You'r dammed if you do and dammed if you don't on this one G!
There are two options realy, throw so many modifications at him he will get board with it or run out of money. Or place so many resrictions on the beast that he will, again get board with it.
What are his chances of killing himself in it?.
I think that the C.A.A. have got the balence right with vintage aircraft, I know that's not everyone's view but having read B.C.A.R. A8-20 I feel "comfortable" with thier decisions. I would love to see a Vulcan, Victor, Lightning and Bucc fly again but only safely with the right engineering/operational organization behind them.
Do keep us informed,If you can
