Presumably you have some feedback from the CAA that they would be happy for a Jaguar to fly on a Permit. I was told that they are unlikely to allow anything more complex than a Hunter. It also assumes that the current Design Authority is happy to continue once the military stop flying it. I know that this was a problem with the Sea Vixen which, I believe, was solved by FRA. Presumably BAe have agreed to maintain responsibilty for the Vulcan, should it ever fly again.
Anyway, best of luck. I have always liked the Jaguar and would be pleased to see it continue.
