Considered - thousands of years - an unattainable dream, the flight takes passionate people and made them the oddest invent machines that try to get up in the air. But only a century ago, the Wright brothers achieved, in America, the first flight with a heavier than air. Their airplane flew a few meters. From then until today, have come to do airplanes fly between continents, with a speed that exceeds that of sound. These performances are the result of great inventors, who most often piloted his own aircraft, risking his life.
The dream of flying began with the legend of Icarus, who is said that he made two wings of wax and feathers stuck up in the air, approaching the sun. But because of the heat, the wax melted and Icarus plunged.
In the Renaissance, the famous Leonardo da Vinci thought, among other fantastic machines, to a device with which man can fly. Carefully studied the flight of birds, he designed a machine called orthoptera. Its wings would have to be moved while the hands and feet of a man, something which is impossible. Leonardo's plans then fell into oblivion for a long time.
Later, in the eighteenth century, Italian priest Francesco da Lana, imagines itself a flying boat, which ought to be able to lift into the air by four metal balls, purged of air. This fantastic project remained unrealized. However, towards the end of the eighteenth century, the man managed to climb to the sky filled with hot air balloon. In the next century the first gliders are built by Otto Lilienthal, who was killed in one such attempt to conquer the air. But glider was the first step towards building a heavier than air to move under its own power. It will be the airplane or aeroplane. read more...
