Link Trainer
early flight simulator

The term Link Trainer, also known as the "Blue box" and "Pilot Trainer", is commonly used to refer to a series of flight simulators produced between the early 1930s and early 1950s by Link Aviation Devices, founded and headed by Ed Link, based on technology he pioneered in 1929 at his family's business in Binghamton, New York. During World War II, 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. Ed Link used his knowledge of pumps, valves and bellows gained at his father's Link Piano and Organ Company 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, New Zealand, United Kingdom, Israel, Japan, Pakistan, and the USSR. Following WWII, Air Marshal Robert Leckie (wartime RAF Chief of Staff) said "The Luftwaffe met its Waterloo on all the training fields of the free world where there was a battery of Link Trainers".
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 CAE USA Defense & Security CAE Inc., continues to make aerospace simulators.
History
Origins
Edwin Link had developed a passion for flying in his boyhood years, but was not able to afford the high cost of flying lessons. So, upon leaving school in 1927, he started developing a simulator. The project took him 18 months.
“Link Trainer” enters the record as early flight simulator. Crown Archives preserves that source wording while asking what Link, Trainer and early can confirm, complicate or overturn.
Why this record matters
“Link Trainer” is worth following because a concise public description often conceals a longer documentary argument. Here, Link, Trainer and early provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jan 29, 2026. The linked authority identifier is Q1781644. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1929 and 1927.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
