Departures at Heathrow were temporarily stopped after a drone was reported to have been sighted.
Flights from the west London airport resumed about an hour after police said a drone had been seen. It comes after last month’s disruption at Gatwick Airport which saw thousands of people stranded when drones were sighted.
A Heathrow spokeswoman said Heathrow was working with Air Traffic Control and the Metropolitan Police following the incident. “We continue to monitor this situation and apologise to any passengers that were affected by this disruption,” she said.
The Metropolitan Police said they received reports of a drone sighting near Heathrow at about 17:05 GMT.
Before the confirmation that flights had resumed, Transport Secretary Chris Grayling said he was in contact with the airport about the drone sighting, and had spoken to the home secretary and defence secretary.
BBC cameraman Martin Roberts said he was driving on the M25 past Heathrow airport at about 17:45 GMT when he saw what he believes was a drone. “I could see, I’d say around 300 feet up, very bright, stationary flashing red and green lights, over the Harmondsworth area,” he said.
