10 years ago I was in a PA28R off Catalina Island (West Coast USA, near L.A.) with a bloke whose Uncle had died recently. Uncle had requested he be scattered in the sea off Catalina, so we orbited at 5000 ft or so and one of the 4 of us on board cracked the door open 6 inches and threw the lot out in a plastic bag (a triple-layered arrangement - v. scientific)
There was no scattering, more of a splashdown. Not totally what Uncle wanted, but then you can't always get you want...
