Jettison

To throw something off a ship, aircraft, or vehicle to lighten the load or get rid of it. It can also mean to abandon an idea, plan, or belief.

From Old French “getaison,” from Late Latin “jactatio,” meaning “a throwing,” from Latin “jactare,” “to throw.” It originally referred to cargo thrown overboard in emergencies. The meaning later expanded to dropping anything unnecessary, physically or metaphorically.
