Dang! How on earth did you ever figure that one out, WHBM? Spot on!
Well, there aren't a lot of purchasers of the VC-10 to choose from !
Ghana Airways, and the country's government, were friends with everyone in the early 1960s. They got a couple of Bristol Britannias, new, followed by an extraordinary eight Ilyushin 18s, along with Antonov 12 freighters, which hardly got used apart from a weekly flight to Moscow, and all were returned to the Soviet Union two years later. From the US a pair of Rolls Royce-powered 707-463 were ordered, but then cancelled when the deposits were not forthcoming. Then a Convair 990 was obtained from Swissair, and then the order for three VC-10s, only two of which were actually delivered, and one of these was sold to MEA after a year. The sole remaining VC-10, however, then spent many years holding down the route to London on several days a week, and was a regular sight at Heathrow into the early 1980s, when it was finally replaced by a DC-10. I think it may have had the longest service into Heathrow of any of the VC-10s, few of which lasted in airline service more than 15 years.
