A LOT Polish Airlines Airbus A320, wet-leased to Electra Airways, triggered a three-nation fighter jet scramble on 30 June 2026 after its transponder erroneously broadcast squawk 7500 over Bulgarian airspace. Bulgarian MiG-29s, Turkish F-16s, and Israeli F-16s intercepted the aircraft as it entered Turkish airspace, prompting denial of landing clearance in Israel and diversion to Burgas Airport due to crew duty time limits. While Bulgaria’s Transport Ministry attributes the event to a technical transponder failure, LOT and Turkish authorities cite pilot error for entering the wrong code. The aircraft was searched, confirmed safe, and resumed service, underscoring how transponder glitches can activate NATO air-policing protocols across multiple jurisdictions without actual security threats.
