Europe Aviation Faces Wave of Bomb Threats, Disrupting Flights

Europe's aviation sector is grappling with an unusual surge of bomb threats targeting passenger planes, with at least 25 flights receiving false alarms on Thursday alone. These threats have forced aircraft to make emergency landings and undergo security checks across the continent. For instance, a flight from Dublin to Rome diverted to a French air force base after a bomb threat, according to the French Prime Minister's office. Similarly, a Wizz Air flight from Milan landed safely in Bucharest, Romania, following a threat. Bulgaria reported threats against three flights, with two landing in Sofia and one in Plovdiv. A LOT Polish Airlines flight from Warsaw landed in Brussels, and a Finnair flight from Helsinki to Rome was escorted by Italian fighter jets but landed at its destination. Czech police also reported four flights bound for Prague received bomb threats shortly before landing.

These incidents follow a series of similar events in recent days, including at least seven flights in Poland, Italy, Spain, and Bulgaria on Tuesday that received bomb threats. While security checks on those flights found no explosives, the disruptions caused significant flight delays and scrambled fighter jets. Aviation experts suggest that after major security events, such as the Flydubai incident, anonymous threats, even if false, may increase, drawing parallels to the surge in bomb threats after the 9/11 attacks.

Security experts note that sending such threats is low-cost but can incur tens of thousands of euros in expenses for airlines due to emergency landings, ground services, passenger accommodation, and subsequent flight delays. The current wave of threats poses a complex challenge for global aviation. Authorities must take every threat seriously while also guarding against exploitation by malicious actors aiming to cause repeated disruptions. There's also concern that these false alarms could be a tactic to "fatigue" security systems before a real attack. European security officials are investigating whether these are pranks, copycat incidents, or a coordinated effort to disrupt air travel, with some British officials labeling them "malicious deception acts." The lack of a clear pattern in targeted airlines and destinations suggests a general disruption of European aviation as a primary goal, according to one aviation security expert cited by Reuters.

Security protocols involve assessing the threat's origin, timing, and nature. Factors like whether the threat came from a phone call, a passenger, or crew, and whether it occurred before takeoff, in mid-air, or after landing, are crucial. Security agencies also consider internal threats, such as ground staff or technicians planting suspicious items. The U.S. Federal Aviation Administration (FAA) guidelines differentiate between general and specific threats, requiring air traffic controllers to inform pilots and offer expert consultation for targeted threats. On the ground, planes facing specific threats are moved to isolated areas for inspection.

In Israel, security officials believe the stringent security checks at Ben Gurion Airport significantly reduce the risk of explosives being placed on departing aircraft. However, they emphasize that even robust security doesn't eliminate the need to treat post-takeoff information seriously. This past month, an Austrian Airlines flight from Tel Aviv to Austria made an emergency landing in Sofia due to an anonymous bomb threat received in Austria. Five days prior, two Delta flights from New York to Israel also received bomb threats, with no suspicious items found on either aircraft.
