Drones ground flights across Belgian airports

Belgium scrambled to respond this week after multiple drones forced the closure of airports and even a military air base—a rare, multi-site incursion that officials are now calling a “coordinated attack.”

According to a November 5 Reuters report, Belgian Defence Minister Theo Francken told parliament that large drones were flying in formation, deliberately attempting to foment disruption. The situation has escalated to a national security issue, prompting an emergency meeting of government ministers and aviation security chiefs.

This marks one of Europe’s most serious Unmanned Aircraft System (UAS) incursions to date—testing the continent’s airspace defense and regulatory frameworks.

The difference between “drones” and “UAS”

While media headlines refer to “drones”, aviation law does not. The technical and legal term used by the European Union Aviation Safety Agency (EASA) is Unmanned Aircraft System (UAS).

“Drone” is a colloquial label. Within regulatory frameworks, an Unmanned Aircraft System includes the aircraft itself, its control station, communication links, and all operational components.

This distinction matters. “Drone” sightings aren’t treated as casual hobbyist activity—they fall under complex UAS risk management and airspace safety protocols that require verification by trained personnel, not the general public.

Who confirms a drone sighting? The “qualified observer”

In public discussion, skeptics (such as debunker Mick West) have suggested that airports may be misidentifying airplanes as drones. But that assumption disregards the EASA-defined chain of verification.

According to the “Drone Incident Management” at Aerodromes manual:

“Qualified observer”: someone who, due to their job profile or training, is a trusted source when it comes to sighting of drones or UAS near an aerodrome.

These individuals—airport operations staff, air traffic controllers, or law enforcement observers—form part of the Drone Incident Management Cell (DIMC), a multi-agency coordination hub that cross-verifies all sightings before any shutdown occurs.

Inside the drone incident management process

EASA’s Drone Incident Management at Aerodromes manual (Parts 1–3) provides the architecture for how airports across Europe handle UAS incursions.

Only Part 1 is public; Parts 2 and 3 are marked as:

“Sensitive material made available on a need-to-know basis for Official Use Only.”

Even so, the released framework gives insight into how incidents like Belgium’s are managed.

The 10 phases of preparedness

Aerodromes are required to implement ten phases of incident management—from risk assessment and information gathering to decision-making and post-incident review.

This system is designed to mitigate unauthorized UAS use through coordination between:

National and local authorities
Air traffic control
Airport safety/security
Law enforcement

Each phase includes formal verification and restoration procedures, ensuring that airspace closures are neither arbitrary nor reactionary.

How risk is assessed

Before an airspace closure occurs, airport and defense authorities perform a risk assessment considering:

Probability of a real UAS presence
Severity of potential impact
Effectiveness of existing mitigations

If the threat is categorized as unacceptable, only then is the airspace temporarily restricted—a process often lasting minutes, not hours.

Residual delays follow due to ripple effects in scheduling, not from ongoing confusion.

From detection to decision: the flow chart

The Drone Incident Management Flow Chart (Annex 3.2) details how a sighting transitions into a verified incident:

Detection systems or qualified observers report a sighting.
The Drone Incident Management Cell (DIMC) cross-checks information.
If the drone is unauthorized, threat level is determined—High, Medium, or Low.
Air traffic and security responses are deployed according to established threat protocols.
Operations are restored once the threat is neutralized.

This flow ensures that every action, from delay to closure, is evidence-based and coordinated across multiple agencies.

Why Belgium’s case matters

Belgium’s recent drone incidents are not isolated; they may represent a new phase of coordinated UAS incursions targeting civilian and military infrastructure.

The involvement of formation-flying large drones suggests organization, resources, and intent beyond nuisance or hobbyism. As Minister Francken warned, this was “a coordinated attack designed to foment disruption.” That phrase shifts the narrative from aviation safety to national defense.

The bigger picture

From the Gatwick Airport incident in 2018 to UAS activity over Danish power plants in 2024, Europe has faced a growing challenge: identifying, verifying, and neutralizing aerial threats that fall below traditional radar coverage but above public comprehension.

The Belgian case demonstrates that EASA’s multi-layered incident management system works as intended—structured, deliberate, and security-oriented.

These shutdowns are not panic.

They are protocol in action.

Update: Nov 5–6, 2025 — Urgent security talks and next steps

On Nov 5th, 2025, Belgian media reported that the Prime Minister convened urgent security talks following a request from the Interior Minister, with the meeting scheduled for Thursday morning (November 6th).

In remarks captured after the meeting (video: DWS News / AC1E), multiple officials emphasized that the government’s response is focusing on a three-part model: detection → identification → possible neutralization, while also acknowledging that neutralizing drones—especially over civilian areas—is legally and practically complex.

One minister highlighted “good coordination” among security services and said Belgium’s telecommunications portfolio would contribute to improving detection and counter-drone capabilities, including potential changes to the regulatory and legislative framework and additional resources for defense and police.

Another senior official stressed that while drones have legitimate public benefits (e.g., emergency services), flying a drone over an airport is already illegal and can carry severe penalties when aviation safety is endangered. The overall message: Belgium is treating the incidents as a serious, evolving security threat, and is moving to strengthen both operational capability and legal authority to respond.

Final thought

The next time headlines say, “airport closed after drone sighting”, remember:

Behind that phrase lies a complex system of trained observers, risk assessment frameworks, and cross-agency decision cells operating in real time to keep European airspace safe.
