Regretfully I know of one which was written off.
I was operating the Odiham Approach position at Farnborough when a Beaver called asking clearance to operate in the Odiham section of Low Flying Area 1 (LFA 1b) I passed QNH and details of other traffic, and about 20 min later I had a phone call from Wallop Approach asking if I was still in contact. I called him and got no reply. Wallop informed me they had a report of a Beaver crashing on the side of the embankment near Dummer ('spaghetti junction' where the A30 and A303 diverge). Apparently they had been practicing 'touch and goes' in a small field and something had gone wrong, sadly both killed.
