The First Giant of the Air
1. When most people hear the name of Leonardo da Vinci they think of the wonderful paintings in the best world museums. But his genious was manysided and remarkable. He was one of the greatest artists and scientists in the history of the world. He had a lot of sketches for a submarine, heavy artillery, naval rocket missiles, armoured cars, the first practical parachute and helicopter and many other things.

2. Leonardo da Vinci was the first man to make a scientific study of bird flight. "A bird is an instrument", he observed, "Working to mathematical laws. He discovered many of these laws. He learned how birds balanced themselves, soared in spirals to gain height, flew with and against the wind. He was the first man to understand the main prin­ciples of flight control. He realized that a bird's wing compresses air beneath it, which gives it lift.

3 Leonardo da Vinci might well have been the first man to fly. When he was a child, an eagle flew over his bed. It hovered over the boy and then with a tremendous beaking of the wings it rose and flew away. This was the boy's earliest memory. He never forgot it. Even as a boy, he was determined to master the air.

4 When he died, his blue-prints were lost, hidden or sold. They were not collected and published in one book until the end of the 19th century. But then other men had re-discovered all that he had known four hundred years before. But his work had at least one very definite result. It directly inspired Igor Sikorsky, a Russian, to make the first really successful helicopter.
