Drone-catching drones armed with nets hit Winter Olympics

South Korea is deploying a fleet of drone-catching drones to bolster security at this month's 2018 Winter Olympics. Police will use the drones to drop nets on dangerous-looking unmanned aerial vehicles approaching the Olympics grounds in Pyeongchang. The Games, which start Friday, are expected to draw 35,000 spectators, with a host of world leaders including US Vice President Mike Pence set to attend. Officials are concerned that terrorists could use rogue flying machines to disrupt the two-week event by carrying bombs toward crowd members or athletes.
