Aviation, or air transport, refers to the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, as well as lighter-than-air craft such as balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through lighter-than-air buoyancy. The most significant advancement in aviation technology came with the construction of the first aeroplane in the early 1900s. Since this time, aviation has been technologically revolutionised with the introduction of the jet and has become a major form of transport throughout the world.

Gliding is a recreational activity and competitive sport where pilots fly un-powered aircraft known as gliders or sailplanes. Properly, the term gliding refers to descending flight of a heavier-than-air craft, whereas soaring is the correct term to use when the craft gains altitude or speed from rising air. After launching glider pilots search for rising air to gain height. If conditions are good enough, experienced pilots can fly many hundreds, or even thousands, of kilometers before returning to their home airfields. However if the weather deteriorates, they must often land elsewhere, but some can avoid this by using engines. While many glider pilots merely enjoy the sense of achievement, some competitive pilots fly in races round pre-defined courses. These competitions test the pilots' abilities to make best use of local weather conditions as well as their flying skills. Local and national competitions are organized in many countries and there are also biennial World Gliding Championships. Powered aircraft or winches are the most common methods of launching gliders. These and other methods (apart from self-launching motor-gliders) require assistance from other participants. Gliding clubs have thus been established to share airfields and equipment, train new pilots and maintain high safety standards. (more...)

• 2000 - Lockheed-Martin X-35C, the Navy version of the Joint Strike Fighter, makes its first flight at Edwards Air Force Base.

• 1948 - The Northrop X-4 Bantam makes its first flight at Muroc Army Air Field.

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).

Orville Wright

Wilbur Wright

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.
