Hot air balloons were around in the 1700s. The first hot air balloon ever was built in France, 1783. The first passengers were a sheep, a duck and a rooster. People back then were afraid of heights.
Eventually, in August, the first human passengers boarded the hot air balloon in France, the same location where the first balloon was built.
In 1809, a balloonist named Blanchard crossed the English Channel successfully. Unfortunately, he died because of a balloon accident and crash-landed somewhere near France.
Forty years later, Austria had a use of the hot air balloon: aerial bombing. They were defending Venice from German attack.
Hot air balloons have an ‘envelope’ and a ‘gondola’. The envelope expands thanks to a burner under the the hole and above the gondola. Hot air expands in the envelope. Hot air is lighter than cold air, so it takes up a lot of space. When the envelope rises, it pulls the gondola with it.
