Surely someone at ETPS knows how to establish who owns a civil registered aircraft? Or haven't they even heard of G-INFO?
Any how, whichever military person runs ETPS these days (assuming there is someone) should have told KwintyKwoo that the lousy piece of Commie crap was unfit for purpose, get rid of it and pursue the sub-sub-sub-sub contractors for frustration of contract whilst finding another more suitable aircraft.
Diplomatic Service? That would have meant dealing with cocktail party civil serpents and their brown envelope contacts, so no thanks!
