Forget Gatwick, Why The Deadliest Terrorist Threat From Drones Is Not At Our Airports

At a half-day closed session with one of the UK’s leading Premier League soccer clubs earlier this year, the stadium’s security director told the room “there are two things that terrify us: a large vehicle driven at speed at thousands of fans as they head home after a match, and, of course, drones.”

The floor to ceiling windows of the meeting room, high in the stands, looked down on a vast, empty stadium with the immaculate playing field far below. The meeting had covered every aspect of security, from cyber and the dark web to player safety and hooliganism. Inevitably, terrorism was high on the agenda. Looking out at that open space where 50,000 plus people gather 25 plus times a year, the threat from drones did not require elaboration.

Sporting events are open air, mass gatherings. As are music concerts and festivals. The English Premier League averages around 40,000 fans per game. American Football in the US is higher, with an average of 75,000 people at each of the 256 games. The numbers attending a large music festival, such as Glastonbury or Coachella or Donauinselfest, can be many times more.

Although international terrorism always targets headlines, Al Qaeda’s tentacled network and ‘spectacularization’ have been traded for Islamic State’s ruthless theater of evil and affiliated radicalization. Planning has given way to opportunism. Drones represent a halfway house. Some expertise is required, especially if adapting commercial drones, and the payload needs to be developed and delivered. But, get all that right and target locations are seemingly wide open.

We’ve Been Warned

In October 2018, FBI Director Christopher Wray told the US Senate Homeland Security Committee that the terrorist threat from a drone attack is now escalating. “[Drones] will be used to facilitate an attack in the US against a vulnerable target, such as a mass gathering.” A year earlier, he had told senators “we do know that terrorist organizations have an interest in using drones. We’ve seen that overseas already… the expectation is that it’s coming here. They are relatively easy to acquire, relatively easy to operate, and quite difficult to disrupt and to monitor.”

The same month, an Islamic State propaganda poster depicted a drone carrying a menacing payload towards the Eiffel Tower in Paris and a stark capitalized warning: ‘Await For Our Surprises’. Now, in the wake of Gatwick, Islamic State has mocked-up posters of a drone attack on New York City.

According to U.S. Secretary of Homeland Security, Kirstjen Nielsen, in an opinion piece in the Washington Post: the threat from drones “is outpacing our ability to respond…terrorist groups such as the Islamic State aspire to use armed drones against our homeland and US interests overseas…We have already worked with our partners to stop terrorist plots that could have involved drone technology.”

In December 2018, with the chaos at the UK’s second busiest airport, our vulnerability to drones in high-profile, highly-secure public spaces has been hammered home in quite spectacular fashion.

Christmas Chaos At Gatwick

Between 19th and 21st December, more than 60 reported drone sightings in or around the single runway at Gatwick forced the full closure of the airport, canceling more than 1,000 flights and hitting the travel plans of nearly 150,000 passengers. The extended chaos was a publicity nightmare for law enforcement and the airport; it clearly demonstrated that despite proximity flying bans and geofencing technology, an open space was vulnerable to an industrial specification drone.



Legal deployments of commercially available counter-drone technology are limited in the US and UK, the use of GPS and radio jamming technologies in and around built-up urban areas and communication hubs such as airports is fraught with risk. But it now seems inevitable that something needs to change. According to Oleg Vornik, CEO of Droneshield, a specialist provider of detection and disruption technologies, “drones represent a major threat to aircraft and can easily create disruption as witnessed at Gatwick. We expect copy-cats to continue driving such incidents going forward.”

Earlier this year, the UK Ministry of Defence acquired Drone Dome counter unmanned aircraft systems (C-UAS), from Israel’s state-backed manufacturer Rafael. According to press reports, it was this system that was eventually deployed at Gatwick. Drone Dome includes radar and electro-optical detection modules, a ‘soft kill’ (communication jammer) that was included in the MOD procurement and a ‘hard kill’ (laser) that was not.

Honed On The Battlefield

More than three-thousand miles from Gatwick, Islamic State drones have flown countless raids high and fast above the barren Iraqi frontline and its shelled-out buildings, armed with rudimentary grenades. Videos can be found online of soldiers firing automatic weapons at drones small enough and high enough to make tracking them with the naked eye difficult. The drones are standard commercial models, sourced from the Far East through a convoluted supply chain. In September, police in Denmark reported that two people had been arrested for attempting to acquire drones to be shipped to Iraq or Syria.

In July this year, Houthi rebels claimed on their propagandist television station that they had attacked Abu Dhabi airport with a drone, to avenge the bloody conflict in Yemen. The attack was denied by UAE authorities. A month later, two industrial drones were reportedly used in a failed assassination attempt on Venezuela’s president Nicolás Maduro. The same summer, Russian authorities claim they thwarted planned terrorist drone attacks during the soccer World Cup.

Now, with the reported re-emergence of Al Qaeda, the potential for a sophisticated, high-profile attack using drone skills honed on the battlefields of Syria and Iraq and Yemen is very real. According to Droneshield’s Oleg Vornik, “there is a major danger from drone-related terrorist activities, with Al Qaeda and other organizations reported to be regrouping and re-evaluating their strategies and their use of drones well-known.”

In October, UK security minister, Ben Wallace, warned that “terrorists continue to explore new ways to kill us on our streets: chemical and biological weapons are marching in closer. They have developed and worked on a better arsenal. We have to be prepared for the day that might come to our streets here.”

An adapted commercial drone that can carry a grenade can carry a chemical or biological weapon. The UK policing counter-terror lead, Neil Basu, has said that “these things have been used on the battlefield and what’s used on the battlefield will eventually be adapted to be used on domestic soil.”

What Next?

Markets and Markets forecast that the value of the worldwide drone market will increase from $18 billion in 2017 to more than $50 billion by 2025. That’s a seriously large number of flying objects. Understandably, in the wake of Gatwick, much has been made of the threat to aircraft and passengers from a targeted attack during take-off or landing. In reality, deliberately taking out a plane with a drone is harder than it’s been painted. Such an incident is more likely to be the result of an accident than an attack. And that’s a solvable problem with technology and legislation. The calls for tougher drone regulations and infringement penalties are aimed at resolving this risk. Terrorists are not deterred by such penalties.



We will see counter-drone technology deployed around airports and very high-profile locations. Droneshield reports that they have “fielded products across a number of key markets and customers this year and expect deployments to rapidly rise in 2019.” But it’s not possible to protect everywhere. Terrorist attacks on western soil using drones would be more straightforward and effective on mass gatherings in open public spaces. We will be too vulnerable if we take a physical defensive approach. The only solution is significantly tighter restrictions on the equipment itself. What can be imported and purchased. How devices can be used. Regulations around device controls and ease of adaptation.

Gatwick may have been a holiday-season PR fiasco, ruining seasonal travel plans for many. It should also be a wake-up call for all.
