G-KEST, have you had a skim through the Vulcan, Metor and airshow incidents threads in the mil forum? Quite a few accidents/incidents recalled in those.
The RAF Harrier pilot killed at Yeovilton is correct, I'm just trying to recall his name. He forgot to re-pin the seat and trod on the handle as he was getting out, the display jet was from the OCU and I think that he was the display pilot following Hoof Proudfoot. Steve Something?
Actually, noting your location, you could nip over the road and ask.
