Man has dreamed of flight for thousands of years. From the beginning we have watched birds fly and imagined the possibilities of being free from the earth's surface. However, it took hundreds of years for us to understand our world and the forces in it well enough to make it possible for humans to fly through the air.

First, we needed to understand the stuff the earth and air were made of. We invented and discovered ways of measuring things so that we could classify and sort them. With this knowledge man has developed theories to explain and predict how and why the earth and air behaves the way it does and eventually learned to harness their power so that we could build the engines and wings needed to get off the ground so that we could soar with the birds. The science of building an airplane is called aeronautics.
