Hot air ballooning began in France in the 17th century. Two brothers, Joseph and Enttienne Mongolfier saw smoke rising from the chimneys in a nearby town. They first thought that it was the smoke property that had rising effects. They later understood that it was the heat that made the balloon rise. The first passengers in the balloon were a rooster, duck, and a sheep. Ballooning was an amazing idea, but controlling the heat flow to the envelope was difficult and dangerous. Hot air ballooning was virtually ignored for a couple of hundred years but was reinvented with the technology of the 1950's. Balloonists learned about new gasses and special ways to control the propane and heat flow. That is when hot air ballooning really ... took off!
