A Berks County man was killed in a freak accident at the Bloomsburg Fair in Columbia County, officials said.

Carl Enlow, a helicopter pilot from Birdsboro, died Friday after walking into the aircraft's spinning rotor while giving rides at the fair, officials said.

The helicopter was refueling when Enlow, 69, went back to speak to the pilot who relieved him, officials said.

Enlow's hat blew off his head, and he was struck by the rotor when he reached to get it, officials said.

Enlow was an experienced pilot who flew helicopters in the military, officials said.
