An Austrian Airlines Airbus A320-200, registration OE-LBM performing flight OS-434 from Palma Mallorca,SP (Spain) to Vienna (Austria), was descending through about FL200 about 60nm southsouthwest of Vienna when the aircraft encountered hail. The crew continued for a safe landing on Vienna's runway 11 about 20 minutes later.
Austria's Unwetterzentrale (UWZ) reported the aircraft had a "date" with a thunderstorm cell over Hartberg, Styria, in about 6000 meters of altitude. After a "blind flight" the aircraft landed safely.
The airline reported the aircraft entered a thunderstorm cell that was not visible on the weather radar. Both windshields, the nose/radome as well as several panels were damaged. The crew declared Mayday and continued for a safe landing. All on board remained uninjured.
