"Ohhh, I'll be gorrammed. That's where that cash went. I stole that money from Higgins just like the song says, lifted me one of his hovercraft. But I got tagged by anti-aircraft, started losing altitude. Had dump them strongboxes to stay airborne. Oh... 60,000, untraceable. And I drop it right square in the middle of mud-farmer central."Gravity Sucks, especially when you are on an aircraft or balloon and face engine failure. What can you do to prevent or at least delay a crash landing? Right, you jettison your cargo. Emergency Cargo Dump describes incidents where characters throw objects away to decrease weight or decrease ballast. This may be to prevent a faltering plane from crashing or a leaky boat from sinking. It may also be to gain speed, if the characters are in The Big Race, or trying to outrace an enemy that is in Hot Pursuit. This last example could even include persons on foot who jettison the things they are carrying. An occasional variation has cargo dumped to prevent some other kind of trouble (perhaps you're carrying hazardous cargo that's threatening to explode, or you're carrying contraband and the authorities are closing in to search your vessel). Cargo deliberately thrown from a moving vehicle is called "jetsam", and is legally distinct from "flotsam", which is floating wreckage from a crashed plane or sinking ship. See Cold Equation for similar situations where a human sacrifice is required. See Disposable Vehicle Section for cases where part of the vehicle itself is ejected. Bring My Brown Pants is a biological response to stress designed to lighten a body's load/cause a distraction for a quick getaway. Completely unrelated to Dramatic Drop.

Finally, Kramer still feels they're too heavy, so he manages to kick Newman out of the truck and press on; then, he gains speed.
- The Doors track Horse Latitudes was inspired by Jim Morrison reading about historical cases of cargo-dumping. specifically, Spanish ships caught in the windless Doldrums and becalmed for long periods. Unable to move and fast running out of drinkable water, if they were carrying live cargo this would be jettisoned. Morrison was moved at the horses so dumped, so as to ease pressure on limited resources.

Fortunately, they manage to get back home when Goofy's experimental cleaning solution gets into the fuel tank.
- Parodied in Secret Squirrel where Secret has a car race with Hot Rodney. Secret's passenger Morocco Mole tries to speed them up by throwing everything out. Then he removes the chassis, then the seats, then the engine, which of course, causes them to lose.
- Airplanes that have to make an emergency landing often dump fuel to lighten the load (the weight differential between full and empty tanks is a factor in landing) and/or reduce risk of fire.
- Common in Real Life in World War II.
- Bombers over Germany, if hit or crippled, routinely threw out everything they could to lighten the load and make it easier for a plane under reduced power to return home. Surplus equipment, ripped-up internal fittings, anything that would make the load lighter. In one case, a damaged gun turret too shot-up to be used was hacked away and allowed to fall (the wounded gunner was carried home, though).
- Australian night bombers routinely emptied their on-board chemical toilets over German targets, claiming they were reducing load for the return flight. Nazi Germany complained under the Hague Convention that the British were using illegal chemical weapons. The complaint was upheld!
- Ships typically carry a supply of weight known as a Ballast, used to help maintain the ship's balance and draft in the water with varying loads of cargo and fuel. For ocean-going ships, this is typically seawater (since it is plentifully available), for airships and balloons, sandbags and other solid weights might be used instead to help control altitude. In an emergency, an airship could release their ballast to lighten the weight and slow their descent.
- A Submarine, meanwhile, uses ballast as it's primary depth control, and can either release it or intake it slowly to gradually ascend and descend, or quickly in order to sprint to the surface (known as an "Emergency Blow") or to dive away from danger (known as a "Crash Dive"). These emergency maneuvers can themselves be dangerous due to A) Being about as stealthy as dropping a ship into the ocean, that is, not very, and B) the risk of the sub crashing into something unseen (as has happened in the past). Further, if the sub's hatches are not properly secured, a sudden crash dive could quickly turn into an unplanned scuttling.
- Some birds such as vultures will regurgitate the contents of their filled crops, if the weight of a heavy meal would otherwise be too great for them to get airborne and escape an oncoming predator.
- The Lady Be Good, a USAAF B-24 Liberator, crashed in central Libya on a bombing run after overflying its base due to a sandstorm. Several pieces were recovered between 1960 and 1963 and used in USAF aircraft, such as the autosyn transmitters, put in a C-54 Skymaster which had to jettison cargo to land safely due to propellor difficulties.
- A chilling version of this trope was the Zong Massacre, where a slave ship that was running out of water decided to throw 133 African slaves overboard. The slaves would have died anyway of thirst (however a rainstorm that occured afterwards replenished much of their supply), but a loophole in insurance law allowed the crew to be compensated in full for any 'cargo' that had to be dumped over the side to save the ship.
