... well, according to the BBC, here :
BBC NEWS | UK | England | Failed stunt 'caused air crash'
Ignoring the lack of licence, medical and maintenance (
) referred to in the BBC's report of the AAIB report (which I haven't read), the report doesn't clarify exactly what kind of "stunt" is supposed to have caused this loss of control and nose-dive ... 3-up in a Cherokee ???
RIP, anyway ...
