fanjet - the Shropshire Star carried numerous articles about 6 months ago which outline plans to make Cosford available for Bizjet use. At the time the issue was getting planning permission from Wrekin county council or some such.
As I recall permission was eventually granted. Don't know who or what was behind the plans but it does look doable. The runway is suitable and there is both apron and hangar space kicking around. As has been pointed out the location has excellent motorway and rail links and also a good deal of inherent security which is becoming important.
