Where did the first major public demonstration of the unmanned balloon occur in June 1783?
Answer
Annonay
The first significant public demonstration showcasing the capability of their invention took place in June 1783 in Annonay, the hometown of the Montgolfier brothers. For this critical proof-of-concept flight, they inflated a large envelope constructed of paper and fabric by using straw and wool as the fuel source to generate the necessary hot air. The unmanned balloon ascended successfully into the air, which was significant enough to warrant informing local officials. This successful demonstration was crucial as it validated their design and provided the necessary evidence to secure an audience with the French court in Paris for further, more high-profile testing.
