There is, of course, a rather large well equipped RAF base about to lose its residents to Brize Norton - Bristol East/Swindon International coming soon?
Dedicated airspace already in place. Sitting right under an airway. 2 nice long runways. Hangars. etc etc. neatly placed close to M4 . Decent catchment area within 30 miles.
Just a thought. I'm sure MOL will be leafing through the airfield guides.
