This huge metal arm can snatch drones right out of the sky

The U.S. Defense Advanced Research Projects Agency (DARPA) is working on a way to launch drones into flight and then snag them right out of the air with a system that can be loaded onto a truck or ship.   The agency recently released test footage of the next-gen drone tech, currently being developed under the callsign SideArm. It's designed to give the military the ability to manage the flight of large unmanned aerial systems (UASs, aka drones) from just about anywhere.   SEE ALSO: Mee
