The CPTP/WTS program was largely phased out in the summer of 1944, but not before 435,165 people, including hundreds of women and African-Americans, had been taught to fly. Notable legends trained under the CPTP include: Astronaut/Senator John Glenn, top Navy ace Alexander Vraciu, Douglas test pilot Robert Rahn, top World War II ace Major Richard Bong, triple ace Bud Anderson, former Senator George McGovern, WASP Dora Dougherty and Tuskegee airman Major Robert W. Deiz. The CPTP admirably achieved its primary mission, best expressed by the title of aviation historian Dominick Pisano's book, "To Fill the Skies with Pilots".
