I remember the first time one of the BAF Viscounts turned up at Leeds Bradford in 1982. It came on the radar frequency using the 'Victor Fox' callsign which I didn't recognise at the time. When it landed and taxied on to stand it never occurred to me that it was a former BA machine. It was painted all white apart from the blue lower fuselage so probably not long out of BA service. Not even any BAF lettering.
