GATWICK: London’s Gatwick Airport reopened on Friday after a mystery saboteur wrought 36 hours of travel chaos for more than 100,000 Christmas travellers by using drones to play cat-and-mouse with police snipers and the army.

After the biggest disruption at Gatwick, Britain’s second busiest airport, since a volcanic ash cloud in 2010, Gatwick said around 700 planes were due to take off on Friday, although there would still be delays and cancellations.

Britain deployed unidentified military technology to guard the airport against what Transport Secretary Chris Grayling said were thought to be several drones.

“I think passengers are safe,” Grayling said. “This kind of incident is unprecedented anywhere in the world.” The motivation of the drone operator, or operators, was unclear. Police said there was nothing to suggest the crippling of one of Europe’s busiest airports was a terrorist attack.

Gatwick’s drone nightmare is thought to be the most disruptive yet at a major airport and indicates a new vulnerability that will be scrutinised by security forces and airport operators across the world.

The army and police snipers were called in to hunt down the drones, thought to be industrial style craft, which flew near the airport every time it tried to reopen on Thursday. The last time a drone was spotted at airport was at 2200 GMT on Friday.

The perpetrator has not yet been detained but the police said they had a number of possible suspects. No group has claimed responsibility publicly and police said there was no evidence another state was involved.

Sussex Police Assistant Chief Constable Steve Barry said they were keeping an open mind about who was responsible.

“In terms of the motivation, there’s a whole spectrum of possibilities, from the really high-end criminal behaviour that we’ve seen, all the way down to potentially, just individuals trying to be malicious, trying to disrupt the airport,” he said.

After a boom in drone sales, unmanned aerial vehicles have become a growing menace at airports across the world.

In Britain, the number of near misses between private drones and aircraft more than tripled between 2015 and 2017, with 92 incidents recorded last year.

The British Airline Pilots’ Association (BALPA) said it understood “detection and tracking equipment” had been installed around Gatwick’s perimeter.
