Luis María Mendía's Airplane

Origin
Luis María Mendía was the Argentine Chief of Naval Operations in 1976-77, with the rank of vice-admiral. According to confessions, Mendía was the architect of the "death flight" assassination method whereby the Argentine state disappeared people by throwing them out of aircraft over the ocean, thus making the retrieval of their corpses nearly impossible (and thus subsequent legal investigations unlikely).

Effects
The plane will eject out the passengers when flown over a large body of water in an attempt to kill them, whether by the explosive decompression of the plane’s pressurized environment or by the impact with the surface. Any evidence and the body are usually highly damaged, making the person who ordered the assassination untraceable.
