For the USA the situation is so “serious” that a law recently approved imposed registration of all new drones purchased in the United States to locate them in case of an accident. The need to formalize this law would be found in a security problem. One of the most sensational came when a drone flew at extremely close distances to an airliner with 159 people on board. Also from US soil came recent reports of a drone that has hampered the operations of firefighters during the fire fighting training. Drone that was on site to resume its fire without authorization. A real problem especially for emergency helicopters were flying low over those areas.
