Sailor Speak of the Week – Jettison



  • To throw cargo, stores, or gear overboard.


Derived from the noun jetsam.


A fairly common word nowadays. Used in both the maritime and aviation fields. Sailors/ships can jettison cargo or gear and aircraft can, as well. (e.g. a combat aircraft jettisoning external fuel tanks when empty.)
