Well done on a splendid website.
The VC-10 was a magnificent aircraft. I well recall flying on the flightdeck of a 10 Squadron VC-10 from Brize Norton to Luqa (Malta) over 20 years ago.
The tragedy of the aircraft was that BOAC for political reasons damaged its sales prospects - this was probably done as part of the process of forcing the UK into the EEC. With a strong aircraft industry the UK would not have needed to join, particularly as export sales were in dollars.
After the collapse of the VC-10 programme we gave away our wing technology to Airbus, and the dismantling of our domestic aircraft industry was almost complete - thirty years after EEC entry Britain's civil aircraft industry, which once led the world, has been destroyed completely.
It is probable that EEC governments had an informal boycott of British airliners when we were still allowed to have an aircraft industry - all major EEC airlines were government controlled in the 1960s and none were permitted to buy any British aircraft after the Vickers Viscount.
