Hot air balloons are the oldest successful human flight technology, dating back to the Montgolfier brothers' invention in Annonay, France in 1783.
The first flight carrying humans was made on November 21, 1783, in Paris by Pilâtre de Rozier and the Marquis d'Arlandes.
The first clearly recorded instances of balloons capable of carrying passengers used hot air to obtain buoyancy and were built by the brothers Josef and Etienne Montgolfier in Annonay, France.
