In 1889, with Wilbur's help, Orville designed and built a printing press, and the brothers began publishing a weekly and then a daily paper. In 1892 they opened a bicycle shop, and in 1896 started manufacturing their own brand. Orville invented a self-oiling wheel hub. That year German aviator Otto Lilienthal died in a glider crash, but his pioneering work showed that manned flight was feasible. French aviation researcher Octave Chanute collected data and brought together young aviators to experiment with gliders on the sand dunes at the Lake Michigan shore. The Wright brothers interest in flight was renewed, and they set about to learn everything they could about the subject, gathering and reading whatever they could, and later designing experiments of their own.
To provide adequate lift for large gliders, the Wright brothers needed to find a place with more wind than was typical anywhere near Dayton. In November 1899, Wilbur wrote to Willis L. Moore, Chief of the U.S. Weather Bureau, asking about high wind conditions throughout the country. The first rural place on the list Moore sent back was Kitty Hawk, North Carolina. During the years 1900, 1901, and 1902, Orville and Wilbur experimented at Kitty Hawk with kites, gliders, and a wind tunnel they built to test wing design. The Wright brothers developed the first effective airplane, and made the historic first airplane flight in 1903.
In 1905, the Wright brothers built an airplane that could fly for more than half an hour at a time. In 1908 Orville made the world's first flight of over one hour at Fort Myer, Virginia, in a demonstration for the U.S. army, which subsequently made the Wright planes the world's first military airplanes. That same year Wilbur made over 100 flights near Le Mans, France; the longest one, on Dec. 31, a record flight: 2 hours, 19 minutes.
The brothers never married. Wilbur Wright died at age 45 of typhoid. Orville Wright died of a heart attack at age 77.
