The Great Waldo Pepper is a 1975 American drama film directed, produced, and co-written by George Roy Hill. Set during 1926–1931, the film stars Robert Redford as a disaffected World War I veteran pilot who missed the opportunity to fly in combat, and examines his sense of postwar dislocation in 1920s America. The cast includes Margot Kidder, Bo Svenson, Edward Herrmann and Susan Sarandon. The Great Waldo Pepper depicts barnstorming during the 1920s and the accidents that led to aviation regulations by the Air Commerce Act. Plot 1926: World War I veteran Waldo Pepper feels he has missed out on the glory of aerial combat after being made a flight instructor. After the war, Waldo had taken up barnstorming to make a living. He soon tangles with rival barnstormer (and fellow war veteran) Axel Olsson. Antagonistic at first, Waldo and Axel become partners and try out various stunts. One of these stunts, a car-to-aircraft transfer, goes wrong and Waldo is nearly killed after Axel is unable to climb high enough to clear a barn, slamming Waldo into it.

But while performing this new stunt for the first time, Mary Beth freezes up on the wing, afraid to return to the cockpit. As Waldo (who did a "plane-to-plane transfer" in flight to
