Aircraft catapult
An aircraft catapult is a device used to allow aircraft to take off in a limited distance, typically from the deck of a vessel. They can also be installed on land-based runways, although this is rarely done. They are usually used on aircraft carriers as a form of assisted take off . In the form used on aircraft carriers the catapult consists of

The catapult officer carefully monitors the pressure level so it''s just right for the particular plane and deck conditions. If the pressure is too low, the plane won''t get moving fast enough to take off, and the catapult will throw it into the ocean. If there''s too much pressure, the sudden jerk could break the nose gear right off.
