Heathrow and Gatwick airports are set to invest millions of pounds in anti-drone technology following the huge disruption experienced at the Sussex hub before Christmas.
According to the BBC, the equipment can detect and jam communications between drones and their operators.
The technology was used by the RAF last month to halt drone sightings that forced Gatwick to close its runway several times – including a full day – in the busy run-up to Christmas.
A couple was arrested in connection with the drone attack but was later released without charge. Sussex Police is still investigating the case.
Gatwick airport said it had ‘learned lessons’ during the chaos that ensued and has spent £5 million to prevent future attacks, reports say. Heathrow has now also confirmed it will buy anti-drone technology, though neither airport has confirmed the equipment they plan to use.
A Heathrow spokesman said: “The safety of our passengers and colleagues remains our top priority. Working closely with relevant authorities including the Met Police, we are constantly looking at the best technologies that help remove the threat of drones.”
