G-KEST
May I offer these 'off the top of my head':
1952 - John Derry's DH110 broke up at the Farnborough airshow 1952 - 31 killed. UK' worst airshow disaster
1962 - Fg Off Blackgrove dived into the ground at RAF Khormaksar - Aden Forces Day, Hunter FGA9
1968 - Farnborough Airshow - Breguet Atlantic crashed into airfield hangar complex
1983 - Air Training Corps/Recruiting Event flypast at Scarborough c1984. RAF lightning crashed into the bay after loss of control in tight turn. I assisted the local police with beach clearance and recovery of the deceased pilot
1984 - Farborough Airshow - Bill Loverseed (ex Red Arrows leader) crashed, spectacularly, on the runway after a tight finals turn
1993 - Two Russian Mig 29s collided over the airfield - both pilots ejected and landed near the Red Arrows line. Both came into the BAe hospitality suite about 20 minutes later - calm as cucumbers.
1999 - Paris Airshow. Russian Su 30 failed to pull out after a 'spiral' manoeuvre - clipped his rear end on the airfield and ejected safely.
I witnessed the last five of these.
