On February 18, 1930, a Guernsey cow from Bismarck, Missouri named Elm Farm Ollie1 became the first cow in history to fly in an airplane as part of the International Air Exposition in St. Louis, Missouri. The trip covered 72 miles, with Ollie taking off from Bismarck, Missouri, and landing in St. Louis, Missouri. During the flight she was milked, also making her the first cow ever milked in the air.
She produced 24 quarts of milk during the flight, which was sealed into paper cartons and parachuted to spectators below. Charles Lindbergh reportedly received a glass of Ollie’s milk.
