A 19-year-old’s remote control helicopter spiraled out of control and sliced open his head, killing him, at Calvert Vaux Park on Sept. 5.
Authorities said Roman Pirozek was flying the aircraft at the greenspace near the corner of Shore Parkway and Bay 44th Street at 3:40 pm when his model whirly-bird spun amok. The blades appear to have collided with the top of his skull.
Police report finding the young man unresponsive on the ground. Emergency medical personnel arrived moments later and pronounced him dead on the scene.
Pirozek was vice-president of the Brooklyn-based Seaview Rotary Wings, a club for model helicopter enthusiasts.
Cops said an investigation into the incident is underway.
