A Corendon Airlines Boeing 737-800 was escorted into Nuremberg Airport by German Air Force fighter jets on October 13 after a suspected hijacking alert triggered an emergency response and a temporary suspension of airport operations.

Flight XR456, operating from Corfu, Greece, to Nuremberg in southern Germany, transmitted transponder code 7500 while flying over Croatian airspace before experiencing a loss of radio contact with air traffic control.

Flight XR456 Incident Timeline

  • 1Corendon flight XR456 transmitted transponder code 7500 over Croatian airspace.
  • 2A loss of radio contact between the cockpit and air traffic control triggered emergency procedures.
  • 3Two Eurofighter Typhoon fighter jets were scrambled from Neuburg Air Base to intercept and escort the aircraft.
  • 4The aircraft landed safely at Nuremberg Airport, where police confirmed no danger existed and attributed the signal to a radio malfunction.

Why Was a Military Escort Deployed?

The military response reflected the seriousness of the information available to authorities at the time. When a transponder code 7500 is transmitted alongside an inability to establish radio contact, controllers must treat the situation as a potential hijacking rather than assuming a technical failure.

Corendon Airlines later confirmed the alert was caused by a brief malfunction in its radio communication system. The airline emphasized that passengers, crew, and the aircraft were never in danger during the flight.

Nuremberg Operational Disruption

Police secured parts of Nuremberg Airport while emergency teams prepared for the aircraft’s arrival. Operations were temporarily suspended, resulting in six delayed flights and two incoming flights diverted to neighboring airports before normal operations resumed.

Separate Drone Reports

The emergency unfolded while Nuremberg Airport was already investigating separate reports from three pilots who spotted an unidentified object overnight. A helicopter search found no drone, and authorities treat this as unrelated to the Corendon radio issue.

Understanding Aviation Threat Protocols

Germany maintains quick-reaction fighter units to investigate airborne threats. According to the German Air Force, incidents involving lost communication with civilian aircraft trigger fighter deployments approximately once or twice a month.

A military intercept is designed to establish visual contact and assist authorities when communication fails. Crucial indicators include:

Transponder Code 7500 (Hijack) Loss of Radio Contact (COMLOSS) Quick Reaction Intercept

Aviation Security & System Reliability

While the flight landed safely and without injury, the event highlights the operational sensitivity of European aviation infrastructure during heightened security concerns across German airports.

  • Dependable communication systems remain vital to avoiding unnecessary military intercepts and airport shutdowns.
  • Air traffic management and security agencies must act on potential threat indications immediately until safety can be visually verified.

Frequently Asked Questions (FAQ)


The Corendon Airlines Boeing 737-800 transmitted transponder code 7500 and lost radio contact while en route from Corfu to Nuremberg, prompting an emergency response and a military fighter jet escort.

Transponder code 7500 is an international emergency squawk code signaling a suspected hijacking or unlawful interference on board an aircraft.

No. Corendon Airlines confirmed there was no genuine emergency or hijacking. The alert was caused by a temporary malfunction in the cockpit's radio communication system.

Because the hijacking code was transmitted alongside a loss of radio communication, authorities were obligated to treat the situation as a potential threat and scramble two Eurofighter Typhoons to visually monitor the plane.

The Boeing 737-800 landed safely at Nuremberg Airport shortly after noon local time under police supervision.

Airport operations were temporarily suspended. As a result, six flights were delayed and two inbound flights were diverted before normal operations resumed.

There is no evidence connecting the overnight drone reports near Nuremberg Airport to Corendon's radio malfunction; authorities treat them as separate events.

According to the German Air Force, quick-reaction fighter deployments due to lost radio contact with civilian aircraft occur approximately once or twice a month.

No injuries or security threats were reported. All passengers, crew, and the aircraft remained safe throughout the flight.

Police conducted thorough safety checks, confirmed there was no danger, gave the all-clear, and Corendon Airlines initiated an investigation into the radio malfunction.
