Not an airshow but, as I recall, Spencer Flack's Sea Fury was destroyed ploughing up spuds just short of the road when he tried for an emergency landing on 20/21 at Waddington - the engine had misbehaved en route from somewhere to somewhere.
Having watched a Ju52 mainwheel pass me by at head height and little more than a wingspan away while standing by the airfield fence on the common at Blackbushe many years ago, I would never stand under an approach close to threshold.
