Flying has always been one of man's greatest advances. From the skies of the First World War to the birds that flutter. The airplane has created such an amazing transportation revolution around the world. Approximately 4.5 million people use an airplane every day for personal or business use. Orville and Wilbur Wright, with the help of thousands of years of research, created the first powered aircraft controlled and sustained in flight with a pilot on board. The number of years spent working on the first plane alone was 6 years. They began research and planning in 1899, until their first success in 1905 in Kitty Hawk, North Carolina. The plane was called the Wright Flyer and went down in history as the first piloted airplane. In the beginning, Wilbur and Orville Wright were simple men who owned a small bicycle shop in Greenfield Village, North Carolina. They were simple men with simple jobs, like the bicycle shop and the newspaper. The West Side News was theirs, with Wilbur as editor and Orville as printer. During the year 1896 their curiosity soared when a headline ran through many newspapers across America. The very famous Otto Lilienthal had died from injuries sustained in a glider crash. From then on the idea of ​​human flight had interested both brothers in acting in favor of aerodynamics. They began work 2 years later, in 1899. On May 30, 1899, Wilbur wrote a message to the Smithsonian: "Dear Sirs: I am an enthusiast, but not an eccentric, in the sense of having some favorite theories as to the proper construction of a flying machine. I wish make use of everything that is already known and then, if possible, add my contribution to help the future worker who will achieve the final success. Kind regards Wilbur Wright”… in the middle of the paper… instead of achieving it lower than the brothers' calculations predicted that the change in wing curvature from 1/23 to 1/12 would lift the airplane more. Instead it created its own problems with elevator and pitch control they would quickly resolve to a shallower curvature than 1/19 This solution would help greatly with control, but lift would remain poor. All in all, the flight attempts were a disaster and a downside story, but it didn't get the results they were looking for. He had problems with lift and control, two of the most important factors for flight. Although they had some success, the glider reached a height of 90 meters (300 ft).
