Unrecoverable? You must be very inexperienced, as I've been only playing for a week and I know that isn't far enough to be unrecoverable. If you spawn on the western side of the map, suchh as cherno or any other western city from there, you can make it to the NW airfield in time to loot your corpse. You'll have to eat and drink the moment you get there, as running straight from the coast and to the airfield takes about 25-35mins depending on how well you can navigate there.
