An airplane or aeroplane(informally plane) is a powered,fixed-wing aircraft that is propelled forward by thrust from ajet engine,propellero rocket engine. 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. Worldwide,commercial aviation transports more than four billion passengers annually on airliner sand transports more than 200 billion tonne-kilo meters of cargo annually, which is less than 1% of the world's cargo movement.Most airplanes are flown by a pilot on board the aircraft, but some are designed to beremotely or computer-controlled such as drones.

The Wright brothers invented and flew the first airplane in 1903, recognized as "the first sustained and controlled heavier-than-air powered flight".They built on the works of George Cayley dating from 1799, when he set forth the concept of the modern airplane (and later built and flew models and successful passenger-carrying gliders).Between 1867 and 1896, the German pioneer of human aviation Otto Lilienthal also studied heavier-than-air flight. Following its limited use in World War I, aircraft technology continued to develop. Airplanes had a presence in all the major battles of World War II. The first jet aircraft was the German Heinkel He 178in 1939. The first jet airliner, thede Havilland Comet, was introduced in 1952. The Boeing 707, the first widely successful commercial jet, was in commercial service for more than 50 years, from 1958 to at least 2013.

The Wright brothers—Orville and Wilbur —were two American  aviation pioneers generally credited with inventing, building, and flying the world's first successful motor-operated air plane. They made the first controlled, sustained flight of a powered,heavier-than-air aircraft with the Wright Flyeron December 17, 1903, 4mi (6km) south of Kitty Hawk, North Carolina. In 1904–05, the brothers developed their flying machine to make longer-running and more aerodynamic flights with the Wright Flyer II, followed by the first truly practical fixed-wing aircraft, the Wright Flyer III. The Wright brothers were also the first to invent aircraft  made fixed-wing powered flight possible.
