As we saw before holidays, scientists began to use fire and the weight difference between hot and cold air to make balloon fly. The major problem was that tissue from balloon is easily burnable. To avoid this possibility, physicist Jacques Charles and tissue trader Robert did together the first flight with gas lighter than air. They used hydrogen that had been recently discovered and extracted. This invention had been done in 1783. One year after that, Elisabeth Tible was the first women to flight.
In 1783 happened the first crash. Pilatre de Rozier wanted to cross the English Channel from France to England as it had been done by Blanchard in the other way. Concequences were terrible, the French chemistry and physics teacher died. At this moment people realised that with "aviation", consequences were terrible.
Only 9 years after that, balloon was used as military instrument. In fact, it helped to keep an eye over enemies during wars. In 1821, lighting gas took place of hydrogen because it was less expensive but was as burnable as it. Finally after 19th century, as guidance couldn't be manage, balloon was used for science experiences or entertainment.
As we said the major problem was that balloon couldn't be manage. To correct that, arrived the idea to put propeller in order to manage guidance. In 1783, French general Meunier drew the first airship with propeller that was powered by humans. This innovation only had been created one century after that... thanks to motors.
