On August 27, 1783, the people of the village of Gomesse, in France, looked up into the sky and saw a strange and terrible animal. It was huge and round, flying down from the sky. It landed in the field just outside the village. It was clear to the people of Gomesse that they had to defend themselves. The animal was clearly some kind of terrible “spirit”. They were afraid of the spirit but they were also very brave. They rushed out into the field and fought the animal with knives and sticks and farming tools. The “spirit” made terrible noises, like an animal that can breathe only with great difficulty.

But that was not the worst thing. When the villagers cut into the spirit's skin, it gave off a horrible smell, and even after the villagers had cut the thing open, it still moved. Finally the villagers tied it to a horse. The horse ran through the fields and the “Spirit” was torn to pieces. What was the terrible spirit? The answer is that it was one of the first “hot air balloons气球”. Its skin was made of silk and a kind of rubber. The terrible smell was the hot air inside the balloon.
