Wing walking has in fact existed since the very early days of aviation, and originally referred to the actions of daredevil aviators when they moved about on the wings of aircraft during flight. One of the world’s first wing walkers was US lieutenant Ormer Locklear (born 1891), who, during his pilot training in World War I, just climbed out of the cockpit onto the wings in flight whenever there was a mechanical problem and fixed it! Locklear died in 1920 while performing a wing walking stunt for a film. However wing walking remained a popular performance during air displays throughout the 1920s, which were often referred to as barnstorming shows.
