Vaughan was instrumental in the creation of products such as the Wright Whirlwind J-6 plane, used by Charles Lindbergh, and the Wright Cyclone engine series, which were used in DC-1 aircraft. Vaughan’s real achievements, however, came during World War II, when he expanded production from 4 plants to 17, producing almost 150,000 engines and propellers each, and over 25,000 aircraft. By the end of his term, sales had grown to $128 million in 1949 from a level of $11 million in 1933.
