FIVE people have been seriously hurt in a helicopter crash at an aerodrome, police have said.
Humberside Police were called to the scene at Breighton airport near Selby at 6.07pm on Sunday.
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 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."
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.
Meanwhile, a plane carrying new British foreign secretary Boris Johnson had to make an emergency landing on its way to Brussels.
The plane, described by the Ministry of Defence as a small military aircraft, had a "technical issue" after it took off from RAF Northolt on Sunday afternoon and had to land at Luton Airport.
A Foreign Office spokesman said: "There was a technical issue on the RAF flight on Sunday afternoon carrying the foreign secretary and his officials from London to Brussels that required the aircraft to land at Luton Airport.
"The foreign secretary thanked the RAF crew for their professionalism and was grateful to Luton Airport for the brief, unscheduled welcome.
"After a short delay the foreign secretary continued on his way to Brussels by alternative means."
This is the first flight and foreign trip Mr Johnson has been on since he was appointed foreign secretary last week.
