Take a look at this film. Fabulous footage, although grainy due to time and
bad equipment in those days compared to today, but what nerve this gal had.
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 classic barnstorming fashion to save an airplane that has
lost one of its main wheels.
Ingles is flown up with a replacement wheel strapped to her back and then
off she transfers herself from the rescue plane to the one missing the main
landing 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.
She died at 82 in the 1980's.
