After studying Lilienthal and Cayley, the Wright brothers flew their first gliders in 1899. In 1900 they went to Kill Devil Hills, North Carolina to pursue the glider experiments. Orville and Wilbur became master glider builders and experts on wing aerodynamics through numerous experiments in a wind tunnel. Through their wind tunnel test, they found an error in Otto Lilienthal\'s lift formulas. They also discovered that the symmetrical curve of Lilenthal\'s wing was unstable and improved it by placing the apex of the curve about 1/4 distance back from the leading edge.
