A Qatar Airways Airbus A330-200, registration A7-ACF performing flight QR-18 from London Heathrow,EN (UK) to Doha (Qatar), was enroute at FL390 enroute from Czech into Slovakian air space when the crew failed to establish contact with Slovakia's Air Traffic Control. Two Mig-29s were dispatched to intercept and visually identify the A330, radio communication was re-established thereafter and the flight continued to Doha for a safe landing about 4.5 hours later.
Slovakia's Air Force confirmed two MIG-29s intercepted a Qatar Airways Airbus A330 from London to Doha on Saturday (Oct 22nd).
May seem like a regular incident, nothing important. Just see those pics. Honestly, if you were a window passenger, what would your reaction be?!?!?
