Aviation includes the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft such as hot air balloons and airships.
Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This is the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. (Full article...)

The Wright brothers, Orville Wright (August 19, 1871 - January 30, 1948) and Wilbur Wright (April 16, 1867 - May 30, 1912), are generally credited with making the first controlled, powered, heavier-than-air flight on December 17, 1903. In the two years afterward, they developed their flying machine into the world's first practical airplane, along with many other aviation milestones.
In 1878 Wilbur and Orville were given a toy "helicopter" by their father. The device was made of paper, bamboo and cork with a rubber band to twirl its twin blades, and about a foot long. The boys played with it until it broke, then built their own. In later years, they pointed to their experience with the toy as the initial spark of their interest in flying.
The Douglas DC-3 is a fixed-wing, propeller-driven aircraft which revolutionized air transport in the 1930s and 1940s, and is generally regarded as one of the most significant transport aircraft ever made.
The DC-3 was engineered by a team led by chief engineer Arthur E. Raymond and first flew on December 17, 1935 (the 32nd. anniversary of the Wright Brothers flight at Kitty Hawk). The plane was the result of a marathon phone call from American Airlines CEO C.R. Smith demanding improvements in the design of the DC-2. The amenities of the DC-3 (including sleeping berths on early models and an in-flight kitchen) popularized air travel in the United States. With just one refuelling stop, transcontinental flights across America became possible. Before the DC-3, such a trip would entail short hops in commuter aircraft during the day coupled with train travel overnight.
During World War II, many civilian DC-3s were drafted for the war effort and thousands of military versions of the DC-3 were built under the designations C-47, C-53, R4D, and Dakota. The armed forces of many countries used the DC-3 and its military variants for the transport of troops, cargo and wounded. Over 10,000 aircraft were produced (some as licensed copies in Japan as Showa L2D, and in the USSR as the Lisunov Li-2).
