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 word 'helicopter' is adapted from the French hélicoptère, coined by Gustave de Ponton d'Amecourt in 1861, which originates from the Greek helix/helik- (ἕλικ-) = 'spiral' or 'turning' and pteron (πτερόν) = 'wing'.
Helicopters were developed and built during the first half-century of flight, with some reaching limited production, but it was not until 1942 that a helicopter designed by Igor Sikorsky reached full-scale production, with 131 aircraft built. Though most earlier designs used more than one main rotor, it was the single main rotor with antitorque tail rotor configuration of this design that would come to be recognized worldwide as the helicopter.

...that in 1929 the Graf Zeppelin completed a circumnavigation of the globe in 21 days, 5 hours and 31 minutes? ...that the airfields captured in the battle of Tinian were used for the atomic bombings of Hiroshima and Nagasaki? ... that on 28 May 1931, a Bellanca CH-300 fitted with a Packard DR-980 diesel engine set a 55-year record for staying aloft for 84 hours and 32 minutes without being refueled?

Jones first saw action as an infantryman in the Gallipoli campaign of 1915, before transferring to the Australian Flying Corps the following year. Initially an air mechanic, he undertook flying training in 1917 and was posted to a fighter squadron in France, achieving seven victories to become an ace. After a short spell in civilian life following World War I, he joined the newly-formed RAAF in 1921, rising steadily through training and personnel commands prior to World War II.
He did not actively seek the position of Chief of the Air Staff before being appointed in 1942, and his conflict with Bostock—with whom he had been friends for 20 years—was partly the result of a divided command structure, which neither man had any direct role in shaping. After World War II Jones had overall responsibility for transforming what was then the world's fourth largest air force into a peacetime service that was also able to meet overseas commitments in Malaya and Korea. Following his retirement from the RAAF he continued to serve in the aircraft industry and later ran unsuccessfully for political office.
NASA's Space Shuttle, officially called the Space Transportation System (STS), was the spacecraft which was used by the United States government for its human spaceflight missions. At launch, it consisted of a rust-colored external tank (ET), two white, slender Solid Rocket Boosters (SRBs), and the orbiter, a winged spaceplane which was the space shuttle in the narrow sense.
The orbiter carried astronauts and payload such as satellites or space station parts into low Earth orbit, into the Earth's upper atmosphere or thermosphere. Usually, five to seven crew members rode in the orbiter. The payload capacity was 22,700 kg (50,000 lb). When the orbiter's mission was complete, it fired its Orbital Maneuvering System (OMS) thrusters to drop out of orbit and re-enter the lower atmosphere. During the descent and landing, the shuttle orbiter acted as a glider, and made a completely unpowered ("dead stick") landing.
