And there goes another Progress D-18T... I wonder if the CF6 retrofit will eventually happen...

Very well done by the crew - does anyone know if there was freight in this flight ?

Interestingly, posted 23/03/2020:

"Ukrainian authorities have ordered Antonov An-124 operators to inspect engines on the type after an uncontained powerplant failure."
"The directive, which takes effect from 25 March..."

SLF attorney here, but still able to see fabulous piloting performance by crew.
Waiting for report from algorithm writers of fidelity-to-reality rating of test algorithm running onboard the aircraft; I'm sure its truthfulness to what actually was performed by the crew was, what, close to 98.6 percent?

Did I see a couple of ejections after it hit the snow?

Hat, coat...

They were working on a new version AN-124 with CF6-80C2 engines, but I don't know if that's on on-going program. Awfully quiet if it is still happening.
I never heard of a planned retrofit, although if it did happen for new production it would make the engineering for a retrofit quite a bit easier.

Well done Captain, that was not even a sim scenario case.Wife and children will be happy to see you safe and healthy.

The CF6 has had issues with uncontained engine failures, though I think it may be on the -50 series. HP2 turbine wheel IIRC.

I bet the guy filming from the apron had an Airplane moment: "OMG he's coming right at me!!"

Sim Instructor:

"So immediately after take off we're going to lose Number 2 engine, Freeze Number 1 at 70%, fail all electrics and power, take out the instrument panel and all the comms - ready?"

So, he takes off, doesn’t get very high and circles back to the Airfield – all in Radio silence. Those in the tower have a terrific view of him coming round, landing and running into the overshoot.
Am I missing something or have they photo-shopped out all the emergency services chasing after this Aircraft during a very non-standard approach and landing?

morton, all ATC knew was that they had lost radio contact. You don't call out the emergency vehicles for comm failure. Could they see any damage on the a/c? I doubt it.

He is going kind of fast for emergency vehicles to catch up and there is some question as to how stable he may remain. The real issue is how long it took to catch him at the end and what conditions did he state to the tower..

I was in one of these emergency vehicles once when a large transport was returning with a structural emergency, undefined, other than the pilots wanted to be on the ground immediately, We shut down all air operations until he rolled out and we chased him down the runway, probably a mile behind intending on catching him when he came to a stop

Just to introduce a bit of levity into what is going to be a long "why didn't he do this or that" from people who have mostly never been near an aeroplane but think that they know everything.

When I got near my first Argosy in 1962 I can vividly remember thinking during the external walkaround that if I had ever had to put it on the ground with the gear up then there was a lot of fuselage underneath me to be ground away before the family jewels were in peril.

When I got near my first Belfast in 1972, I came to the immediate conclusion that the future of my family was in even better shape.

How was I to know that Antonov had designed an even better solution?

The crew did well - very well.

I know for fact that is was considered for the Volga-Dnepr fleet but I guess it turned out to be too expensive / complex. Yet, they, just as Antonov or the Russian Air Force have to find a way to make those Progress D-18T last (and there is already some serious canibalism going on...). Don't know what will be the eventual outcome but something has to give...

One imagines the seat cushions are no longer servicable.
Epic job be the crew for getting her back on the ground, espercially without injuries.

Right - the CF6-50 has had a number of issues with uncontained turbine disc failures (with a number of AD's to manage it). The CF6-80A also had a couple pretty spectacular turbine disc failures.
Off hand, I can't think of any uncontained failure issues with the -80C series.

Pistonprop - Radio silence was only one aspect. I thought the low circle back after take off and abnormal approach might have been an indicator of things not going too well.
