Linton is doomed as it is one of the few airfields the RAF have left that can actually be closed. Many of the others have covenants that require them to be returned to the original owner in the state that they were in when first occupied. Removing bomb dumps that glow in the dark and HAS sites is awfully expensive - the MOD is broke and can't afford to. LOZ will be relatively cheap to close.
As for putting Tincans in VYL, the mixed circuit is going to be dangerous. Yes, VLN may cope with a gazzillion aircraft but they aren't flown by a student who has very few flying hours and is maxxed out just trying to fly S&L, let alone having to cope with a fast jet 4 ship breaking into the circuit and a 80 kt helo flying a PAR into a 30 kt headwind!!!! Throw in the Sea Kings (203 Sqn) that are now going to be around for a while longer and the situation becomes untenable. VYL does have an RLG at Mona but the Sea Kings block book that for half a day at a time, denying its use to fixed wing. If the Tincans are to be placed at VYL, the Sea Kings have to go - 3 completely disparate training types cannot be mixed at one location.
As for VYL closing, dream on. With the closure of most of the major employers on Anglesey, the RAF is the last one left. Politically, its closure will be unacceptable, sigh.......
