"It ISN'T cleared Aerobatics on its 2008 permit, hence it is breaching the regulations, do you think the CAA will turn a blind eye to that, I don't, especially post Shoreham..

IF the Vulcan actually competed a roll or any other maneuver considered "aerobatic", then the crew left CAA little option but to take enforcement action. The regulations for display are not so much the problem, as it is compliance to said regulations.
It is wonderful to see an airplane (oops aeroplane) like the Vulcan fly. Hopefully, this last flight does not give reason to deny future requests for demonstration flights other similarly loved and admired aircraft.
