But the introduction of the 767 and relaxation of ETOPS rules in the 1980s pretty much pulled the rug out from under Vickers.I think the rot set in back in the '60s when BAC stole a march on the double-deck aircraft market by building the double-deck VC10 'Superb'. Since BOAC, Quantas and TCA were already using the Standard and Super VC10 it was a natural extension for them to buy the Superb. Didn't exactly help that Pan Am had already decided it preferred the Super 200 over more 707s.
OOC: I don't think the Superb would be that much of a match for the 747, given its specs.
