By definition, an airplane is an aircraft with a fixed wing and is powered by propellers or jets. Although it is widely known as transportation as we know it today, it is important to know that airplanes have been developed and improved over the centuries and that some people have dedicated themselves and made great efforts. The Wright brothers, Wilbur and Orville, are known to be the inventors of the propulsion system airplane in the history of aviation. They changed the era of piloted flight when they successfully completed a flight with their machine that took off on power generated by a gasoline combustion engine, flew at uniform speeds, and landed without serious damage. Even before them there were many attempts to conquer the sky. Although these early efforts, in modern times, are regarded as contraptions including kites, hot air balloons, airships, gliders, and other types of aircraft, we cannot deny that the contraptions have made some progress. However, there was a significant change when the Wright brothers decided to tackle the problem of manned flight. They changed the history of the world by improving the direction control method so that this success had a significant impact on this world. Say no to plagiarism.

Based on what they had built in 1902, the brothers decided to build a larger, more upgraded version. From the various data obtained from their wind tunnel experiments, they could plan to design a retractable tail wing to balance the machine, and they connected the tail wing with wing deformation wires to adjust the flight direction . Finally, the plane made a successful flight in 1903 with an internal combustion engine (gasoline engine). What differentiates the Wright brothers' plane from others is that the plane could be controlled for three movements by one pilot; main axes of the aircraft (yaw, pitch and roll) which are currently controlled by the aileron, elevator and rudder respectively. The flight was a significant achievement in aviation. However, as there were only five people, it was a controversial flight at the time as breakdowns in aviation were frequent and repeated, as newspapers erroneously reported on the following day of the flight. The French press did not believe in the success of the Wright brothers and wrote a criticism of them. Most people at that time did not believe that they could fly under power and be able to control the direction of the plane. Despite criticism and inaccurate press reports, constant and growing effort has been put into their project to improve and resolve the pitching problem of the previous flight. So the brothers succeeded once again in 1904. However there was one unresolved problem: stability. To solve the problem, they built a new airplane and flew in 1905. Through the airplane, people could see the potential of airplanes. The Wright brothers overcame complex technical and theoretical issues and contributed for centuries. They were credited with the first practical aircraft and became a telegraph corps of the current form of aircraft. After Kitty Hawk, it was filled with many achievements in aviation, but most of the aircraft's foundation came in the first 20 years. These machines were capable of further travel to other countries through airlines, making circular movements, carrying mail, conducting military missions, dropping bombs in battles and so on.
