The Guardian:

The army has been called in to help with the ongoing crisis at Gatwick airport, where drones flying near the runway have kept planes grounded for over 12 hours.

The airport has been closed since Wednesday night, when the devices were repeatedly flown over the airfield in what police and the airport described as a deliberate attempt to disrupt flights.

Tens of thousands of travellers have been affected, with 110,000 passengers on 760 flights due to fly on Thursday. Eurocontrol said Gatwick would not re-open before 8pm at the earliest.

This is an issue that is only going to get worse as more and more consumer drones are used and get in the hands of idiots who fly unsafely.
