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...)
