Let's get this straight......long before Flybe, Capital and Air UK good old BKS Air Transport operated the Yeadon to Aldergrove route in the late 50s with Dakotas and subsequently AV748S! Of course they were followed by British Air Services, Northeast Airlines and eventually British Airways all with Viscounts. Those were the days and without even Cat 1 ILS at LBA diversions were more common than arrivals!
