The capabilities of drones seem to be expanding every day. Recently, researchers in Slovenia have tested drones as part of rescue teams. One of their recent proof of concept videos uses a drone to drop a rope to a man stuck in a frozen lake. The rescue team can then pull the man to shore with the other end of the rope.
However, with expanding capabilities also comes additional oversight. People in the Netherlands are testing the use of raptor hawks as anti-drone tools. The hawks are trained to take down drones in unauthorized areas; if used, the hawks will likely be fitted with leg guards to protect them from propellors.
