Ответ:
Christopher Cockerel's idea was to build a vehicle that would travel just above the surface of land or water. His invention started with two cans, one inside the other, and a hairdryer to blow air into them. The experiment showed that air could produce enough pressure to lift a vehicle off the ground.
In 1959 in the English Channel, Christopher Cockerel presented the first hovercraft which has been used throughout the world ever since for commercial and military reasons.
