The pilot declared the aircraft unservicable before shutting down and requesting some transport.
I did remark upon the unreliability of Vulcans in t'auld days, even given the massive support they enjoyed back then. For example there would be 22 aircraft out on the Waddington line (plus two in the shed) at any one time - including four bombed up and ready to go on QRA. There were two shifts with around eighty technicians each, struggling round the clock to keep the flying programme moving; this despite the fact that out of the available 18 or so aircraft there would always be half a dozen or more available to substitute for a grounded aircraft. Another couple of hundred techies in the sheds were doing relatively low level hangar maintenance in the shape of equalised Primary, Primary* and Minor checks - what the civil world would call A and C1/C2 checks. The proper heavy Minor* and Major checks were done at depots like Bitteswell.
In the present situation the JEngO would pick up the phone to SCAF and declare "VOG" and the parts would be hand delivered to the flight line within 24 hours maximum from wherever in the country they may be found - and that included manufacturers stocks. That level of support is no longer available, so we must expect a lot of last minute cancellations. Not the kind of service reputation that will get airshow organisers enthusiastic about paying for a Vulcan appearance - or not as the case may be.
