ejection seat

airplane seat which can be automatically ejected from an aircraft in the event of an emergency

In (mostly military) aircraft, the ejection seat is a system designed to rescue the pilot or other crew in an emergency. In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it. The concept of an ejectable escape capsule has also been tried. Once clear of the aircraft, the ejection seat deploys a parachute, and descends safely to earth.
