Being a professional pilot really isn't all that hard and other skills only add to the equation.Im sure as hell qualified to do a lot of other things and I do. Should I only fly because its my thing.
I know nothing of this situation or of the deceased, but Id bet my left nut, this bloke did it because he loved it, its what he'd always done, and would do over again given the opportunity. Just like the rest of us.
