Alfred Victor Verville (November 16, 1890 – March 10, 1970) was an aviation pioneer and aircraft designer who contributed to civilian and military aviation.
 During his forty-seven years in the aviation industry, he was responsible for the design and development of nearly twenty commercial and military airplanes.
 Verville is known for designing flying boats, military racing airplanes (such as the record breaking Verville-Sperry R-3 Racer), and a series of commercial cabin airplanes.
 His planes were awarded with the Pulitzer Speed Classic Trophy in 1920 and 1924.
The Aviation Squadrons of the Ottoman Empire were military aviation units of the Ottoman Army and Navy.
 The history of Ottoman military aviation dates back to June 1909 or July 1911.
 The organisation is sometimes referred to as the Ottoman Air Force.
 The fleet size reached its apex in December 1916, when the Ottoman aviation squadrons had 90 airplanes.
 The Aviation Squadrons were reorganized as the General Inspectorate of Air Forces ("Kuva-yı Havaiye Müfettiş-i Umumiliği") on 29 July 1918.
 With the signing of the Armistice of Mudros on 30 October 1918, the Ottoman military aviation effectively came to an end.
 At the time of the armistice, the Ottoman military aviation had around 100 pilots; 17 land-based airplane companies (4 planes each); and 3 seaplane companies (4 planes each); totalling 80 aircraft.
"Podpolkovnik" Yevgraf Nikolaevich Kruten was a World War I flying ace credited with seven aerial victories.
 He began World War I as an aerial observer with three years experience in military aviation.
 After a year's seasoning, he was recommended for, and graduated from, pilot's training in September 1914.
 He rose through the ranks, to be appointed as his unit's commander on 6 June 1916.
 With his victory tally at three, he was forwarded to service with the French .
 While learning French aerial tactics, Kruten shot down a German aircraft during February 1917.
 After his return to Russia in March 1917, he shared his new-found knowledge in a flurry of booklets on military aviation.
 He commanded his battle group of three detachments, and ran his victory total to seven before dying in a landing accident on 19 June 1917.
Military aviation occupations are types of work either shared with commercial aviation or unique to military aviation, that provide skills for the operation of an air forces business.
 Often military aviation employees will have had higher education due to the complexity of the electrical and mechanical systems involved in aircraft design and maintenance, in ground operations, in control of airspace and in the air.
Donovan Reese Berlin (June 13, 1898 – May 17, 1982) was an American military aircraft designer and aircraft industry executive.
 Among the many designs with which he is associated, are the Curtiss P-36 Hawk, Curtiss P-40 Warhawk and Fisher P-75 Eagle.
 His name is "synonymous with the development of military aviation".
 He designed aircraft that were safe, rugged and "a pilot's joy."
The Curtiss P-40 Warhawk is an American single-engined, single-seat, all-metal fighter and ground-attack aircraft that first flew in 1938.
 The P-40 design was a modification of the previous Curtiss P-36 Hawk which reduced development time and enabled a rapid entry into production and operational service.
 The Warhawk was used by most Allied powers during World War II, and remained in frontline service until the end of the war.
 It was the third most-produced American fighter, after the P-51 and P-47; by November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation's main production facilities at Buffalo, New York.
Mikhail Iosifovich Gurevich (Russian: Михаи́л Ио́сифович Гуре́вич ) (12 January 1893 [O.S. 31 December 1892] – November 12, 1976) was a Soviet Jewish aircraft designer, a partner (with Artem Mikoyan) who co-founded the famous MiG military aviation bureau.
 MiG is an abbreviation of their surnames.
 The bureau now simply known as Mikoyan, is famous for its fighter aircraft, rapid interceptors and multi-role combat aircraft which were staples of the Soviet Air Forces throughout the Cold War.
 The main focus in designing the aircraft were on high speed, fast ascent, and high flight altitude.
 The bureau designed 170 projects of which 94 were made in series.
 In total 45000 aircraft of "MiG" brand have been manufactured domestically, of which 11000 aircraft were exported.
 Over 14000 "MiG" fighters have been produced under licence abroad.
 The last plane which Gurevich personally worked on before his retirement was the Mig-25.
The Italian Corpo Aeronautico Militare (Military Aviation Corps) was formed as part of the part of the Regio Esercito (Royal Army) on 7 January 1915, incorporating the Aviators Flights Battalion (airplanes), the Specialists Battalion (airships) and the Ballonists Battalion.
 Prior to World War I, Italy had pioneered military aviation in the Italo-Turkish War during 1911–1912.
 Its army also contained one of the world's foremost theorists about the future of military aviation, Giulio Douhet; Douhet also had a practical side, as he was largely responsible for the development of Italy's Caproni bombers starting in 1913.
 Italy also had the advantage of a delayed entry into World War I, not starting the fight until 24 May 1915, but took no advantage of it so far as aviation was concerned.
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 or military aviation.
 Although the International Civil Aviation Organization (ICAO) excludes any form of remunerated aviation from its definition, some commercial operations are often included within the scope of general aviation (GA) 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.
 Other commercial GA activities are aerial work, such as surveying and air ambulances, and flight training, which plays an important role in the supply of pilots to the commercial air transport (CAT) industry.
 Private flying is conducted for personal transport and recreation.
 It includes a strong vintage aircraft movement, and encompasses a range of air sports, such as racing, aerobatics, and parachuting, at which British teams and individuals have succeeded in international competition.
Wings was a military aviation history magazine published in the United States between 1971 and 2007.
 The magazine featured articles and photo features covering military aviation from World War I to the modern era, focusing heavily on American aircraft.
