Very worrying that a state of the art engine - and a new one at that - could have suffered such a serious uncontained failure.
I wonder if this will be attributed to a fundamental design error - perhaps related in some way to the problems besetting the Trent 1000 programme on the B787?
I am sure the folks in Derby are scrutinising both incidents to identify possible common factors such as material batch and core design features. Best of luck to them.
