Gaydon vs. Upper Heyford
Birmingham-Gaydon (William Shakespeare) International has a nice ring to it! It's on the M40, with a railway nearby. Airport staff could (at a push)transfer from Elmdon without having to move house. Upper Heyford is a bit too far out. However BHX is not operating at 99% capacity like LHR or 95% capacity like LGW, so there's no desperately urgent need for a second runway or a new airport.
