This failure was at a point in the flight that is NOT peak power for the engine. The aircraft was at altitude and cruising.

Failure rate on these is remarkably low considering the stress, temperatures and loads involved. And then between various model engines, some have better track records.

So if they had been at full power, would the the outcome have been much more serious? The ring was suppose to contain that blade. Wait..just read that the engine on a 737 use to have 24 blades. They now have 18.

Its seems that the ring should be inspected often because of their importance. I would know this with my zero knowledge

And, of course, turbines run more efficiently at very low temperatures. 30K feet is mighty cold.
