Drone Collision with helicopter = tail rotor failure
"During the Baja 500 while chasing from a helicopter a fellow race team was struck by drone. The helicopters tail rotor started to fail and with quick reactions the pilot was able to safely maneuver the helicopter to the ground without any injuries. Being that the helicopter couldn't fly now we had winch it on to a what normally is a car trailer"
