Could five laser strikes over Dilbeek expose a weak point in Brussels Airport’s approach?

Five pilots approaching Brussels Airport reported laser beams directed at their cockpits above Dilbeek on Sunday evening, 16 August, according to VRT NWS, De Morgen and HLN. The aircraft were close to landing when the pilots were hindered, making the five reports in one evening a concentrated aviation-safety incident rather than an isolated nuisance. Police are investigating, but no suspect, injury or confirmed disruption to airport operations had been announced by Monday.

The available reporting does not establish whether one person was responsible for all five incidents, precisely where the beams originated or what type of laser device was used. It also does not identify the airlines, flights or number of passengers involved. Those gaps matter: directing a laser towards an aircraft can range from a brief distraction to glare, temporary loss of vision or disorientation at a moment when pilots have little altitude and a heavy workload.

Belgium’s Federal Public Service Mobility says projecting any laser beam into Belgian airspace requires prior authorisation from the Directorate-General for Air Transport because it may obstruct or endanger aviation. Dilbeek’s own general police regulation separately prohibits projecting laser or similar light into the airspace above the municipality without the mayor’s permission. Those rules cover authorised displays as well as public-order concerns; deliberately tracking an aircraft raises a more serious question of endangering flight safety under federal aviation law.

The immediate concern is operational resilience. A laser does not need to damage an aircraft to impose costs. If a crew’s vision is affected, air-traffic controllers may have to warn following aircraft, alter an approach or arrange medical checks. Airlines can then face delays, missed connections and crew or aircraft displacement. None of those consequences has been confirmed in this case, so they should be understood as the sector’s exposure rather than as a reported bill from Sunday night.

That exposure sits inside a large commercial system. Brussels Airport Company, the operator of Brussels Airport, recorded 24.4 million passengers and 198,000 commercial flight movements in 2025. Passenger numbers were 3.3% higher than in 2024 and movements rose 2.8%, according to company traffic data. Its 2025 revenue increased 6% to €828 million, while operating costs climbed from €439 million to €472 million, partly because of higher traffic, security and maintenance expenditure. The company says the airport supports 64,000 direct and indirect jobs, although that economic-impact estimate is its own.

For passengers and businesses, the practical significance is therefore straightforward. A single reported strike may be absorbed without visible disruption, but repeated illumination on the same approach creates a safety risk with the potential to disturb passenger schedules and time-sensitive cargo. Brussels Airport is an important base for passenger airlines and an international freight gateway serving pharmaceutical, express and other high-value supply chains. Reliability is part of what customers buy from that network.

Laser interference is not new in Belgium. Parliamentary records show that 89 incidents were reported nationally in 2010, compared with five in 2009; 34 of the 2010 reports concerned Brussels Airport. The government response at the time included pilot notices and coordination among air-traffic control, local police and federal police aviation services. The historical figures are too old to describe today’s frequency, but they show that detection and identification have long been difficult: authorities said at the time that no perpetrator had been identified in those 89 cases.

Today, aviation occurrences are reported through the European reporting system under EU Regulation 376/2014, with Belgian reports feeding into the European Central Repository. The Directorate-General for Air Transport uses that information for safety analysis, while criminal or public-order inquiries remain a police and judicial matter. That division helps explain why the pilots’ reports, the police search and any later safety assessment may proceed on separate tracks.

The Dilbeek location adds a sensitive local context, but not an established motive. Residents have repeatedly voiced concern about aircraft noise and flight paths, and Brussels Airport says runway use and routes depend on federal instructions, timing and weather rather than on the airport operator alone. Nothing currently connects Sunday’s laser incidents to the noise dispute. Treating that possible link as fact would unfairly implicate residents using lawful complaint channels.

The relevant constituencies are not truly divided over whether pointing lasers at cockpits is acceptable. Aviation authorities, pilots and airlines regard it as an avoidable safety threat. Dilbeek residents seeking relief from aircraft noise, meanwhile, have legitimate administrative and political routes for challenging flight-path policy; those concerns neither explain nor excuse the reported conduct. The useful distinction is between debate over how the costs of aviation are distributed and interference that puts crews and passengers at risk.

The next concrete development should come from the police investigation: witness accounts, camera footage or a more precise origin point may establish whether the five reports came from one location. Authorities may also clarify whether any crew required medical attention or whether air-traffic procedures were changed. Until then, the verified core remains narrow but serious—five pilots reported laser interference during their approach, while the person or people responsible and the operational consequences remain unknown.
