AIRPLANES
Orville Wright and his brother Wilbur Wright
An airplane or airplane (informally plane) is a powered fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research.
Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled.
HISTORY OF AIRPLANES
The Wright Brothers Make the First Flight
At Kitty Hawk, North Carolina
Orville Wright (1871-1948) and his brother Wilbur Wright (1867-1912
Wilbur Wright (1867-1912) and Orville Wright (1871-1948) were brothers who ran both a printing shop and a bicycle shop in Dayton, Ohio. The skills they learned from working on printing presses and bicycles were invaluable in trying to design and build a working airplane.
Although the brothers' interest in flight had stemmed from a small helicopter toy from their childhood, they didn't begin experimenting with aeronautics until 1899, when Wilbur was 32 and Orville was 28.
Wilbur and Orville began by studying aeronautical books, then talked with civil engineers, and then began to build kites.

Many stories from antiquity involve flight, such as the Greek legend of Icarus and Daedalus, and the Vimana in ancient Indian epics. Around 400 BC in Greece, Archytaswas reputed to have designed and built the first artificial, self-propelled flying device, a bird-shaped model propelled by a jet of what was probably steam, said to have flown some 200 m (660 ft).[ This machine may have been suspended for its flight.[
Some of the earliest recorded attempts with gliders were those by the 9th-century poet Abbas Ibn Firnas and the 11th-century monk Eilmer of Malmesbury; both experiments injured their pilots.[10] Leonardo da Vinci researched the wing design of birds and designed a man-powered aircraft in his Codex on the Flight of Birds (1502).

Sir Hiram Maxim built a craft that weighed 3.5 tons, with a 110-foot (34-meter) wingspan that was powered by two 360-horsepower (270-kW) steam engines driving two propellers. In 1894, his machine was tested with overhead rails to prevent it from rising. The test showed that it had enough lift to take off. The craft was uncontrollable, which Maxim, it is presumed, realized, because he subsequently abandoned work on it.[14]In 1799, Sir George Cayley set forth the concept of the modern airplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control.[11][12] Cayley was building and flying models of fixed-wing aircraft as early as 1803, and he built a successful passenger-carrying glider in 1853.[13] In 1856, Frenchman Jean-Marie Le Bris made the first powered flight, by having his glider "L'Albatros artificiel" pulled by a horse on a beach.[citation needed] Then Alexander F. Mozhaisky also made some innovative designs. In 1883, the American John J. Montgomery made a controlled flight in a glider.[citation needed] Other aviators who made similar flights at that time were Otto Lilienthal, Percy Pilcher, and Octave Chanute.

In the 1890s, Lawrence Hargrave conducted research on wing structures and developed a box kite that lifted the weight of a man. His box kite designs were widely adopted. Although he also developed a type of rotary aircraft engine, he did not create and fly a powered fixed-wing aircraft.[15]
Between 1867 and 1896 the German pioneer of human aviation Otto Lilienthal developed heavier-than-air flight. He was the first person to make well-documented, repeated, successful gliding flights.
