XRH1720005: 07/02/64 Multiple exposure of Rendezvous Docking Simulator. The Gemini spacecraft was supported in a gimbal system by an overhead crane and gantry arrangement which provided 6 degrees of freedom - roll, pitch, yaw, and translation in any direction - all controllable by the Astronaut in the spacecraft. The controls fed into a computer which in turn provided an input to the servos driving the spacecraft so that it responded to control motions in a manner which accurately simulated the Gemini spacecraft / Bridgeman Images
