I thought that HMP & Stalagluft Valley would be top for closure, but I'm slightly bemused that Coningsby gets a few mentions; it used to be fairly popular what happened?
As for me I'd move the Kinloss stuff to St Mawgan, Lossie to Honington, Leuchars to (Da! Da!) Tangmere and Valley to Chiv. The Bootnecks can blow up the wind farm as they leave. St Athan assets to Abingdon.
Akrotiri to be returned to H24 and have some AT, AD assets based.
Oh, and buy some more aircraft.
