Two residents of the town next to London Gatwick are under arrest in connection with the days-long disruption to London’s second airport, with police citing them in the usual style as “a 47-year-old man and a 54-year-old woman, both from Crawley.”
The charges are “suspicion of disrupting services of civil aviation aerodrome to endanger or likely to endanger safety of operations or persons.”
Superintendent James Collis from Sussex Police explained, “as part of our ongoing investigations into the criminal use of drones which has severely disrupted flights in and out of Gatwick Airport, Sussex Police made two arrests just after 10pm on Friday December 21.
“Our investigations are still on-going, and our activities at the airport continue to build resilience to detect and mitigate further incursions from drones, by deploying a range of tactics.”
#GatwickDrones | Around 10pm today we made 2 arrests in connection with criminal drone activity at Gatwick Airport. Proactive investigations are still on-going: we urge the public to contact us if they believe they have information that can aid us further. https://t.co/dOmKw4GnfO

No further details are available, although Gatwick has a long history of antagonism from residents opposed to expansion of the airport, usage of the airfield’s secondary relief runway as a second runway, additional flights, and other local concerns. Further, UK airports have frequently been targeted by protestors seeking to highlight the role of aviation in contributing climate change. There would be little surprise either at Gatwick Airport or in the UK aviation industry if indeed it turned out that the disruption had been down to one or a combination of these factors.
Impressively, very few flights were showing cancelled through the day of December 22, the Saturday before Christmas. Delays of one to two hours were, however, fairly commonplace, but a surprising number of flights were also on time. Gatwick expected to operate the vast majority of the 757 flights scheduled Saturday, carrying some 124,500 passengers.
As of Saturday evening, cancellations on the airport’s flight information display system showed cancellations from Air Arabia, Kabo Air and WOW Air, each with one single cancellation. Sunday’s schedule was showing as largely expected to run to time.
“Our runway is open and we aim to run a full schedule on Saturday 22 December,” said Gatwick Airport in a statement.
Our runway is open. Passengers are advised to check with their airline before travelling to the airport.

“Passengers should expect some delays and cancellations as we continue to recover our operations following three days of disruption and are advised to check with their airline before travelling to the airport. Safety is Gatwick’s top priority and we are grateful for passengers’ continued patience as we work to get them to their final destination in time for Christmas.”
The fallout, however, will be substantial. Airports, passengers and authorities around the world have been watching the empty skies south of London this week — as will nefarious actors interested in disrupting airport operations, whether owing to local airport expansion reasons, aviation’s impact on the environment and contributions to climate change, or simply those using this sort of activity to make a point about their cause or politics.
Speed, Inform, Delay, Avoidance and Report
British pilot union BALPA reissued its advice to aviators in the event of drone sightings, which is made up of five parts: Speed, Inform, Delay, Avoidance and Report.
On speed, says BALPA to pilots, “if a drone has been reported, consider requesting a speed reduction: initially to minimum clean, including during departure; on STAR, initial or intermediate approach, request a further reduction to 180kt; on final approach observe ATC speed constraints to maintain separation.” At the same time, air traffic controllers should expect pilots to request speed reductions.
Under “inform”, pilots should inform ATC immediately upon sighting a drone, says BALPA, passing “as much accurate information as possible about the drone sighting: location, altitude, lateral and vertical separation, [whether it] was moving or stationary, [its] size, shape and appearance (e.g. quadcopter, camera underneath, colour, etc).”
Once notified, air traffic controllers should inform their supervisors, neighbouring ATC sectors, pilots on the frequency and those joining the frequency.
Both pilots and ATC should plan for delays, diversions and closure of the airspace or aerodrome, BALPA says. Pilots should “request alternative routings or radar vectors if deemed necessary,” while air traffic controllers should “consider the safety of the operation and avoid the area if deemed necessary”.
Both pilots and air traffic controllers should file appropriate safety reports as established by their airline and air navigation service provider, respectively.
Delayed governmental action
Authorities from the airport to local police to the UK armed forces to the UK government have been sharply criticised over the length of time that a very limited number of people were able to take out critical national infrastructure.
Reports in UK media suggested that a shortage of civil servants to manage and direct legislation concerning drone safety, driven by a lack of staff owing to preparations for the UK to leave the European Union, had delayed governmental action on the topic.
“We are working with industry on the development of counter-drone technology to protect against the malicious use of drones and we offer advice to businesses on specific protective security measures,” a government spokesperson said.
“We have consulted on how this technology and other counter-measures should be best used and will be responding soon. We continue to support the police in their response to this illegal activity.”
