A stunt wing walker has died after falling about 60 metres as horrified crowds looked on at an air show in the state of Michigan.
A spokesman at Selfridge Air National Guard Base said the wing walker, Todd Green, was trying to move from a biplane to a helicopter on Sunday in a complicated manoeuvre when he fell at the base, 20 miles north-east of Detroit.
Technical Sergeant Dan Heaton said an ambulance rushed Mr Green to a nearby hospital, but he died from his injuries.
Mr Green waved to the crowd from the wings of the biplane moments before he plunged to his death. AP
