Both of the higher time Black 6 pilots were unavailable for that last Duxford display slot, so, said high ranking officer, who was the 3rd pilot, flew the display, but hadn't done so for a while IIRC, which resulted in an incorrect human/mechanical interface issue occuring.......
GeeRam, well said, it was an absolute disgrace that this occurred and ended up with severe damage to this very unique aircraft.
I think the man was villified for this-rightly so.
