In 1783, thousands gather at the palace at Versailles to see the world's first hot-air balloon flight. The passengers in the basket? A duck, a sheep, and a rooster. All of this is historical fact.
After this introduction, Marjorie Priceman, in a nearly wordless section, goes on to imagine what that flight might have been like for the animals, had they been possessed of near-human intelligence and emotions, and a talent for pratfalls. They soar over France, getting tangled up in clotheslines, shot at by a boy with a bow and arrow, bumping into a church steeple, nearly falling out, getting flooded and attacked by birds, and finally crash-landing safely. It concludes with a brief timeline of the year leading up to the real event.
