Charles Donald Bateman, known as Don Bateman or C. Don Bateman, (born 8 March 1932, Saskatchewan, Canada) is the inventor of the Ground Proximity Warning System (GPWS), a device that is responsible for a marked decline in controlled flight into terrain accidents. It's accepted within the industry that Don Bateman has probably saved more lives than any single person in the history of aviation. — Bill Vos of the Flight Safety Foundation
