Organizers of the 2018 Winter Olympics in South Korea have plenty to deal with, including the late addition of North Korea as a participant. But it’s not just events on the ground they have to worry about. Security personnel will be looking skyward, as well—for suspicious drones.

As part of safety precautions, drone-catching drones will be on hand to cast nets over any dangerous-looking unmanned aerial vehicles that approach the Olympics grounds in Pyeongchang. One fear is that an unauthorized drone could be used to deliver a bomb to disrupt the proceedings.
