To be really honest, when this much of an engine lets go survivability is always going to be largely down to luck.
So true. But engineers did a lot to raise the odds of survival.
How about 747-200F, ie. El-Al, Amsterdam. Major engine (mounting) failure took out adjacent engine and hydraulics and damaged wing including slats - that last being fatal.
According to the accident report, pilots lost control returning to the airport. It
might have been survivable otherwise.
In this respect the Qantas crew did a good job in getting a plane in a very bad shape back on the ground safely. Planes in better shape than the A380 have been lost.
