The C2 at the De Havilland museum is a cockpit section used as a 4C simulator so the Lyneham one is the last C2 though there is a 1XB at Cosford which is probably why they don't want it. Seems a shame, & why don't they want a gate guardian for the Defence Training College?
Oh, I forgot, it will be 'brown-job' - led, so they'll probably have a tank or something to reflect the many years of aviation heritage of the site. I guess they can't wait to wipe out any trace of the 'Hundred year experiment'.
