Explanation:
First Public Display of a Hot-Air Balloon
The first public display of a hot-air balloon was conducted by the Montgolfier brothers, Joseph-Michel and Jacques-Étienne Montgolfier, in 1783. They launched their hot-air balloon, called the Montgolfière, on June 4, 1783, in Annonay, France. This event marked a significant milestone in the history of aviation, as it paved the way for the development of flight.
The Montgolfier brothers utilized the principles of buoyancy and hot air to create their balloon. The heat from a fire placed at the base of the balloon caused the air inside to become lighter than the cooler air outside, enabling the balloon to ascend. This demonstration captivated the public's imagination and led to further experiments in aeronautics.
Later that year, in September, they conducted another flight that carried a sheep, a duck, and a rooster for around 8 minutes and reached an altitude of about 3,000 feet. As a result of their pioneering work, the Montgolfier brothers are often credited with being the first to demonstrate human-controlled flight using hot air balloons.
