Context: The aerospace industry of the United Kingdom is the fourth-largest national aerospace industry in the world and the third largest in Europe, with a global market share of 6.4% in 2016.  In 2013, the industry employed 84,000 people.  Domestic companies with a large presence in the British aerospace industry include BAE Systems (the world's third-largest defence contractor), Britten-Norman, Cobham, GKN, Hybrid Air Vehicles, Meggitt, QinetiQ, Rolls Royce (the world's second-largest maker of defence aero engines) and Ultra Electronics.  Foreign companies with a major presence include Boeing, Bombardier, Airbus (including its Astrium, Cassidian and Surrey Satellite Technology subsidiaries), Leonardo (including its AgustaWestland and Selex ES subsidiaries), General Electric (including its GE Aviation Systems subsidiary), Lockheed Martin, MBDA (37.5% owned by BAE Systems), Safran (including its Messier-Dowty and Turbomeca subsidiaries) and Thales Group (including its UK-based Thales Air Defence, Thales Avionics and Thales Optronics subsidiaries).  Current manned aircraft in which the British aerospace industry has a major role include the AgustaWestland AW101, AgustaWestland AW159, Airbus A320 family, Airbus A330, Airbus A340, Airbus A380, Airbus A400M, BAE Hawk, Boeing 767, Boeing 777, Boeing 787, Bombardier CRJ700, Bombardier CSeries, Bombardier Learjet 85, Britten-Norman Defender, Britten-Norman Islander, Eurofighter Typhoon, Hawker 800, Lockheed Martin C-130J Super Hercules and Lockheed Martin F-35 Lightning II.  Current unmanned aerial vehicles in which the British aerospace industry has a major role include BAE Taranis, HAV 304 Airlander 10, QinetiQ Zephyr and Watchkeeper WK450. Lao Airlines Flight 301 was a scheduled domestic passenger flight from Vientiane to Pakse, Laos.  On 16 October 2013, the ATR 72–600 aircraft operating the flight crashed into the Mekong River in Pakse, killing all 49 people on board.  The accident, the first involving an ATR 72–600, was the deadliest ever to occur on Laotian soil and the third-deadliest involving an ATR 72 behind Aero Caribbean Flight 883 and American Eagle Flight 4184, which both killed 68.  It was also the first fatal accident for Lao Airlines since 2000.  The investigation report suggests pilot error as the probable cause.  The accident was the second-deadliest aviation incident in 2013, behind Tatarstan Airlines Flight 363. ATR (Aerei da Trasporto Regionale or Avions de transport régional; "Regional Air Transport" in English) is a Franco-Italian aircraft manufacturer headquartered on the grounds of Toulouse Blagnac International Airport in Blagnac, France.  It was formed in 1981 by Aérospatiale of France (now Airbus) and Aeritalia (now Leonardo) of Italy.  Its primary products are the ATR 42 and ATR 72 aircraft.  ATR has sold more than 1,500 aircraft and has over 200 operators in more than 100 countries. The ATR 72 is a twin-engine turboprop, short-haul regional airliner developed and produced in France and Italy by aircraft manufacturer ATR (Aerei da Trasporto Regionale or Avions de transport régional), a joint venture formed by French aerospace company Aérospatiale (now Airbus) and Italian aviation conglomerate Aeritalia (now Leonardo S.p.A.).  The number "72" in its name is derived from the aircraft's standard seating configuration in a passenger-carrying configuration, which could seat 72-78 passengers in a single-class arrangement. Avro International Aerospace was a British aircraft manufacturer formed in 1993 by British Aerospace to consolidate production of the British Aerospace 146 at Woodford Aerodrome near Manchester.  The company produced new variants of the 146 with updated engines and avionics as the Avro RJ70, Avro RJ85 and Avro RJ100 regional jets. The British Aerospace Jetstream 41 is a turboprop-powered feederliner and regional airliner, designed by British Aerospace as a "stretched" version of the popular Jetstream 31.  Intended to compete directly with 30-seat aircraft like the Embraer Brasilia, Dornier 328 and Saab 340, the new design eventually accommodated 29 passengers in a two-by-one arrangement like the Jetstream 31.  Eastern Airways of the UK is the biggest operator of Jetstream 41s in the world, with 17 in the fleet. The British Aerospace 146 (also BAe 146) is a short-haul airliner and a regional airliner that was manufactured in the United Kingdom by British Aerospace, later part of BAE Systems.  Production ran from 1983 until 2002.  Manufacture of an improved version known as the Avro RJ began in 1992.  A further-improved version with new engines, the Avro RJX, was announced in 1997, but only two prototypes and one production aircraft were built before production ceased in 2001.  With 387 aircraft produced, the Avro RJ/BAe 146 is the most successful British civil jet airliner programme. The Beechcraft 1900 is a 19-passenger, pressurized twin-engine turboprop fixed-wing aircraft that was manufactured by Beechcraft.  It was designed, and is primarily used, as a regional airliner.  It is also used as a freight aircraft and corporate transport, and by several governmental and military organisations.  With customers favoring larger regional jets, Raytheon ended production in October 2002. The British Aerospace ATP (Advanced Turbo-Prop) is an airliner produced by British Aerospace, introduced in the 1980s as an evolution of the Hawker Siddeley HS 748.  The fuel crisis and increasing worries about aircraft noise led business planners at British Aerospace to believe that there was a market for a short-range, low-noise, fuel-efficient turboprop aircraft.  By the time it entered the market, the segment was already well represented by designs such as the de Havilland Canada Dash 8, ATR 42 and ATR 72 and production was ended after only 64 examples. The ATR 42 is a twin-turboprop, short-haul regional airliner developed and manufactured in France and Italy by ATR (Aerei da Trasporto Regionale or Avions de transport régional), a joint venture formed by French aerospace company Aérospatiale (now Airbus) and Italian aviation conglomerate Aeritalia (now Leonardo S.p.A.).  The number "42" in its name is derived from the aircraft's standard seating configuration in a passenger-carrying configuration, which typically varies between 40 and 52 passengers.
