I think you will find that he is nor "legally" dead until declared so by a doctor so this normally happens after landing.
If thats the case and there is a Doctor on Board a medical flight or airline flight are they asked to delay declaring a death until after landing?
Does this happen with the airlines where a Doctor may be going on business or Holiday and attends a heart attack victim? Ie if this death happens mid flight, the Doctor tries to save him but then declares him dead where has he actually died?
