The term Link Trainer, also known as the "Blue box" and "Pilot Trainer"〔Kelly 1970, p. 33.〕 is commonly used to refer to a series of flight simulators produced between the early 1930s and early 1950s by the Link Aviation Devices, Inc, founded and headed by Ed Link, based on technology he pioneered in 1929 at his family's business in Binghamton, New York. These simulators became famous during World War II, when they were used as a key pilot training aid by almost every combatant nation. The original Link Trainer was created in 1929 out of the need for a safe way to teach new pilots how to fly by instruments. A former organ and nickelodeon builder, Link used his knowledge of pumps, valves and bellows to create a flight simulator that responded to the pilot's controls and gave an accurate reading on the included instruments. More than 500,000 US pilots were trained on Link simulators,〔 as were pilots of nations as diverse as Australia, Canada, Germany, United Kingdom, Israel, Japan, Pakistan, and the USSR. The Link Flight Trainer has been designated as a ''Historic Mechanical Engineering Landmark'' by the American Society of Mechanical Engineers. The Link Company, now the Link Simulation & Training division of L-3 Communications, continues to make aerospace simulators.〔("Link Company." ) ''link.com''.

So, upon leaving school in 1927, he started developing a simulator, an exercise which took him 18 months. His first pilot trainer, which debuted in 1929, resembled a toy airplane from the outside, with short wooden wings and fuselage mounted on a universal joint. Organ bellows from the Link organ factory, the business his family owned and operated in Binghamton, New York, driven by an electric pump, made the trainer pitch and roll as the pilot worked the controls.〔("U.S. Air Force Fact Sheet: Link Trainer." ) ''National Museum of the United States Air Force''. Retrieved: 20 February 2010.〕 Link's first military sales came as a result of the Air Mail scandal, when the Army Air Corps took over carriage of U.S. Air Mail. Twelve pilots were killed in a 78-day period due to their unfamiliarity with Instrument Flying Conditions. The large scale loss of life prompted the Air Corps to look at a number of solutions, including Link's pilot trainer. The Air Corps was given a stark demonstration of the potential of instrument training when, in 1934, Link flew in to a meeting in conditions of fog that the Air Corps evaluation team regarded as unflyable.〔 As a result, the Air Corps ordered the first six pilot trainers at $3,500 each. The Link company expanded rapidly, and during World War II, the ANT-18 Basic Instrument Trainer, known to tens of thousands of fledgling pilots as the "Blue Box" (although it was painted in colors other than blue in other countries), was standard equipment at every air training school in the United States and Allied nations. During the war years, Link produced over 10,000 Blue Boxes, turning one out every 45 minutes.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Link Trainer」の詳細全文を読む スポンサード リンク
