Agreat percentage the population chooses some type of scattering, burial at sea is the often selected method. Below are some notable people which have selected burial at sea.

Kennedy was one of the few presidential children to actually be raised in the White House. He was killed in a plane crash along with his wife and sister-in-law in mid-1999.

Steve Mcqueen (1930 - 1980)	An American movie actor nicknamed "The King of Cool."

He became the highest paid movie star in the world. He was an avid racer of both motorcycles and cars. While he studied acting, he supported himself partly by competing in weekend motorcycle races and bought his first motorcycle with his winnings.
