I thought I remembered this story saying the RC model had metal rotors, but it’s not mentioned in the link below. In any case:
The man, Roman Pirozek Jr. of Woodhaven, Queens, had been operating the large model — measuring several feet end to end — when it hit him and the top of his head was sliced off, the police said.
So these guys decide to fly their drone in the middle of a public street, near cars and pedestrians and they want sympathy when something goes wrong? Fly it in an empty lot or on a beach in the early morning, but don’t fly it around people or their stuff unless you want trouble.
