of various shapes and sizes. During the fall and early winter of 1901, the Wrights tested between 100 and 200 wing designs. The brothers then began work on their third full-scale glider. They tested the machine at the Kill Devil Hills in September and October of 1902. For the first time, the brothers shared the flying duties, completing 700–1,000 flights, covering distances up to 622.5 feet, and remaining in the air for as long as 26 seconds.
The brothers then returned to Kill Devil Hills in September 1903. They spent the next seven weeks assembling, testing, and repairing their powered machine and conducting new flight tests with the 1902 glider. Wilbur made the first attempt at powered flight on December 14, but he stalled the aircraft on take-off and damaged the forward section of the machine. Three days were spent making repairs and waiting for the return of good weather.
Then, at about 10:35 on the morning of December 17, 1903, Orville made the first successful flight, covering 120 feet through the air in 12 seconds. Wilbur flew 175 feet in 12 seconds on his first attempt, followed by Orville’s second effort of 200 feet in 15 seconds. During the fourth and final flight of the day, Wilbur flew 852 feet over the sand in 59 seconds. For the first time in history, a heavier-than-air machine had demonstrated powered and sustained flight under the complete control of the pilot.
Determined to move from the marginal success of 1903 to a practical airplane, the Wrights in 1904 and 1905 built and flew two more aircraft from
Huffman Prairie in Dayton. They continued to improve the design of their machine during these years, gaining skill and confidence in the air.
By October 1905 the brothers could remain aloft for up to 39 minutes at a time, performing circles and other maneuvers. The Wrights decided to cease flying and remain on the ground until their invention was protected by patents and they had negotiated a contract for its sale.
In February 1908 the Wrights signed a contract for the sale of an airplane to the U.S. Army. They would receive $25,000 for delivering a machine capable of flying for at least one hour with a pilot and passenger at an average speed of 40 miles per hour. The Wright brothers returned to the Kill Devil Hills in May 1908, where they made 22 flights with their old 1905 machine, modified with upright seating and hand controls.
