According to Official Guinness Records,
Frenchman François Pilâtre de Rozier is widely regarded as the first person ever to have flown. On 15 October 1783 he rose 26 m (84 ft) into the air in a tethered hot air balloon built by the inventors Joseph and Jacques Montgolfier (France).
On 21 November he and the Marquis d'Arlandes became the first humans to make a free manned flight when they took off from the Bois de Boulogne, Paris, and made a 25 minute flight.
