an embroidered cloth patch sporting the names of the two crew members, a covered wagon, and the slogan "8 Days or Bust" which referred to the expected mission duration. NASA administrator James E. Webb approved the design, but insisted on the removal of the slogan from the official version of the patch. The so-called Cooper patch was worn on the right breast of the astronauts' uniforms below their nameplates and opposite the NASA emblems worn on the left.
