In general, the vast majority of accidents that happen to ex-mil fast jets are during airshow (and probably by implication to the most experienced pilots).
I'm not sure about the pilot training requirements for such aircraft - particularly for somebody civil trained, maybe somebody in the room knows and can enlighten us?
By the way, I wasn't suggesting that things can't be improved - in fact I know CAA work quite hard to try and make warbird operation a lot safer than it is at present, I was mostly explaining why CAA aren't panicking about the current position.
