Balloon flight

In 1783, Jean Francois Pilatre de Rozier, a professor of physics and chemistry, and the Marquis Francois Laurant d'Arlandes became the first men to make a free flight. Their hot-air balloon lifted off from La Muettte, a royal palace in the Bois de Boulogne, Paris. They flew nearly 6 miles in 25 mins, reaching an altitude, it is thought, of around 3000-ft (though this is poorly documented). Spectators included Ben Franklin and King Louis XVI, who offered to send two prisoners, but Rozier wanted to deny criminals the glory of being the first men to go into the atmosphere. The Montgolfier brothers, Étienne and Joseph, had publicly demonstrated the first unmanned hot-air balloon a few months earlier, 5 Jun 1783, and a second with animals on 19 Sep 1783 to verify that air travel was safe for live beings. Pilatre began with low, tethered flights on 15-19 Oct 1784. After Pilatre, gas balloons were favoured.«
