The Aviation Herald is reporting:
A Lufthansa Airbus A340-300, registration D-AIFD performing flight LH-598 from Frankfurt/Main (Germany) to Addis Ababa (Ethiopia), was enroute at FL350 near Dubrovnik (Croatia) when the crew reported engine trouble and diverted to Dubrovnik for a safe landing.
Passengers reported that the crew actually shut down two of the four engines.
There must be a very good reason why a 4-engine, long range aircraft would divert to somewhere like Dubrovnik while being so close (in relative terms) to its home base. Any truth to the passengers' take that this was a double engine failure?
