The Chipmunk was written off whilst parked at Duxford during a display, an unfortunate victim of an aerobatic display going tragically wrong.
Ah I remember that - Hoof Proudfoot display pilot of great standing sadly died in a P38 Lightning while doing an aileron roll at fairly low level.
Took out a large number of visiting aircraft parked along the south side if I remember rightly.
