Tens of thousands of passengers at one of the UK's busiest airports are experiencing flight disruption after drones were seen over the airfield.
Gatwick's runway remains closed after two of the devices were seen nearby.
Flights are unable to take off or land and Gatwick said 110,000 passengers on 760 flights were due to use the airport on Thursday.
Police were still hunting for the drone operator after another device was reported just before 07:00 GMT.
A spokesman for Sussex Police said: “There is absolutely nothing to suggest that this is terrorism-related.”
Gatwick chief operating officer Chris Woodroofe said police had not wanted to shoot the devices down because of the risk from stray bullets.
