Titan I engine

I photographed this Aerojet General LR91-AJ-3 engine at the South Dakota Air Museum. These were used to propel the second stage of the Titan I ICBM to a speed of Mach 15. The Titan engine was instrumental in the flight of the Gemini space missions, including the first space walk and first docking of space craft.
