It's a very sad business. It was barely plausible that the Nimrod wasn't able to fly in to Cosford but the VC10 is just absurd, especially when it's already been done quite easily before.
But it raises a question over the RAF Museum's position. If this issue is going to affect the aircraft types that are preserved then where will it end? Will future exhibits be turned down in this fashion, just because Cosford's runway is perceived as being too short? What kind of logic is this for a nationally-important museum?
