"And on the topic of the Lufthansa A380, I recall reading they shut an engine down in theirs due to an oil issue in the last few months."

Lufthansa A380 engine shut down during flight
German airline Lufthansa said pilots on an Airbus A380 flying from Tokyo to Frankfurt shut down one of the superjumbo's four engines as it neared its destination.
Flight crew detected a change in oil pressure which was probably the result of dirt particles clogging a filter in the hydraulic circulation system, Lufthansa said. The engine was exchanged and the plane resumed service to the Japanese capital.
"It wasn't necessary to shut down the engine, but once in a while pilots do this just to be careful," Lufthansa spokesman Michael Lamberty said today by telephone. "Thankfully it happened just before landing. In another phase of the flight they may have been forced to perform an emergency landing."
