What laws would I be breaking if I invented a death catapult funeral service in the UK?

I am thinking of starting a death catapult service in the uk for funerals. essentially pre death you sign up to be laoded (possibly naked) into a large catapult and flung into the sea. Your relatives are rpesent and there is a big screen showing your final jouney (you have a camera attached to your head).

You can choose music (Rocket man - Elton John, Its raining men - Various etc).

I am also considering (if the deceased opts in to the service) that people could shoot at you as you are flung out to sea.

Obviously we would weight the body so it sank when it hit the water - We don't want it washing back up on shore.

I have secured the url www.deathcatapult.com - I just need to know if it is legal.

Please indicate in your answers if you would consider using a service like this for you or your relatives.

from an ethical point of view i think this is a terrible idea - especially the idea ofp layign its raining men or rocketman - is that a joke? lol if not i laughed anyway - as for shootign at the body a definate no i do not think this is acceptabel under law let alone ethically!

one of the problem is people could start to go missing and searchign for bodies at sea would be pointless because of the amount of weighted down rotting ones already there from this funeral service, imagine the murders that could possibly covered up.

nto only this i cant iamgien anyone who would want this to happen once they die?

sorry but good luck!

Great Idea. I'd love to be a customer but I'll ask for a Trebuchet. I'll pay the premium.
