We finished the last article with Lalande and his scientists team that made a study, in 1782, to prove that humans could never flight as they are too heavy to stay in the air.
Only one year after this study, Mongolfière brothers launched the first hot air balloon test. At this stage of the history there were two sides that are facing each other, from the first side, the ones that wanted to make flight heavy machines, but this people had to wait three centuries to move forward thanks to motors.
The other side is the one that made aviation progressed between 1700 and 20th century. These people thought that, to fly they had to use force of "lighter than air" component as helium.
Jean-Marie Le Bris made fly a homemade sailplane in 1856. His plane was on a wagon and towed by a horse. He succeed to flight with it and be the first to consider wings incidence for flight direction control. Le Bris used for his experience, the horse as a motor to make fly his heavy engine.
Except this event, during almost three centuries all innovations were into the "lighter than air" side.
As said before, Mongolfière brothers made, the 19th of September 1783, the first hot air balloon. The idea came by looking at paper raise in a fireplace. As the idea this invention used hot air as a leverage to raise the balloon. For the history, the first test was in front of Louis XVI and the first passengers were a sheep, a duck and a chicken. One month after, the 19th of october 1783, the first try with humans happened. The balloon was locked to the ground with a rope. The balloon went 120 meters above floor and the first passengers were the chemistry and physics teacher, Pilatre de Rozier, who is also considered as an aviation pioneer.
