Antonov An-124 Engine issue.

Did they not get the gear down? Looks like they lost quite a few other systems at a glance.
The video's of it landing show the gear to be down, but, it looks like they couldn't slow it down for some reason, so either no reverse thrust on the 3 donks left, or a problem with the brakes, which is why it ended up going off the end of the runway and rippping the nose gear off?Crikey, definitely brown trousers time.
This is what came down in a warehouse a couple of miles away:

This is what the pilot said shortly after the accident:
(https://t.me/bazabazon/5163)
The second engine exploded and cut electric wires, so we lost all the electricity. And we returned to the aerodrome of departure on an airplane having a total electric failure. We lost all the communication, both intra-cockpit and with the ATC. We just gained 300m altitude at that point. We were a crew of 6, and other technical crew of 8, they were in the rear cabin. We took a decision to return to the aerodrome of departure, visually, we tried to establish visual communication but that didn’t work. We took a decision to land on RWY25, since it was a critical situation and we took a decision to land as soon as possible. Since we didn’t have a lot of altitude and excess of thrust too. There was a complete electric failure, brakes didn’t work, reverse didn’t work either since the wires were cut. The landing was soft, there was no damage during the touchdown, all the damage was due to the runway excursion. The gauges in the cockpit didn’t work, from the angle of attack we figured out the speed was about 280, it was a calculated airspeed. We haven’t even raised the flaps at that time, just raised the gears and we heard a bang. We still had control, but the electrical system failed completely.
AVHerald have some good pictures showing how far it kept going: https://avherald.com/h?article=4df212c7(https://t.me/bazabazon/5163)

I'll take a look a the video. Sounds bad. Landing distance assumptions normally take no account of reverse thrust so that shouldn't be an issue. Possibly it forced an overweight landing onto an unsuitable length runway due to the 'catastrophic' nature of the failure. Looks a horrible one to deal with. ETA i see it's Novosibirsk. Pretty decent airfield. We used to consider that one of the best bets in that part of the world. Edited by Mabbs9 on Friday 13th November 18:34

At the 1988 Farnborough Air Show, an An124 blew an engine just as it started its take-off roll. It was able to stop on the runway.
Bit of a difference......much less speed, working brakes and working reverse thrust.....so not really a surprise they could stop on the runway.The opposite of what happened in Russia (add the weather conditions in Russia as well)

The plane was much younger too in 1988. The actual fault may have been the same but the engine incident happened much earlier in the take off run in the 1988 incident which is what allowed them to slow down and stop. They'd hardly started to move when the engine went bang.The opposite of what happened in Russia (add the weather conditions in Russia as well)

An interesting aspect of the 1988 incident was that the Russians flew in a replacement engine on an Antonov An-22 - which nearly had an accident when it was landing (he managed to land with one set of mainwheels on the grass). Watch this for a lunatic approach.

WTF is that all about? 
The short runway at Farnborough (normally used by light aircraft and the RAE Gliding Club) is no longer in use.

The story is that, due to poor command of English, he misunderstood the instructions from Farnborough Approach and initially started lining up with the short runway at Farnborough. He then did a last minute correction to line up with the proper runway.

I used to glide at Farnborough in the early 1980s, and used all the runways there at the time. That approach doesn't line up with any of the runways, not even the arrester runway. The short runway at Farnborough (normally used by light aircraft and the RAE Gliding Club) is no longer in use.
Bizarre as it may seem, it looks almost as if the pilot had been instructed to do a downwind landing (away from the town in the event of an over-run), and the crabbed approach was to maximise the usable length of the main runway available to him. He certainly seems to be drifting down the runway even when banked away from it.
The other possibility is that as the normal approach is over higher ground, he could keep the threshold in sight by coming in at an angle, again maximise the available runway length.
As I recall, at the time, Russia was doing everything it could to avoid spending abroad, so the aircraft may have had most, if not all, of the fuel on board for the return journey.
Volga-Dnepr has now grounded its entire AN-124 fleet.
