FLYGAS ~ in the NEWS! Jean-Francois Pilatre de Rozier was a daredevil balloonist and a patriot. He threw himself into the quest to build a balloon that would get to England. He had previously tried twice, and failed. One of the main problems was that a hot air balloon — which was only kept aloft because its heated air was so much less dense than the atmosphere — required massive amounts of fuel to stoke the fire. Wood is not a light substance, so the fuel for the balloon weighed the balloon down. Hydrogen balloons didnt require heavy fuel, but the gas was tough to come by.
