I suspect this may be the media latching on to a fairly mundane event.
Not wishing to be picky but I consider a mundane event to be when I get on a scheduled flight and get off at the other end without anything going wrong.
The presumably rather experienced crew of this aircraft decided to shut down and engine and land as soon as practicably possible. That isn't a normal event no matter how blasé one wishes to appear about it. This, on a fairly new aircraft type which appears to have a bit of "previous" when it comes to unscheduled stops - particularly with this airline.
I am not in any way an apologist for some of the hyperbole appearing in the media but in fairness, I would say this event was fairly reported by the Beeb.
