Five people have been seriously hurt in a helicopter crash at an aerodrome, police said.
Humberside Police were called to the scene at Breighton airport near Selby at 6.07pm.
A force spokesman said the injuries are serious but are not believed to be life-threatening.
Two people were taken by air ambulance to Hull Royal Infirmary and Leeds General Hospital, while three others were driven to hospital.
The casualties were all male and had suffered various head, back, chest and leg injuries.
North Yorkshire Fire Service said all of them were out of the helicopter when rescuers arrived.
The Yorkshire Air Ambulance Service said both its helicopters were sent to the crash site.
Breighton Aerodome is a former Second World War heavy bomber base and cold-war nuclear missile launch site.
It is now the home of the Real Aeroplane Company, a collection of classic planes, and the Real Aeroplane Club, whose members own and operate many unusual aircraft.
The wreckage of the crashed helicopter, said to have come down on grass at the side of the runway, has been taken away.
The force spokesman said: “Numerous emergency services were in attendance.
“The Air Accidents Investigation Branch (AAIB) will be leading the investigation to establish what caused the crash.”
