In Paris, Jean-François Pilâtre de Rozier and François Laurent d'Arlandes, make the first untethered hot air balloon flight.
Franois Laurent d'Arlandes (French pronunciation: [fswa lo l vj dald]; 1742 1 May 1809) was a French marquis, soldier and a pioneer of hot air ballooning. He and Jean-Franois Piltre de Rozier made the first manned free balloon flight on 21 November 1783, in a Montgolfier balloon.
D'Arlandes was born in Anneyron in the Dauphin. He met Joseph Montgolfier at the Jesuit college of Tournon. He became an infantry officer in the French royal guard.
The first public demonstration of a balloon by the Montgolfier brothers took place in June 1783, and was followed by an untethered flight of a sheep, a cockerel and a duck from the front courtyard of the Palace of Versailles on 19 September. The French King Louis XVI decided that the first manned flight would contain two condemned criminals, but de Rozier enlisted the help of the Duchess de Polignac to support his view that the honour of becoming first balloonists should belong to someone of higher status, and d'Arlandes agreed to accompany him. The King was persuaded to permit d'Arlandes and de Rozier to become the first pilots.
After several tethered tests to gain some experience of controlling the balloon, de Rozier and d'Arlandes made their first untethered flight in a Montgolfier hot air balloon on 21 November 1783, taking off at 1:54 p.m. from the garden of the Chteau de la Muette in the Bois de Boulogne, in the presence of the King. Also watching was U.S. envoy, Benjamin Franklin. Their 25-minute flight travelled slowly about 5 miles (some 9 km) to the southeast, attaining an altitude of 3,000 feet, before returning to the ground at the Butte-aux-Cailles, then on the outskirts of Paris. After the flight, the pilots drank champagne to celebrate the flight, a tradition carried on by balloonists to this day.
D'Arlandes proposed a flight to cross the English Channel in 1784, but the plan came to nothing.
He was dismissed from the army for cowardice after the French Revolution, and died in his castle of Saleton near Anneyron. Some sources suggest that he committed suicide.
Jean-François Pilâtre de Rozier (French pronunciation: [ʒɑ̃ fʁɑ̃swa pilɑtʁ də ʁozje]) (30 March 1754 – 15 June 1785) was a French chemistry and physics teacher, and one of the first pioneers of aviation. François Laurent d'Arlandes and he made the first manned free balloon flight on 21 November 1783, in a Montgolfier balloon. He later died when his balloon crashed near Wimereux in the Pas-de-Calais during an attempt to fly across the English Channel. His companion, Pierre Romain, and he thus became the first known fatalities in an air crash.
