The Science of Aviation

The Science of aviation had developed greatly over the years. Leonardo da Vinci made experimental models of flying machines int the fifteenth century. A frenchman, de Rogier made the first baloon flight in 1873. In 1843, an Engishman, Henson made a model of a steam-power aircraft. Henri Gifford flew the first steam-powered, lighter-than-aircraft in 1853. In 1891, Otto Lilienthal made the first glider in Germany. In the early twentieth century, the first engine-powered, heavier-then-airplanes were made and flown by the North Americans, Orville and Wilbur Wright, and the Brazilian, Alberto Santos-Dumont.
