Airline flight crews are increasingly having to operate in an environment where missiles, military drones and other airborne hazards intrude into commercial corridors and airports. Recent attacks tied to the escalation of hostilities in the Middle East have put hundreds of missiles and attack drones into skies that are also used for civilian travel, forcing flight crews and airport operators to adapt on the fly.
The current uptick in danger follows a pattern in which conflicts from Ukraine to Afghanistan and Israel have cumulatively tightened the margin of safe airspace available to civilian aircraft. Pilots and aviation security specialists say those shifts have raised the stakes for routine operations and intensified pressure on crews over route planning, monitoring and emergency preparedness.
"We are not military pilots. We are not trained to deal with these kinds of threats in the air," said Tanja Harter, a pilot with Middle East experience and president of the European Cockpit Association. She warned the accumulation of security challenges across multiple theatres can create "fear and anxiety" for pilots, even as airlines and industry groups try to provide peer support programs to address crew wellbeing.
Recent Iranian retaliation that targeted U.S. and allied positions has included strikes on airports, prompting cancellations and the grounding of dozens of flights from hubs such as Dubai and Abu Dhabi. A limited number of rescue flights have made it through to evacuate thousands of stranded passengers, but disruptions remain significant for commercial operations in the region.
Industry participants said that navigation anomalies and deliberate interference such as GPS spoofing - which can falsely indicate an aircraft's position - have compounded the risk picture, alongside a higher number of missiles and unmanned aerial vehicles being launched into or near civil air routes.
Planes en route to repatriate citizens have been turned back when regional missile fire threatened flight safety. An Air France flight tasked with bringing French nationals home from the United Arab Emirates aborted its journey after missile fire was detected. Separately, a Lufthansa pilot opted to divert from a planned landing in Riyadh and instead proceeded to Cairo because of concerns about regional security conditions.
In Lebanon, aviation officials and local captains said crews trained in the region have learned to expect and manage crises. Video footage from March 5 captured aircraft taking off as smoke rose over parts of Beirut, illustrating how quickly routine airport operations can intersect with active hostilities.
"Middle East pilots have always faced crises, so from the start we trained how to deal with contingencies, emergencies and everything else," said Captain Mohammed Aziz, director general of Lebanon’s civil aviation authority. "No one can give you a guarantee that they won’t bomb the airport or will bomb the airport."
One pilot at Middle East Airlines with a decade of flying experience said routes into Beirut have grown more complicated. Historically, shoulder-fired anti-aircraft missiles in Lebanon typically reached altitudes of about 15,000 feet, and crews would ascent to avoid that envelope while carrying additional fuel to allow for diversions if needed. He added that while many missile strikes occur far enough away from flight paths to present limited direct risk, the operational workload in the cockpit often leaves little time to process what is happening outside.
"You’re actually busy enough on the plane trying to make sure you have clearance to land, that everything is in order, so you don’t have time to process your emotions over what’s happening outside the plane," the pilot said.
The threat is not confined to the Middle East. Since the 2022 invasion of Ukraine, drones have become a prominent weapon in that theatre, and episodes of drone activity have disrupted airports across Europe, from Stockholm to Munich. In several cases, officials suspect links to the conflict, though confirmations are sometimes lacking.
Drones present a particular detection and mitigation challenge. They are often small, emit no transponder signal and can be difficult for the primary radar systems that support airport operations to identify. Specialized radar and counterdrone systems exist but are commonly operated by law enforcement or military units rather than by airport operators directly.
"Drones are not easily detected," said Christian von D’Ahe, a commercial pilot of 15 years and head of the Danish Air Line Pilots Association. "We can see them in the air, and they’re very small. So sooner or later, something will happen."
Pilots and safety observers say a drone strike on critical airframe components - for example an engine or a wing - could lead to catastrophic consequences such as engine failure or loss of manoeuvrability. That risk profile underlies why airports and authorities have invested in a variety of mitigation tools, including radar upgrades, frequency sensors, jamming equipment and systems designed to deceive or redirect drones away from flight paths.
Despite technology options, response choices are constrained. Safety and legal concerns prevent airports from using force to neutralize drones in many cases, limiting operators to tracking, reporting and, where necessary, suspending operations. Tim Friebe, an air traffic controller in Germany and vice president at the Air Traffic Controllers European Unions Coordination (ATCEUC), described the problem as a growing threat with few practical options beyond airport closures when a device is spotted.
"For now we have reports, pilot reports, or sometimes controllers spot drones. The problem is there’s not much you can do except shutting down the airport," Friebe said.
Last year, uncrewed aircraft caused sizable interruptions at major airports, including Munich and London Gatwick, prompting operators to enhance their foreign-object detection and counterdrone capabilities. Industry officials said such investments have increased, but noted that operational resilience remains uneven across facilities.
A commercial pilot based in Germany, Moritz Burger, described a close call during an approach to a European airport when he sighted an object that appeared for only a second or two. He compared it to a balloon with a structural element beneath it and said the encounter offered no realistic window for evasive action.
"When you encounter such a near-miss or some passing object, there is not enough time to react. So it is unrealistic to expect that pilots could fly around such an object. There’s pretty much nothing we can do," Burger said.
Commercial firms that produce counterdrone technology say the volume of violations is significant. Dedrone reported there were more than 1.2 million drone violations in the United States in 2025 and suggested the number could grow in coming years. While the figures underscore the scale of the challenge, aviation authorities and service providers say detection and legal response mechanisms lag behind the evolving threat.
Industry officials and pilots stressed that while many incidents do not result in direct contact with aircraft or immediate physical harm, the cumulative effect of constrained airspace, technological interference and the prospect of missile or drone engagement is placing additional strain on crews and air traffic systems. That strain touches not only operational safety planning but also crew mental health as people charged with passenger safety navigate unprecedented levels of airborne danger.
In this climate, airports, airlines and regulators are grappling with how best to prioritize investments and operational changes to protect civilian aviation. Options include bolstering detection systems, closer coordination with military and law enforcement assets, and enhanced training and peer support for flight crews. Yet the limitations on active countermeasures and the inherently mobile nature of contemporary threats mean that uncertainty will likely remain a feature of daily operations for the sector.
The interactions between geopolitical conflict, fast-moving unmanned systems and the routines of commercial aviation have made airspace management a more complex discipline. For pilots and controllers, the message is clear: missions that once focused on weather and traffic must now account for hazards that were previously the exclusive concern of military aviators.
