Gatwick airport: How countries counter the drone threat

Rogue drones "deliberately" flown over one of the UK's busiest airports caused travel chaos this week. Incoming planes were forced to divert to airports up and down the country as the drones, or unmanned aerial vehicles (UAVs), repeatedly appeared over the airfield at London's Gatwick Airport. The situation was so serious the Army was called in to support the local police in tackling the issue, with the runway finally re-opening on Friday morning. For some time now, governments around the world have been looking at different ways of addressing the dangers of drone use in areas where they pose safety risks. Here we look at some of the solutions - ranging from bazookas to eagles.
