Tanagra, Greece: A Hellenic Air Force F-4E Phantom II crashed during the Athens Flying Week air show at Tanagra Air Base, north of Athens, on Saturday, September 5, 2026, killing both pilots on board. The accident occurred at 2:55 p.m. local time during the aircraft’s aerial display, with thousands of spectators watching from the air base. The aircraft crashed about three nautical miles southeast of the 114th Combat Wing, according to the Hellenic Air Force General Staff.
The aircraft was an F-4E Phantom II operated by the Hellenic Air Force’s 338 Squadron of the 117th Combat Wing. It was a twin-seat fighter, meaning two crew members were aboard. The Air Force later identified them as 40-year-old Squadron Leader Ioannis Blesias and 37-year-old Squadron Leader Dimitrios Petrou. Both were killed in the crash. Greek reports said the pilots did not have enough time to activate their ejection seats before impact.
The F-4 was participating in the flying programme of Athens Flying Week 2026 when it suddenly lost altitude during a low-level manoeuvre. Video and eyewitness accounts showed the fighter entering a low right-hand turn before rapidly descending and striking the ground. The impact produced a large explosion and fire, with debris scattered around the crash area. Reports said the aircraft had been airborne for only a few minutes before the accident.
The crash occurred outside the main spectator area and did not result in reported injuries among spectators or local residents. Greek broadcaster ERT, however, reported that two people were injured by fragments from the crash. The impact also started a significant fire that spread into nearby vegetation and forested areas. Firefighters, emergency vehicles, aircraft and helicopters were deployed to contain the blaze. Authorities also issued an emergency alert to people in the wider area and temporarily closed nearby roads as firefighting operations continued.
The remaining Athens Flying Week programme was cancelled following the accident, and spectators were directed away from the affected area. The air show, held at Tanagra on September 5 and 6, had attracted thousands of aviation enthusiasts and featured military and civilian aircraft from Greece and other countries.
The exact cause of the crash remains unknown. The Hellenic Air Force has appointed a special investigation committee to determine what caused the F-4E to lose altitude and why the crew could not recover the aircraft. Investigators are examining the wreckage, video recordings from the air show and spectators, and communications between the pilots and air traffic control. The availability of multiple recordings is expected to help investigators reconstruct the aircraft’s final moments.
The official Hellenic Air Force statement said: “On Saturday, September 5, 2026, at 14:55, an F-4E Phantom II aircraft of the 338 Squadron of the 117 Combat Wing, which was participating in the ‘Athens Flying Week 2026’ Airshow, crashed three nautical miles southeast of the 114 Combat Wing, resulting in the fatal injury of the two crew members.” It added that “the causes of the accident are being investigated by the competent committee of the Air Force.”
As of September 7, investigators had not publicly attributed the accident to a specific technical failure, pilot error, weather condition or other cause. Greek reporting has said investigators are examining possibilities including a bird strike or a mechanical problem during the manoeuvre, but neither has been established as the cause.
The crash prompted an immediate response from Greece’s defence leadership. Defence Minister Nikos Dendias cut short his programme in Thessaloniki and returned to Athens following news of the accident. The Ministry of National Defence declared three days of mourning across the Armed Forces, from September 5 through September 7, for the two airmen.
Greek Prime Minister Kyriakos Mitsotakis also addressed the tragedy, saying the incident had cast a shadow over the country’s events in Thessaloniki and expressing his thoughts for the families of the two pilots. He described their deaths as a reminder of “the daily risk” undertaken by military aviators.
The fatal accident has also renewed attention on Greece’s F-4 Phantom fleet. The F-4 Phantom II is a long-serving American-designed fighter that has been operated by Greece for decades, and the aircraft involved in the crash was being flown by the Hellenic Air Force as part of its Athens Flying Week display. However, there is currently no official finding linking the age or condition of the aircraft to the crash.
The investigation remains ongoing, and the final cause will depend on the examination of the wreckage, cockpit and control-tower communications, available flight footage and other evidence gathered from the crash site.
