Elm Farm Ollie was a Holstein cow who gained fame for being the first cow to fly in a fixed-wing aircraft. The flight took place as part of a promotional effort to demonstrate the potential of aviation in agriculture and dairy farming. Organized by the North Dakota Agricultural College, the flight took off from Bismarck, North Dakota, and headed to St. Louis, Missouri, as part of the National Dairy Show. The aircraft, a Ford Trimotor, was specially modified to accommodate the cow, who was brought aboard alongside her caretaker. One of the most notable aspects of this event was that Ollie was not only a passenger but also became the first cow to be milked mid-air, showcasing creativity and the practical applications of aviation in agriculture.

The event captured the imagination of the public and the media, blending agriculture with advancements in flight technology. It highlighted the optimism of the early 20th century, where innovations in technology were increasingly being applied across various fields, including farming. Elm Farm Ollie's airborne adventure was widely publicized, and photographs of her time in the sky captivated audiences, making her a symbol of this unique intersection of agriculture and aviation. This initiative aimed to bolster the public perception of the dairy industry and encourage the use of aeronautics in rural settings.

The success of Elm Farm Ollie's flight paved the way for further demonstrations of the capabilities of agricultural aviation tools. Following this event, the idea of using planes for transporting livestock and dairy products gained momentum, influencing future practices in both farming and aviation logistics. It represented a pivotal moment in recognizing how technology could assist traditional farming methods, ultimately contributing to the modernization of the agricultural sector.
