"Drones can cause serious injuries if not operated properly. Last year, a Brooklyn man was killed when his own drone hit him in the head. Other incidents have been close calls, including a drone in Manhattan falling hundreds of feet and landing at the feet of pedestrians on the sidewalk below, and a wedding photographer’s droneaccidentally flying into a groom who was posing for romantic images with his bride-to-be. Recently, we have seen news reports of drones flying too close to airports and in the paths of helicopters. And, it’s not hard to imagine the safety concerns that arise from many drones flying through the sky — something like a three-dimensional highway system with no roads, no traffic lights, and no drivers in the cars. Those same concerns might have implications for safety on the ground: just think of drones flocking to catch a glimpse of medical emergencies, forest fires, or a presidential motorcade."
