The United Kingdom’s second-biggest airport has been closed for more than 19 hours in unprecedented disruption caused by drone sightings, which police have described as a “deliberate act.”
London’s Gatwick Airport has been closed since 9 p.m. on Wednesday — bar a brief reprieve of 45 minutes early Thursday morning — after drones were spotted near the airfield.
As of Thursday afternoon, police were still on the hunt for the drone operators who have brought the airport to a standstill, causing travel chaos for hundreds of thousands of passengers just days before Christmas.
“Each time we believe we get close to the operator, the drone disappears; when we look to reopen the airfield, the drone reappears,” Sussex Police Superintendent Justin Burtenshaw told the UK’s Press Association.

A drone had been spotted near the runway as recently as midday, the airport’s Chief Operating Officer Chris Woodroofe told journalists. He could not say when the major international airport, located south of London, would reopen.
Aviation expert Jon Parker told CNN he’d “seen nothing on this scale before,” in terms of deliberate disruption by a drone to a major UK airport.
“The usual practice (when a drone is spotted) is to suspend flights for half-an-hour, which is the usual battery lifespan for drones,” explained Parker, a former Royal Airforce fighter pilot and head of drone training company Flyby Technology.

But in the case of Gatwick, “whoever is responsible for this has had several batteries and have brought their drones back to the ground to put new batteries on them,” he said.
It is illegal to fly drones within 1 kilometer (0.6 miles) of a UK airfield boundary, with perpetrators facing up to five years in prison.
There is no indication the incident at Gatwick is terror-related, local Sussex Police said. It added that 20 police units from two forces were searching for the drone operators.
A spokesperson for Prime Minister Theresa May called the act “irresponsible and completely unacceptable.”
The drones used to disrupt flights at Gatwick are believed to be of an “industrial specification,” according to Sussex Police.
This means that a device is not an off-the-shelf consumer drone, but something bigger or more complex, or perhaps expertly home-made, explained Lewis Whyld, CNN’s drone operator and photojournalist.
He added that drones can have huge ranges, with some of the more powerful ones controlled from up to 10 miles (16 kilometers) away.
Drones don’t necessarily need an operator, added Whyld. They could be pre-programmed to follow a route using GPS, he said.
Passengers left in the lurch
Gatwick was thrown into turmoil on Wednesday and Thursday, with passengers stranded at the terminal or re-routed to other airports.
Around 110,000 passengers on 760 flights were scheduled to depart and land at Gatwick on Thursday morning, a spokesperson told CNN.
Passengers due to land at Gatwick were instead arriving in Manchester, Luton or Heathrow in the UK, or even as far afield as Paris and Amsterdam.
One passenger, Matt, said on Twitter he was waiting to board a coach at Manchester in the north of England — two hours after he was supposed to arrive at Gatwick at the other end of the country.
At Berlin’s Tegel Airport, heavily pregnant British woman Imogen Fletcher was left stranded for hours after her EasyJet flight to Gatwick was canceled.
The IT developer told CNN she had been on her way home for Christmas with her husband and daughter, but on Thursday morning she was left scrambling to find another flight.
Passenger John Belo told CNN he was stuck on a plane at Gatwick for four hours. Belo had been due to fly to Porto in Portugal at 8.45 p.m. on Wednesday night, in what should have been a two-and-a-half hour journey. But after hours of delays he finally arrived in the city at 2 a.m. the following morning.
