Amazing Hot Air Balloons Of The World

The hot air balloon is the oldest successful human-carrying flight technology. It is in a class of aircraft known as balloon aircraft. On Nov 21, 1783, in Paris, France, the first untethered manned flight was made by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes in a hot air balloon created on Dec 14, 1782 by the Montgolfier brothers. Hot air balloons that can be propelled through the air rather than just being pushed along by the wind are known as airships or, more specifically, thermal airships.

At the very start, the first balloonists burnt materials onboard the balloon to generate heat to propel the envelope into the air. This theory then became obsolete as gas and helium designs were introduced as it was considered safer and more reliable than flying with an open flame. It is only within the last 50 or so years that hot air balloons have come back into interest.
