man at Magazine Beach Park in Cambridge, Mass., was
recently flying his Phantom FC40 quadcopter drone with a
camera attached and caught a video of a hawk attacking
the drone.
Christopher Schmidt, who was operating the drone,
reports the quadcopter and the hawk both came out of the
situation just fine. Aside from birds, bees have also been
known to attack these quadcopters. Birds can be killed by
quadcopters, so operators have to be careful how close
they fly to them.
