A Greek military F4 Phantom jet crashed near Athens during an air show on Saturday afternoon, according to the Greek news agency Ana. The incident occurred at a military base near the capital during an annual event known as "Athens Flying Week," which attracts thousands of spectators. The exact cause of the crash is still unknown, and the fate of the two pilots on board remains unclear, as reported by several local media outlets. A search and rescue operation is currently underway, according to a Greek air force official speaking to Reuters. The aircraft had just taken off from Tanagra Airport during the air show when it suddenly lost altitude before crashing, according to a journalist from the public television channel ERT, who was on-site. Immediately after the crash, an explosion was seen in front of the large crowd of spectators who had gathered for the event. A column of black smoke rose from the crash site, and a fire-fighting helicopter was sent to the scene to help extinguish the resulting fire, as shown in footage from ERT. The black smoke was visible from several hundred meters away, and loudspeakers at the air base urged attendees to move away from the area for their safety. Defense Minister Nikos Dendias, who had planned to travel to Thessaloniki for the International Fair—an important event during the political season—canceled his trip to be at the accident site. The crash has drawn significant attention, with the military and emergency services working to determine what caused the incident and to locate the pilots. As the investigation continues, the focus remains on the safety of the air show and the broader implications for military aviation in Greece.
