We parked fifty yards away from a helipad, where fairgoers could pay $60 for a trip above Lancaster in this chopper. It seemed airworthy enough, but helicopters above crowds make me nervous. Just as we were getting out to walk into the fair, it took off and came our way. I fumbled with my iPhone and somehow managed to get two frames as the helicopter flew over my head. I like how a tiny camera thinner than a couple of credit cards can freeze two helicopter rotors.
