A helicopter pilot giving rides at Pennsylvania's largest fair has died after walking into the aircraft's spinning rotor.
Organisers said Carl Enlow, 69, died after being hit by the rotor at the Bloomsburg Fair.
The fair's superintendent of police and parking, Bill Barratt, said the helicopter was refuelling when Mr Enlow went back to speak to the pilot who relieved him. Mr Enlow's hat blew off and he was struck by the rotor when he reached for it.
Mr Barratt said Mr Enlow, of Birdsboro, was an experienced pilot who had flown helicopters in the military.
Montour County coroner Scott Lynn said Mr Enlow's death was being investigated.
