Hungary launched fighter jets Thursday after an Israeli Arkia passenger plane failed to respond to ground control communications. The incident triggered NATO’s highest level of alert, according to Hungarian Prime Minister Viktor Orbán. Hungarian authorities lost contact with the aircraft while it was flying over Hungarian airspace. The jets successfully located the plane visually, and subsequently established communication between the Arkia pilots and local air traffic officials. The situation was resolved without further incident, and the plane continued its journey. Details surrounding the initial communication failure remain unclear.
