history of the first airplane flight

The first flight carried out on 17 December 1903 at Kill Devil Hill near Kitty Hawk, North Carolina. Each of the two brothers had made two flights on that day. The first flight, which carried Orville Wright lasted 12 seconds and reaches a distance of 120 feet. The last flight, which carried Wilbur Wright, lasts 59 seconds and reaches a height of 852 feet. The plane who they named Flyer I (now known by the nickname Kitty Hawk) takes the cost of manufacture less than 1000 dollars. The plane had a wing 40 feet long and weighs about 750 pounds, measuring 12-horsepower engine, weighing only 170 pounds. The original aircraft is now stored neatly in the Air and Space Museum Washington DC
Although there are five witnesses when the first flight, relatively little was reported by the newspapers on the issue the next day (and it was generally less accurate). His own town newspaper in Dayton Ohio at all think nothing of this business. Only five years after the world was generally realized that human flight really can happen.


After their flight at Kitty Hawk, the Wright brothers returned to his hometown in Dayton. There, they design and make to-2 aircraft, Flyer II. With the second pilot of this flight they did 105 times in 1904 without attracting public attention at all. Flyer III airplane who have been refined and made more practical in 1905. Although they are many times the air near the town of Dayton, many people still believe that morbidly thing as an airplane in the world was born. In the year 1906 - for example - newspapers Paris edition of The Herald Tribune article titled lower Flyer or Liars? (Flight or pengibulan).
In 1908 they finally wipe out all the indecision and general mistrust. Wilbur Wright flew the plane to France, make a demonstration of acrobatics in the air and organizing companies to market their creations. Meanwhile, in the United States, Orville Wright presents similar performances. Unfortunately, on 17 September 1908 crashing his plane crashed. This is the only accident ever experienced by both of them. One passenger was killed, Orville broken leg and two ribs, but soon recover. The successful flight stirs the United States government signed a contract to make planes for the United States Department of Defense, and in 1909 the government budget there is an order worth $ 30,000 for the purposes of the Air Force.


There was once a legal dispute involving patent rights between the Wright brothers with his rivals, but in 1914 the court rejected their demands. What was about to say, in 1912 Wilbur Wright got typhoid and died at the age of forty-five years. Orville Wright who in 1915 sold his shares to a company, lived until 1948. Neither of the two brothers were ever mating.
Although many investigations in this field who preceded him, no doubt Wright bersaudaralah reply can be regarded as a forerunner to the discovery of an airplane. Within the determination of the order on the list this book, which become the main grip is the creation of an aircraft has meaning is less important than the invention of printing or both of steam power who had constructed a revolutionary overhaul of human livelihoods. However, undoubtedly the discovery of an aircraft who is an important historical phenomenon, both in the event of use for the purposes of peace or war. Only within tens of years after that date, the aircraft had constructed our world is so shrunken space even any taste can be touched fingers. And further than that, the discovery of a human plane laden beginners and opening the way for flight in outer space.
