There are two sides to every story - so before we start attacking the airport:
1) The owner has had a stroke, the school has been run by his wife since. If the will to continue the business was there, why not re-locate to another airfield?
And where would you relocate to ChilliMonster? Most of the GA fields about are probably owned by the same people owning the schools... I am sure they would just LOVE the competition, as would the schools there..
Also simply upping sticks and bogging off at a moments notice is not really a practability....well unless your name is R***A*R.... their track record on this isn't exactly startling compared to a company that has been established on the same site for over 20 years, One hopes it does not come home and bite the airport on the butt having seemingly laid all their eggs in one proverbial basket.
4) Unlike areas like Newcastle, Belfast etc the area is well served by 3, licenced, GA airfields.
If that was the case, then why did the school have over 300 members? surely they would have gone elsewhere if the supply was adequate.
