An airdrop is a type of airlift in which items including weapons, equipment, humanitarian aid or leaflets are delivered by military or civilian aircraft without their landing. Developed during World War II to resupply otherwise inaccessible troops, themselves often airborne forces, airdrops can also refer to the airborne assault itself.
