I recall
Tony Hutton (died a few months ago), G-AZKI, now in US
Gary Numan, G-AZSC now flying from Goodwood
Peter Snell, G-BGOU, crashed at Bourn 1985 Snell killed
Norman Lees, G-BDAM, still in UK (Lees killed in Spit crash at Goodwood c2000)
Euan English, G-TEAC, crashed near North Weald c1995, English killed.
Probably others at various times. Sad isn't it, three died in flying accidents, only Mr Numan left...
