Public demonstration of the montgolfière at Annonay
- When
- 4 June 1783
- Where
- Place des Cordeliers, Annonay
The Montgolfier brothers flew their sackcloth balloon from the Place des Cordeliers at Annonay before dignitaries of the états particuliers.
Having conducted private tests in December 1782, the brothers built a globe-shaped balloon of sackcloth tightened with three thin layers of paper inside to make a public demonstration and claim the invention. On 4 June 1783 they flew it at Annonay, precisely from the Place des Cordeliers, in front of a chosen public of dignitaries from the états particuliers, particularly members of state of Vivarais. This was the first public official flight in a hot air balloon.
