Facinating! That thing could fly so fast, it would start to melt! I refueled one of these in West Germany, although the Americans will deny it was ever there. It was on it's way back to England after bombing Libya in 1986. Most of the European countries had denied overflight for the mission, so they had to take a very long roundabout route to get to their target. The Americans did a rehearsal for this mission in Goose Bay. More info here:
