Chaos at Gatwick as drones ground flights - @StephenNolan talks to travel expert @SimonCalder

Huge disruption at one of the UK's busiest airports this morning after drones were spotted over the Gatwick. The runway shutdown started just after 9pm last night, when two drones were spotted being flown over the airfield. The runway was briefly reopened at about 03:01, but forced to close again about 45 minutes later amid "a further sighting of drones". Chris Woodroofe, the airport's chief operating officer, told the BBC about 2,000 flights had been unable to take off - affecting 10,000 passengers. The airport said police were still hunting for the drone operator after another device was seen nearby just before 7am. Stephen spoke to travel expert Simon Calder.
