Don't get me wrong, I'd love to see the Canberra returned to flight, and I agree, it is more important historically than the Vulcan and much more successful - in roles, export success etc. However the point being made here is that it may not be able to "impress" non enthusiasts in the same way the Vulcan could, or I suspect a Shack would. And by "impress" I mean, part with the money to fund it.
However I'm only speculating, it would be marvellous if both airframes could be restored to flight.
