Services at Gatwick Airport are back to normal after the airport had suspended all flights.
Gatwick apologised to passengers at the UK’s second busiest airport, where flights were grounded just seven months ago after drones were reported flying in the airspace.
But after around three hours of disruption, the airport released a statement that flights are back to normal.
The airport said: "Following an earlier air traffic control systems issue, flights to and from Gatwick have now resumed.
"If you are travelling this evening please check the status of your flight with your airline before travelling to the airport, as we return to full operations."
Flights had been suspended after an issue with air traffic control systems in Gatwick's control tower.
ITV News Consumer Editor Chris Choi tweeted that the latest mass disruption at Gatwick is a "big blow" for the airport.
He said: "Another big blow for #Gatwick after December’s drone chaos cost £1.4m - now it could face massive financial claims for tonight’s disruption."
