Note: Charles Townsend Ludington, Sr. (1896-1968) was known as a pioneer in the world of aviation. Throughout his career, he helped found and run several American airlines, planned and designed airports, created designs for airplanes, gliders, and protection devices for pilots, and authored a textbook on aerodynamics. Several of the books offered here are from his personal collection and were passed down to his descendants.
