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 craft 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. 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...)

General aviation in the United Kingdom has been defined as a civil aircraft operation other than a commercial air transport flight operating to a schedule. Although the International Civil Aviation Organization excludes any form of remunerated aviation from its definition, some commercial operations are often included within the scope of general aviation in the UK. The sector operates business jets, rotorcraft, piston and jet-engined fixed-wing aircraft, gliders of all descriptions, and lighter than air craft. Public transport operations include business (or corporate) aviation and air taxi services, and account for nearly half of the economic contribution made by the sector. There are 28,000 Private Pilot Licence holders, and 10,000 certified glider pilots. Although GA operates from more than 1,800 aerodromes and landing sites, ranging in size from large regional airports to farm strips, over 80 per cent of GA activity is conducted at 134 of the larger aerodromes. GA is regulated by the Civil Aviation Authority, although regulatory powers are being increasingly transferred to the European Aviation Safety Agency. The main focus is on standards of airworthiness and pilot licensing, and the objective is to promote high standards of safety. (Full article...)

Schlieren photography (from the German word for "streaks") allows the visualization of density changes, and therefore shock waves, in fluid flow. Schlieren techniques have been used for decades in laboratory wind tunnels to visualize supersonic flow about model aircraft, but not full scale aircraft until recently. Dr. Leonard Weinstein of NASA Langley Research Center developed the first Schlieren camera, which he calls SAF (Schlieren for Aircraft in Flight), that can photograph the shock waves of a full sized aircraft in flight. He successfully took a picture which clearly shows the shock waves about a T-38 Talon aircraft on December 13, 1993 at Wallops Island, MD. The camera was then brought to the NASA Dryden Flight Research Center because of the high number of supersonic flights there.

Selected biography

Portrait of Flynn taken in 1929.

The Reverend John Flynn (25 November 1880 – 5 May 1951) was an Australian Presbyterian minister and aviator who founded the Royal Flying Doctor Service, the world's first air ambulance.

Throughout his ministerial training, Flynn had worked in various then-remote areas through Victoria and South Australia. As well as tending to matters spiritual, Flynn quickly established the need for medical care for residents of the vast Australian outback, and established a number of bush hospitals. By 1917, Flynn was already considering the possibility of new technology, such as radio and the aeroplane, to assist in providing a more useful acute medical service, and then received a letter from an Australian pilot serving in World War I, Clifford Peel, who had heard of Flynn's speculations and outlined the capabilities and costs of then-available planes. Flynn turned his considerable fund-raising talents to the task of establishing a flying medical service.

The first flight of the Aerial Medical Service was in 1928 from Cloncurry. In 1934 the Australian Aerial Medical Service was formed, and gradually established a network of bases nationwide. Flynn remained the public face of the organisation (through name changes to its present form) and helped raise the funds that kept the service operating.

Selected Aircraft

[[File:|right|250px|]] The Tupolev TB-3 (Russian: Тяжёлый Бомбардировщик, Tyazholy Bombardirovschik, Heavy Bomber, civilian designation ANT-6) was a heavy bomber aircraft which was deployed by the Soviet Air Force in the 1930s and during World War II. It was the world's first cantilever wing four-engine heavy bomber. Despite obsolescence and being officially withdrawn from service in 1939, TB-3 performed bomber and transport duties through much of WWII. The TB-3 also saw combat as a Zveno project fighter mothership and as a light tank transport.

  • 2009 – A Tupolev Tu-142 of the Russian Navy’s Pacific Fleet crashes in the Tatar Strait some 12 miles (19 km) off Sakhalin Island. All eleven crew are missing, presumed dead.
  • 2007 – Romanian Air Force IAR-330 SOCAT attack helicopter belonging to the 90th Airlift Base crashed in Ungheni, 30 km south of Piteşti, Argeş county, southern Romania. Immediately after touching the ground, the aircraft exploded, as it was already on fire. All three crew members aboard were killed, including Commander Nicolae Bucur, who was one of the most experienced pilots of the Romanian Air Force, with over 2,700 flying hours.

The pilot was unable to maintain control due to violent buffeting, and he ordered the crew to bail out. Five of the seven crew escaped safely, including pilot Lynn Hendrix, rescued by Eglin crash boats and helicopters. Airframe impacts two miles S of the base, in the Choctawhatchee Bay. Sgt. Vernon B.

  • 1936 – Polish Lotnictwo Wojskowe PZL.30 Żubr ("Bison") prototype, a twin-engine bomber design modified from a transport rejected in favour of Douglas DC-2s by LOT Polish Airlines, disintegrates in mid-air when wing structure fails. First flown in March 1936, the uninspired composite design of metal, wood and fabric was the first twin-engined bomber of home design to leave the ground, powered by 680 hp (510 kW) P.Z.L. (Bristol) Pegasus radials, but only 16 Żubrs were completed, most relegated to training, none seeing combat. The Romanian Air Force had shown an interest in the Żubr prototype in 1936, and wanted to buy 24 planes. However, after the prototype crash over Michałowice with two Romanian officers on board, they ordered the PZL.37 Łoś instead. (It should be noted, that the factory published a cover-up story, that the crash was caused by one of Romanians opening the door during flight).

  • 1849 – (12–25) While blockading Venice, the Austrian Navy launches unmanned balloons (Montgolfières) equipped with explosive charges from the deck of the steamship Vulcano in an attempt to bombard Venice. Although the experiment is unsuccessful, it is both the first use of balloons for bombardment and the first time a warship makes offensive use of an aerial device.
  • 1836 – 7-8 – Flight of a Montgolfière covering 722 km from London to Weilburg, passing through Green, Holland and Mason.
