The rapid air start system was the very devil to maintain and not many Vulcans had both port and stbd systems servicable at the same time. The system also required a very large amount of compressed air at 6000 psi. I'm sure that somebody would be able to provide a suitable supply of air but at what cost? Then there's the problem of getting the compressed air to the display venue!! It would be nice to see a "ripple rapid" start again but somehow I don't think it will happen.
