Uncontained failure
Uncontained engine failures are rare, and the Trent is a mature design, which some carriers prefer to anything GE or Pratt.
This is a random event caused by either a manufacturing defect, or a maintenance error.
I am a fan of neither Airbus nor Rollers, since I own shares in both GE and Boeing.
However, I would not hesitate to fly in any Airbus, nor would I question either the reliablity or durability of any Rolls-Royce gas turbine.
A random event, in other words, not a systemic problem.
Anyway, the aircraft landed with no injuries to anyone, so even in a potentially bad situation, everything worked out well, as it is intended to.
Everything flight critical is either fail-safe or redundant, so the airplane landed, and everyone aboard walked away.
A happy ending, not the ragged edge of disaster portrayed by Katie and some ex-NTSB blimp I saw on the network news.
