Sorry, I should have been more clear: That was a reference to the A330 Dragonair failure of a Trent 700, blamed on faulty lubrication systems which resulted in insufficient oil getting where it should be, hence the temperature rise. The point was, while all in-flight shutdowns are serious, possibly the most serious type of event involves fan blade failures... It's bad enough to lose an engine without bits of the engine whizzing around the rest of the airframe (c.f. Sioux City...) Malc.
