The ornithopter is a machine designed to fly by the flapping of its wings in imitation of wild birds.In 1485, Leonardo da Vinci began to learn the journey of wild birds. He grasped that people are way too heavy, and not strong sufficient, to travel using wings just attached to the arms. For that reason he sketched a computer device where the aviator lies straight down on a plank and works two big, membranous wings using hand levers, base pedals, and something of pulleys.
