I flew on BBVH in my younger years and I vaugly remember the landing @ GIB.
I worked with a chap a few years back who was involved with removing parts from the airframe at Tangiers. He told me it was moved to the edge of the airfield and left there.
I have been unable to find out what happened to it after that and a quick look on Google Earth reveals nothing that resembles at Viscount (that I can see).
