Look Spath, please go and research search and rescue techniques. You clearly are very naive on the subject if you think you will find a dead body in the sea from a helicopter.
And helicopters are dangerous over sea in the winter too you know. Most likely what bought this plane down was ice. Helicopters can suffer badly in icy conditions. so same applies. You want to risk the lives of others to find a corpse.
Perhaps this draws comparisons with the search operation currently going on in Spain for Julen in the bore hole. He has been gone 12 days with no food/water and probably no oxygen, yet they are still battling to reach him. Goodness knows the cost of it all.
In the case of the Spanish boy, whether or not he is dead I am sure that his family will want to recover the body for a proper burial. And if he is alive after all, against all odds, then not a penny will have been wasted.
