Turbine blade failures are something which simply has to be accepted as a statistical likelihood. They're going to happen, because we're building machines that push materials and physics to the limits of endurance.

If you're uncomfortable with it, don't step in a machine that relies on something rotating at 20k rpm.

Most aircraft can only maintain takeoff thrust for a few minutes, because the engines are only rated to handle that temperature FOR A SPECIFIC SPAN OF TIME, after which you are entering "engine rich exhaust" territory. And if a blade happens to have an undetected fracture anyway, well...

Boom.
