How a radio glitch triggered a false hijack alert in Germany

German authorities briefly closed Nuremberg's Albrecht Dürer airport and scrambled fighter jets after a passenger plane mistakenly triggered a hijack alert due to a radio malfunction. Corendon Airlines flight XR456, a Boeing 737-800 flying from Corfu to Nuremberg, sent out an emergency code 7500 over Croatia, indicating a hijacking. The airline stated no emergency occurred and the aircraft and passengers were never at risk, with the incident caused by a technical error in the radio communication system.
