Elm Farm Ollie

Elm Farm Ollie (known as "Nellie Jay" and post-flight as "Sky Queen") was the first cow to fly in an airplane, doing so on 18 February 1930, as part of the International Air Exposition in St. Louis, Missouri, United States. On the same trip, which covered 72 miles in a Ford Trimotor airplane from Bismarck, Missouri, to St. Louis, she also became the first cow milked in flight. This was done ostensibly to allow scientists to observe midair effects on animals, as well as for publicity purposes. A St. Louis newspaper trumpeted her mission as being "to blaze a trail for the transportation of livestock by air."
