I have worked motors that bad. all stages had to be replaced. most of the time the engine is a total wrightoff. would like to know the storie behind that photo.
I don't know what caused the damage (looks like FOD), but the way I heard it, it was a China Airlines 747 being ferried that way. They had put the seat belts on to keep it from windmilling. It landed in Frankfort for fuel and the German authorities wandered over and inspected the airplane and ended up making them change 2 of the engines before they would let them depart.
