Two I can recall from Biggin Hill Air Fair days....
1964 May 09 G-ANHO Auster 5. Crashed on take off. Remember the a/c burst into flames. Seem to recall the pilot survived. Reading a report apparently there was one fatality.
1965 May 15 G-AROZ SV-4B Stampe Can't remember if the a/c was taking part in the display. Wreckage fell close to where the Auster had ended up the year previous. Again I think the pilot survived. Just been looking on the 'net, pilot was reported to be no less than Neil Williams !!
1996 Sept 01 G-BLTG WAR Replica Sea Fury. The a/c had attended the PFA Strut fly-in at Crossland Moor airfield near Huddersfield. The a/c crashed on take off. The pilot died of his injuries.
