I heard on the ABC network that the problem was a vibration in the tail.
NOW, who knows what the heck that really means, but I'll tell you this if you land in bumb frick, it must have been of great concern.
I'm sure many of you remember the egyptair 767 crash in which suicide was the probable cause. But some said there was something wrong with the elevator of this type.
So, something to think about.
BUT if you have something you don't want to cross the atlantic with, but don't mind flying an hour to a decent place for your passengers that is one thing. BUT an immediate landing where things are not great must mean something big.
