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...)

Had it been successful, the planned amphibious and airborne landings in Britain of Operation Sea Lion would have followed. The Battle of Britain was the first major campaign to be fought entirely by air forces. It was the largest and most sustained bombing campaign attempted up until that date. The failure of Nazi Germany to destroy Britain's air defence or to break British morale is considered its first major defeat.
British historians date the battle from 10 July to 31 October 1940, which represented the most intense period of daylight bombing. German historians usually place the beginning of the battle in mid-August 1940 and end it in May 1941, on the withdrawal of the bomber units in preparation for the attack on the USSR.

Selected biography
Born in Earlsdon, Coventry, England on June 1, 1907, Whittle left Leamington College in 1923 to join the Royal Air Force (RAF). Through his early days as an Aircraft apprentice he maintained his interest in the Model Aircraft Society where he built replicas, the quality of which attracted the eye of his commanding officer, who was so impressed that he recommended Whittle for the Officer Training College at Cranwell in Lincolnshire in 1926, a rarity for a "commoner" in what was still a very class-based military structure. A requirement of the course was that each student had to produce a thesis for graduation. Whittle decided to write his thesis on future developments in aircraft design, in which he described what is today referred to as a motorjet.
Whittle and Hans von Ohain met after the war and initially Whittle was angry with him as he felt Ohain had stolen his ideas. Ohain eventually convinced him that his work was independent and after that point the two became good friends.
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.
