Wing walking is the act of moving along the wings of an aeroplane (most commonly a biplane) during flight, sometimes transferring between planes. It originated as a daredevil stunt in the aerial barnstorming shows of the 1920s, and became the subject of several Hollywood movies. An early exponent was Ormer Locklear, who was killed performing a dive on film. Charles Lindbergh began his aviation career as a wing walker.[citation needed]
