I can't believe no one is talking about this here. Africa really is off the radar! 
Accident: SA Airlink RJ85 near Johannesburg on Nov 8th 2017, uncontained engine failure takes out two engines

They dont have an equivalent of the Daily Fail to create the usual "screaming passengers thought they were going to die" headlines so nobody noticed.
Double engine fail nicely handled by the crew, everyone walked away - well done.

Pictures in the article are recommended though. As their are more failures than good pictures.
The other article has comments from a pax (not a happy clapper). Gives you an idea about of required 'reassurance' for that category of passengers. Time for PRM - Passenger Reassurance Management?

I am SLF only so you might excuse my comment. Isn't it that pilots are trained for this kind of situation? So it is their job to bring the aircraft down to the ground safely. Nothing special for them....just saying

Engine failures are indeed trained quite often, although a non-contained failure like this can lead to multiple system failures if the fragments shatter something essential. Multiple failures (including multiple engine failures) are not trained as frequently. Simulator trained failures tend to be a bit more "clear-cut" than real life as simulator designers select specific malfunctions and try to implement them in a plausible way. "Real life" indications, sounds, vibrations may be different and some effects of shredded metal (like intense vibrations) are hard to simulate.
The basic chance for a pilot to experience an actual engine failure during his/her career is reportedly about 50:50, so the chance of experiencing something like this must be even less. Flying 4-engined airplanes increases the chance a bit, of course ;-)
So while the pilots who brought this wounded bird back safely just did their job they sure had their hands full and more than a good day's work set out for them. While we prepare for events like this during our whole pilot life, we're quite happy to finish our last flight having shut down engines on the ground only.

As the designer responsible for an uncontained engine failure (on the test bed) some 55 years ago, that was about the most exciting moment of my life.
To have a similar failure in a static aeroplane (pilot action irrelevant except to instruct an evac after the event) would be like playing Russian roulette.
To have such a failure in a moving/airborne plane is more like playing Russian roulette with a revolver with an unknown number of bullets loaded.
Skill plus luck required.

Direction of Failure
Is it just random chance that the failed Blades/Disc exited away from the Aircraft, rather than towards it? Would that have been worse? The shrapnel spray pattern on the outer engine cowling looks frightening....
There have been lots of data studies on uncontained failures against the variables versus occurrence. The design criteria is to minimize against catastrophic results and includes crew actions as part of the minimization.
So far I don't see anything in this event that is outside the study experience given that it was an uncontained event.

Re- flying on or returning. If the choice was return to Harare (Mugabeville) or going on the Jo'burg (more facilites, more stable}, I think the crew made right choice. Well done, crew!

Here below some pictures from HB-IXU, a Avro RJ-100 from Swiss in August 2004
Exactly the same story, uncontained engine failure of the engine No2
with debris hitting the engine No1
The aircraft was enroute from Amsterdam to Zurich and diverted to Francfort
