Roy Kimbell, 85, who served as a B-29 super fortress mechanic during the Korean War, went on to graduate from the South Dakota School of Mines with a masters in mechanical engineering before working for 30 years as a jet engine performance engineer for aerospace manufacturer Pratt & Whitney. While his career was based in the testing of jet engines, “this is my first love” Kimbell said in reference to the propeller plane he was working on. “Since I’m retired this is sort of a fun thing to do.”
