the.com/ejection seat

means A rocket-propelled seat that blasts a pilot clear of a disabled aircraft so their parachute can open before the plane does not.

from From 'eject' (Latin eicere, 'to throw out,' from ex- 'out' + iacere 'to throw' — the same root that gives us 'projectile'), paired with 'seat' simply because that's the part the pilot sits in. The device itself is a 20th-century invention, born alongside high-speed military jets, when planes started flying too fast for a pilot to just climb out and jump — the seat had to do the throwing.
