clicker,
I stand in awe of your experience ! When I was an RAF Adjutant of an Auxiliary Fighter Control Unit, they wouldn't even let me go down our "hole" (RAF Seaton Snook). Not special security cleared, old boy !
All right, give me a special clearance. Can't do that, old man, no need for you to know, you see. Less you know about our marvellous equipment, the better, that way you can't inadvertently betray any of our secrets to a Russian agent. (Ten years before, we'd sold a batch of Nene engines to our late gallant allies to cement our relationship). Sorry about this, old chap, but you do see how it is, don't you ?
From what you tell me, the Russkies could sleep easy in their beds !
Cheers, Danny.
