That's an utter myth
Wow, it's a pretty well-entertained myth then. The local MP is demanding to know how the MoD will meet its obligations to the Rothschilds. Sounds like any future developer would be free to demolish the place and lay a car park over it.
In the bright new world of OJEU'd MFTS, other than the obvious reasons of wanting your future military pilots to have some experience of actually being in the military, what would prevent initial MFT being carried out at Civvy airfields - such as Cranfield?
