I agree the accident to the Hurricane at Wittering resulted in a few injuries to the pilot, but both he and the aircraft made a full recovery. I cannot recall any other major occurences to BBMF aircraft or crews but please correct me if I am wrong on this.
Fifty years of display flying vintage aircraft with only the rare engine problem is a real tribute, not only to the air and ground crews, but also to the original engineers who designed and built them.
If it's not an impeccable record it must come pretty close.
PS A real Merlin has three or four blades attached to it - not five.
