A man was left fighting for his life after a helicopter crashed in Buckinghamshire.
He was one of three men on board when it came down at Wycombe Air Park near High Wycombe on Friday morning.
Images of the wreckage show the helicopter resting on its side on an area of grass.
South Central Ambulance Service said one person suffered life-threatening injuries and another was being treated for serious leg, chest, abdominal, head and shoulder injuries.
The third patient suffered "less serious back injuries".
