So all you need now is a player with many millions of cash going spare and willing to spend it with no guarantee of seeing a return on investment, probably ever.
You need to get the place a CAA Aerodrome Licence (by no means easy)
You need full aerodrome lighting for night ops.
You need instrument approaches (precision like ILS, not GPS)
You need licenced ATC and enough controllers to staff the place.
You need to upgrade fire cover to a much higher level.
You will need far greater fuel storage facilities.
Oh and a decent VIP terminal. The 'Squadron' will not make the grade, or their dodgy lavatories.
If it was a good business plan someone would have done it by now.
