The operator of a drone that

collided

with a U.S. Army Black Hawk helicopter in September didn’t see the aircraft because he was flying the drone beyond visual range, the NTSB said on Thursday. The operator also lacked adequate knowledge of the regulations and safe operating practices for drone flying, the safety board

said

. The incident occurred in New York, at an altitude of about 300 feet. The helicopter crew landed safely. Parts of the drone were lodged in the helicopter’s engine-oil cooler fan, and a 1.5-inch dent was found on the leading edge of one of the four main rotor blades. The drone operator was flying for fun, the NTSB said, and was unaware of the TFR in place at the time. He did not hold an FAA remote pilot certificate. Also this week, the FAA’s rule requiring owners to register small drones was reinstated.

Another case that will result in more restrictions.

Yes unfortunately! Drone pilots have to be more careful.

Hi, guys. I would recommend users read carefully about the FAA regulations and fly with caution.

And the report is clearly also stating, that using the RTH function without need to get a drone home is not the best idea!
It is a failsafe feature, not a comforting one! In my eyes.
I would assume, even ~2 miles out, if the pilot would have 'watched' the drone, piloting it back 'with one eye on the display' and checking on the area where it is coming from,  'with the other eye' , he would have had a chance to see and react on a helicopter coming it's way! At least descending would have been an option.
Aside that he should have known, that he did fly in a temporary no fly zone. Best not to fly that time!
