Britain's two biggest airports, Heathrow and Gatwick, are investing in anti-drone technology following severe disruption at Gatwick caused by drone sightings in the run-up to Christmas, spokesmen said on Friday. The British army was deployed to London Gatwick on December 20 after the airport grounded all flights, leaving tens of thousands of passengers stranded over some of the busiest days of the year.

"We have invested several million pounds (dollars, euros) in providing ourselves with the equipment and the technology that the armed forces deployed over Christmas," a Gatwick Airport spokesman told AFP. He said investment was made "in the days immediately after" the disruption but declined to give details, saying only that it had "equivalent capabilities" to the technology used by the military. A spokesman for London Heathrow, Britain's biggest airport, also said they would be investing in anti-drone technology.
