A sheep, a duck, and a rooster were the first passengers on a hot air balloon.
On September 19, 1783 a hot air balloon took off from Versailles carrying this strange assortment of animals. The flight lasted a total of 8 minutes and was witnessed by Louis XVI, Marie Antoinette, and the rest of the French royal court of the time. I have no idea why these specific animals were chosen, but they were surely attempting to ascertain whether this mode of transportation would be safe for human passengers. Just one month later, Pilatre de Rozier and Marquis d\'Arlandes became the first human hot air balloon passengers in history!
