The hot air balloon is the first successful human-carrying flight technology. It was today in 1783 that manned hot air balloon flight was performed by Jean-François Pilâtre de Rozier and François Laurent d’Arlandes in Paris, France. The flight lasted 10 minutes.
A hot air balloon is a lighter than air aircraft consisting of a bag called the envelope that is capable of containing heated air. Suspended beneath is a gondola or wicker basket, which carries passengers and a source of heat, in most cases an open flame. The heated air inside the envelope makes it buoyant since it has a lower density than the relatively cold air outside the envelope.
