Gladys Ingles was a member of a barnstorming troupe called the 13 Black Cats in the 1920s. Ingles was a wing walker; in this film, she shows her fearlessness in a classic barnstorming fashion to save an airplane that has lost one of its main wheels. Ingles is shown with a replacement wheel being strapped to her back and then off she goes as "Up She Goes," a duet from the era, provides the soundtrack. In the video, Ingles transfers herself from the rescue plane to the one sans main gear tire. She then expertly works herself down to the undercarriage only a few feet from a spinning prop. It's certainly a feat many mechanics 

wouldn't even try on the ground with the engine running.
