He was also a pilot, but dissatisfied with the amount of real flight training that was available, he decided to build a ground-based device to provide such training without the restrictions of weather and the availability of aircraft and flight instructors.
His design had a pneumatic motion platform driven by inflatable bellows which provided pitch and roll cues.
Firing at a moving target requires aiming ahead of the target (which involves the so-called lead angle) to allow for the time the bullets require to reach the vicinity of the target.
This is sometimes also called "deflection shooting" and requires skill and practice.
During World War I, some ground-based simulators were developed to teach this skill to new pilots.
The best-known early flight simulation device was the Link Trainer, produced by Edwin Link in Binghamton, New York, USA, which he started building in 1927.
He later patented his design, which was first available for sale in 1929.
