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. 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...)

Ryanair is an airline based in Ireland. It is Europe's largest low-cost carrier, operating 209 low-fare routes to 94 destinations across 17 European countries. Over the years it has evolved into the world's most profitable airline, running at remarkable margins by relentlessly driving costs down. Ryanair has been characterised by rapid and continuing expansion, enabled by the deregulation of the air industry in Europe in 1997. It operates a fleet of 74 Boeing 737s, and currently has firm orders for an additional 225 Boeing 737-800 airplanes by 2010, with options on a further 193. Ryanair is one of Europe's most controversial companies, praised and criticised in equal measure. Its supporters praise its commitment to exceptionally low fares, its radical management, its populism, and its willingness to challenge what Ryanair calls the 'establishment' within the airline industry. Critics, meanwhile, have attacked its labor union policies, and have charged that it practises deceptive advertising. (Full article...)

Selected biography

Jeana Yeager (born May 18, 1952 in Fort Worth, Texas) is an aviator, most famous for flying with Dick Rutan on a non-stop, non-refueled flight around the world in the Voyager aircraft from December 14 to December 23, 1986. The flight took 9 days, 3 minutes, and 44 seconds and covered 24,986 miles (40,211 km), more than doubling the old distance record. She received the US annual Harmon Trophy for outstanding international achievements in the aeronautics, and is the first woman recipient of the Collier Trophy for "the greatest achievement in aeronautics in America, with respect to improving the performance, efficiency, and safety" of aircraft.

Despite her surname, Jeana Yeager is not related to Chuck Yeager, the first man to break the sound barrier in level flight.

Selected Aircraft

The de Havilland Canada DHC-8, popularly the Dash 8, is a series of twin-turboprop airliners designed by de Havilland Canada in the early 1980s. They are now made by Bombardier Aerospace which purchased DHC from Boeing in 1992. Since 1996 the aircraft have been known as the Q Series, for "quiet", due to installation of the Active Noise and Vibration Suppression (ANVS) system designed to reduce cabin noise and vibration levels to near those of jet airliners.

Notable features of the Dash 8 design are the large T-tail intended to keep the tail free of propwash during takeoff, a very high aspect ratio wing, the elongated engine nacelles also holding the rearward-folding landing gear, and the pointed nose profile. First flight was in 1983, and the plane entered service in 1984 with NorOntair. Piedmont Airlines (formerly Henson Airlines) was the US launch customer for the Dash 8 in 1984.

The Dash 8 design had better cruise performance than the earlier Dash 7, was less expensive to operate, and more notably, much less expensive to maintain. The Dash 8 had the lowest costs per passenger mile of any feederliner of the era. The only disadvantage compared to the earlier Dash 7 was somewhat higher noise levels, but only in comparison as the Dash 7 was notable in the industry for extremely low noise due to its four very large and slow-turning propellers.
