Vueling Airlines flight VY-8549 was intercepted by two Czech Gripen fighter jets on May 27th.
The Airbus A320-200, en-route from Helsinki, Finland, to Barcelona, Spain, was about to enter Czech Airspace, however, the crew did not establish contact with Czech Air Traffic Control. Two Gripen fighter jets were therefore dispatched that contacted the flight on emergency frequency.
The communication was restored around 15 minutes after the plane entered Czech Airspace.
