European aviation authorities are grappling with an unprecedented surge of bomb threats targeting commercial flights, leading to a series of emergency landings and security alerts across the continent. On Thursday, November 5, multiple aircraft were forced to divert or make emergency stops as the latest in a string of incidents tested the resilience of international air travel safety protocols.
The wave of threats, which has occurred twice within a single week, follows a similar pattern of disruptive alerts that previously proved to be hoaxes. While no explosive devices have been discovered during inspections, the frequency of these incidents has triggered an emergency information-sharing mechanism across the European Union. Officials cannot yet draw conclusions about whether the incidents are related.
Italian Bomb Disposal Experts Clear Aegean Flight After Security Threat
The disruption affected several aircraft, with forced landings across European countries. In some cases, fighter jets were scrambled. Two Aegean flights were affected. Checks by Italian bomb disposal experts on an Aegean aircraft operating the Thessaloniki–Milan route were completed at midday Thursday with a negative result.
Aegean issued a statement confirming that, in close cooperation with the relevant authorities, all established security protocols were implemented. Following the completion of these procedures and the confirmation that the threats were baseless, the affected flights were cleared for departure. The airline emphasized that the safety of passengers and crew remains its highest priority.
Analysis of the Security Disruption
The incidents have been described as unprecedented in number. They have intensified concerns regarding hybrid threats against critical European infrastructure, particularly in the heightened security environment following the 2022 Russian invasion of Ukraine.
Eliran Almog, CEO of the cybersecurity firm Cyviation, suggested that these repeated threats may serve to disrupt the flow of air traffic and test the reaction times of airlines, airports, and national authorities. Former airline captain Martin Drake, a technical advisor for the pilots’ union BALPA, explained that airlines utilize a “traffic light” scale to assess threats.

Captain Helen Asqu, a former head of flight safety, stated that 99% of such threats never reach the cockpit.
Coordinated Response from European Authorities
Apostolos Tzitzikostas stated that it is not yet possible to draw conclusions about whether the incidents are related. He condemned any threat against civilians as “unacceptable,” said that ensuring the safety and protection of citizens remains a priority, and confirmed that the EU information-sharing mechanism for civil aviation security has been activated. He is monitoring the situation closely and is in contact with affected member states and the European Union Aviation Safety Agency. He has asked national authorities, which are responsible for evaluating security threats, to investigate the incidents, apply appropriate security measures, and cooperate closely with airport operators, airlines, and law enforcement authorities.
In the United Kingdom, the Minister of Transport said that the country has some of the strongest security systems in the world and follows specific procedures for handling false and malicious threats, and that the recent incidents were exactly such cases. She added that the authorities take these threats seriously.
European authorities continue to monitor the situation closely, with national agencies responsible for evaluating the credibility of individual threats and applying appropriate security measures.
