JSC Russian Aircraft Corporation MiG (Российская самолетостроительная корпорация «МиГ» "Rossyskaya samoletostroitelnaya korporatsiya "MiG""), or RSK MiG, is a Russian aerospace joint stock company.
 Formerly Mikoyan and Gurevich Design Bureau (Russian: Микоя́н и Гуре́вич, МиГ "Mikoyan i Gurevich, MiG"), then simply Mikoyan, JSC MiG is a military aircraft design bureau, primarily designing fighter aircraft.
 Its head office is in Begovoy District, Northern Administrative Okrug, Moscow.
Walter E. Mooney (June 6, 1925 – March 1, 1990) was a MIT educated engineer, aircraft designer, pilot and model aircraft designer who lived in San Diego, California.
 He was well known professionally for his full scale aircraft efforts for Convair division of General Dynamics but more popularly known for the many plans and articles published in the magazines "Model Airplane News", "Boys' Life", and "Aero Modeller" in the 1960s.
 He was once featured as a daredevil glider pilot on the 1973 TV series "Thrill Seekers".

Artem (Artyom) Ivanovich Mikoyan (Russian: Артём Ива́нович Микоя́н ; Armenian: Արտյոմ (Անուշավան) Հովհաննեսի Միկոյան "Artyom (Anushavan) Hovhannesi Mikoyan" ; 5 August [O.S. 23 July] 1905 – 9 December 1970) was a Soviet Armenian aircraft designer.
 In partnership with Mikhail Gurevich he designed many of the famous MiG military aircraft.
The Lavochkin La-168 was a jet fighter developed for the USSR.
 Like the better known Mikoyan MiG-15 which was ultimately selected and went on to become one of the most successful jet fighters of its era, it was designed in response to a 1946 request for an advanced swept-wing jet fighter capable of transonic performance.
 It was to use new turbojet based on the Rolls-Royce Nene in competition with the design bureaus of Artem Mikoyan and Mikhail Gurevich, and Aleksandr Yakovlev.
 A scaled down version of this aircraft would lead to the production of the La-15, which performed well but would be dropped in favor of the MiG-15.
Swen (Sven) Swanson (1897/98 – February 1935) was a Swedish aircraft designer.
 He designed aircraft for various aviation companies in the United States and also designed prototype and experimental airplanes.
 He was known as an innovative aircraft designer.
 He later worked in partnership with Ole Fahlin.
 Swanson started designing airplanes while in his teens and by the time he was in college he had designed his third airplane.
 He founded the Swanson Aircraft Company Inc. and became its chief engineer and president.
 While working for his own company he designed and built the Swanson W-15 Coupe.
 He has been described as a "brilliant man of great capabilities and extreme modesty".
United Kingdom military aircraft serials refers to the serial numbers used to identify individual military aircraft in the United Kingdom.
 All UK military aircraft are allocated and display a unique serial number.
 A unified serial number system, maintained by the Air Ministry (AM), and its successor the Ministry of Defence (MoD), is used for aircraft operated by the Royal Air Force (RAF), Fleet Air Arm (FAA) and Army Air Corps (AAC).
 Military aircraft operated by government agencies and civilian contractors (for example QinetiQ) are also assigned serials from this system.
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.
