If I managed an airline serving a pop of 2000 clinging to a rock in the eastern Atlantic spending most their time in the Divers I think I would sell off my aging aircraft, get rid of costly replacements and concentrate on routes that might get into profit, after all they can always go by Boat on Bumblebee.......ah might be a problem there! Get real, the airline is not responsible for the crumbling inadequate airstrip and you certainly couldn't afford IOS prices, for the limited traffic the service is vfm. Just do the costing of basing an air ambulance on island.
