Document Summary

Humans have long yearned to fly as represented in the greek myth of icarus. In the 15th century leonardo da vinci designed various flying machines (including designs for helicopters) but did not have the engineering skills to complete the designs. In the 19th century, otto lilienthal performed more than 2000 glider flights using his own designs. He perished in 1886 after a glider mishap. A fluid that is moving faster has a relatively lower pressure. The shape of a wing causes air to flow faster over the top of the wing than it does beneath. This produces a lower pressure above the wind and a higher pressure below the wing; creating a pressure gradient force pushing upward. The wing experiences a lift and thus flight is enabled. In 2000, 8,000 commercial flights were taking place at any given moment, carrying 1,000,000 passengers.
