Welcome to Hot Air Ballooning
A hot-air balloon is a light-to-air plane, containing an envelope, called an envelope, that contains hot air. The suspended bottom is a gondola or wicker basket (in some long-range or high-altitude balloons, a capsule), which is a source of passengers and heat, in most cases an open flame due to the burning of liquid propane.
The warm air inside the envelope makes it faster because it has a lower density than the cold air outside the envelope. With all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed downwards, because the air inside the envelope is under the same pressure as the surrounding air.
In modern sports balloons, the envelope is usually made of nylon fabric and the balloon inlet (closest to the burner flame) is made of fire-resistant material such as Nomex.
Modern balloons are made in all types of shapes, such as rocket ships and sizes of various commercial products, although traditional shapes are used for most non-commercial and many commercial, applications.
The hot air balloon is the first successful human-carrying flight technique. The first unethical manned hot air balloon flight was performed on 21 November 1783 by Jean-François Pilate de Roses and François Laurent D’Rellands in a balloon made by the Monteselfier brothers.
The first hot-air balloon in America was launched from the Walnut Street Jail in Philadelphia on January 9, 1793, by French aeronaut Jean Pierre Blanchard. Hot air balloons that can be circulated through the air instead of simply flowing with air are known as thermal airships.
