“As drones get cheaper to buy and easier to use, they’re also going to get more and more annoying. … For most people on the ground, there’s not a lot that we can do about an unwanted drone buzzing around overhead, especially if it’s out of shotgun range and you don’t have a military-grade laser handy. The solution to this is obvious and inevitable: intercept drones that seek out and bring down other drones.”
