The hot air balloon is the oldest form of flying technology that can successfully carry people. The earliest use of hot air to make objects fly was made in Ancient China. Paper lanterns were sent into the air for signalling.
The first hot air balloon to carry a person was made by the Montgolfier brothers. On 19 September 1783, they demonstrated their invention for King Louis XVI and Queen Marie Antoinette at the French court in Paris. The passengers were a sheep, a duck and a rooster. They flew for 480 metres. The first flight carrying a person was on 15 October 1783. It carried Jacques-Etienne Montgolfier. The balloon was attached to the ground by a rope. The first free flight, without being attached to the ground, was a few weeks later, on 21 November 1783. It carried Marquis François d’Arlandes and Pilatre de Rozier.
