Varied comments above about whether we "are trained" for such an event, or not

So most posters posing the question are not Professional Pilots I suspect

The
article / original post states
Some of the right engine fan blades had large chunks taken out. The left engine had many fan blades damaged at midway along the blade leading edge
However, we have no indication of the symptons / indications to the Flt Crew.
I can assure the readers, that I as an Airline Capt with an "EU Major", on twin jets, do
not train for such a scenario. We train for either a single engine failure (a lot!), or occasionally for an "at altitude" double engine failure. We do not have a scenario where 1 engine is dead, and the other half dead etc.
Maybe other airlines do, but the scenario related to seems "out of the book". I am sure the crew, if presented with multiple engine problems, dealt with it well. However, to say they were "trained for this (specific) situation" seems somewhat unlikely
