Drones are amazingly useful flying machines that can snap pictures and video from impossible angles and that will likely deliver all sorts of things — your Amazon order, defibrillators, and who knows what else — before long. But in the wrong hands they can be a real problem. Short of shooting them out of the sky with traditional firearms there’s the DroneShield DroneGun. It’s completely safe for bystanders (except perhaps those directly underneath the drone) since it doesn’t actually fire any projectiles, instead jamming the drone’s controls and forcing the machine to land safely despite what it’s looks would have you think. Though for now it’s not available to the layman, and may remain quite difficult to get a hold of for non-governmental bodies. Which is perhaps a good thing if you own a drone since you won’t want just anybody hijacking your pricy flying camera.
