Tiger mate,
The Nimrod at Cosford went there on a truck. HQ 2 Gp would not countenance use of MOS to land a Nimrod (of either flavour) at Cosford - perfectly sensibly IMHO!
If it can be shown that the VC10 has the perfomance to safely land at Cosford then it may be flown there; if not, then it won't (I suspect). The runway at Cosford is very short (unless you are flying a Tutor)!
Regardless, I hope that the RAF Museum at Cosford gets a VC10 for display.
