Catapults and Taking Off from an Aircraft Carrier | HowStuffWorks

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.
