If Elon Musk bought the airport from ESKEN he would no doubt cut out the loss making parts of the airport leaving a runway, maintenance hangars and a few flying clubs. By doing that he could get rid of most of the fire cover and most of the staff. The terminal could be sold off to the likes of B&Q.
The sale price would not reflect how much ESKEN has spent, as they will be keen to just draw a line on ever increasing loses. The truth is I doubt they would not be brave enough to make big decisions.
