Montgolfier Brothers Launch First Public Hot Air Balloon
In the years leading up to the French Revolution, inventors Joseph-Michel and Jacques-Étienne Montgolfier experimented with lighter-than-air flight in their hometown of Annonay, France. Building on observations of smoke rising, they constructed a large linen envelope treated with paper and designed to trap hot air. On June 4, 1783, they staged a public demonstration before a crowd of officials and onlookers, releasing an unmanned balloon that rose approximately 1,000 meters and traveled about two kilometers. The successful flight lasted roughly 10 minutes before the balloon descended safely. This event marked the first documented public ascent of a hot-air balloon and sparked widespread interest in aeronautics across Europe.
