The hot air balloon is the oldest successful human-carrying flight technology. The first untethered manned hot air balloon flight was performed by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes on November 21, 1783, in Paris, France,^[1] in a balloon created by the Montgolfier brothers.^[2] Hot air balloons that can be propelled through the air rather than simply drifting with the wind are known as thermal airships.
