Unless it was an industrial-sized drone, I don&#x27;t see it doing much damage to a helicopter.  Helicopter blades carry an enormous amount of energy in them.<p>There are stories of Vietnam-era military pilots using the rotor&#x27;s blades to cut down small trees to rescue American soldiers in harrowing circumstances.<p>Regardless, all airborn vehicles should be able to transmit their location to other aircraft. Rather than forcing drone pilots to get FAA approval, this technology should be built into all drones. Bad actors will get culled out quickly and all non-transponding drones could be considered a threat.
