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...)

Mitchell deployed to France in 1917 when the United States entered World War I. While there he was promoted to brigadier general and placed in command American combat air units in France. After the war Mitchell was appointed the deputy director of the Air Service became a passionate advocate of air power. In 1921 he set up a demonstration to show the capability of airpower against naval vessels. During the course of the demonstrations aircraft successfully sank a captured German destroyer, the light crusier Frankfurt, and the battleship Ostfriesland.
Mitchell regularly sparred with his superiors over the role of airpower in the military. In 1925 he was reverted to his permanent rank of colonel and was transferred to San Antonio, Texas. Later that year, after a series of aviation accidents he accused Army and Navy leadership of incompetence and "almost treasonable administration of the national defense." In response he was court-martialed for insubordination, found guilty, and sentenced to a five-year suspension from active duty. Mitchell resigned on 1 February 1926 in lieu of serving the sentence. He continued to advocate airpower as a civilian until his death in 1936. In 1942 President Franklin Roosevelt posthumously promoted Mitchell to major general in recognition of his contributions to air power.
The Boeing B-17 Flying Fortress is an American four-engine heavy bomber aircraft developed for the U.S. Army Air Corps (USAAC). Competing against Douglas and Martin for a contract to build 200 planes, the airplane outperformed both the other entries and the Air Corps' expectations. Although losing the contract due to an accident, the Air Corps was so in favor of the B-17 that they ordered 13 B-17s regardless. Evolving through numerous design stages, from B-17A to G, the Flying Fortress is considered the first truly mass-produced large aircraft. From its pre-war inception, the USAAC touted the aircraft as a strategic weapon; it was a high-flying, long-ranging potent bomber capable of defending itself. With the ability to return home despite extensive battle damage, its durability, especially in belly-landings and ditchings, quickly took on mythical proportions.
The B-17 was primarily involved in the daylight precision strategic bombing campaign of World War II against German industrial targets. The United States Eighth Air Force based in England and the Fifteenth Air Force based in Italy complemented the RAF Bomber Command's night-time area bombing in Operation Pointblank, which helped secure air superiority over the cities, factories and battlefields of Western Europe in preparation for Operation Overlord. The B-17 also participated, to a lesser extent, in the War in the Pacific.
