I would gently remind everyone that no VC10 (or any other aeroplane) is "preserved" until it is permanently under cover.
The slow but deadly disintegration outdoors of the last surviving BOAC VC10s should serve as a reminder of this.
RAF Museum or not, Cosford seems unable to offer covered space for one in the forseeable future.
The last RAF VC10s might therefore be safer elsewhere in the long run.
