"Motorsport UK, together with the event organiser and the local police, has begun a full investigation into the circumstances of the incident.

It comes days after several new Guinness World Records were set at the same airfield.
Andy Jennings, 28, set the record for the fastest speed ever in a wheelie bin, reaching speeds of over 40mph.
Andy, whose world record attempt was in memory of his best friend Ben Ellis, who passed away in June.
Ben had suffered an accident at work around five years ago, in which he broke his leg.
But he was left comatose for two years when a blood clot formed in his brain, and permanently disabled after he came round, unable to speak or move.
Andy set set the world record by reaching a speed of 43mph.
It was one of many land speed records broken at Elvington Airfield last Sunday (September 28).
Andy said: "Ben would have been proud of my achievement here today."
Racing down the runway as well as Andy was the world's fastest motorised toilet (44.6mph), and the world's fastest garden shed (at 106.1mph).
Elsewhere, Jason Liversidge, 44, reached speeds of almost 65mph in a motorised wheelchair - despite being 95 per cent paralysed.
The dad-of-two Jason was diagnosed with the degenerative Motor Neurone Disease in 2013.
But he has not let the illness hold him back - and since his diagnosis, has scaled Mount Snowdon in a wheelchair, and abseiled off the Humber Bridge in Hull.
