Genghis mentioned West Freugh as a possibility for a CPL school. Sadly the Freugh is now closed and on a care and maintenance only basis. However it was a significant local employer and the local council (Dumfries and Galloway Council) were actively looking at ways of keeping it open in some form or another and something like this may be of interest. It might be worth getting in touch with them.
I'm all in favour of it reopening as it would make visiting the mother in law more fun as I could fly there but dont let that affect your decision.
