Gatwick airport chaos exposes how much havoc drones can create

The disruption to hundreds of flights at London’s Gatwick airport after it was buzzed by miniature drones shows just how easy it can be to disrupt advanced aviation networks with simple, inexpensive devices. 

Airports have been raided by drones before. Dubai International was briefly closed in 2016, and Wellington, New Zealand’s main hub was shuttered for 30 minutes this year when a mystery craft was spotted close to the runway.
