Where did this "catastrophic engine failure" come from?
I had a little wander around said a/c today, no sign of a fire, no big holes in the nacelle. All very civilised really.
The reason it all went pear shaped on the ground is because at the busiest hour of the day they closed a runway! Couple that with the work in progress on the taxiway and you have a right royal mess.
Well done to all concerned, no one died not even a Heron/Crow etc etc etc.....
