Well yes, FV, things built by Vickers do indeed seem to have a reasonable longevity! But since their other products are submarines and tanks, hardly surprising perhaps?
Regrettably corrosion and the age of materials used in construction will ultimately prove to be the end of the Vickers Funbus - not because of any inherent defect, but due to the unwillingness of the wretched bean counters and the ar$es at Wyton who are alleged to be the support organisation.......
My first airline trip was in a BEA Vanguard from London to Gibraltar (1963??); we also used to see a lot of the VC9 'Whispering Warehouse' at Brize when the Merchantman was bringing 'freight' here!
