There is an article in "The Vulcan Story" which was written by SL David Thomas, last and future display pilot of XH558, in which he writes:
"It's interesting to note that towards the end of the Vulcan's display career, one show organizer simply stated that they would pay whatever the necessary asking price was, because they just had to have the Vulcan at their show. It's an incredible display aircraft, as it's a unique design, and XH558 is the only one of its kind. It flies very slowly, it's very manoeurvrable, it's big, it's noisy, quite unmistakeable."
Hopefully airshow audiences attitudes won't have changed that much, and the Vulcan will still be in great demand for airshows.
