The press report, as usual, doesn't make clear exactly what happened. Maybe more information will emerge. Meanwhile, in view of other incidents, one does wonder whether another heavy - maybe an A380 - passed above them?

What I gathered from the story. CAT one hour out from landing. The seatbelt sign was off, PAX who were injured did not have their seatbelt on.

Here is the FR24 plot:
https://www.flightradar24.com/data/f...su270/#d3c81af
And the FlightAware plot:
https://flightaware.com/live/flight/.../VTBS/tracklog
On the track logs from both sources an event is visible at about 2355Z. The plane is about to cross the coast of Burma at FL350.
A first glance at the FR24 data shows the altitude climb by about 700 feet and then return to FL350. Groundspeed drops to 492 knots and rises to 522 knots. Vertical speed fluctuates between 1300 fpm down and 2000 up. The event seems to last perhaps two minutes before things stabilize prior to starting down for landing. Usual disclaimers about hobbyist ADS-B data apply.
The closest A380 I see is EK374 DXB-BKK at FL 390. But it's about 150 miles ahead and its track to BKK is well to the west of SU270's position.

Reputable sources are concurring that they did indeed penetrate the very worst part of CB, which reached 14,000 feet above them while they were in it. Apparently they did attempt to deviate so why this occurred is known only by the crew.

Another passenger called Katya said: 'The sky was clear, no single cloud.... And all of a sudden - one blow. Then another. People were simply hurled out of their seats. Many were thrown into the aisle.'
'The pilot has more than 23 thousand flight hours, and the co-pilot has over 10,500 flight hours.
'However, the turbulence that hit the Boeing 777 was impossible to foresee.
'The incident was caused by what is known in aviation as 'clear-air turbulence'.
'Such turbulence occurs without any clouds, in clear skies with good visibility, and weather radar is unable to alert of its approach. In such situations, the crew is unable to warn passengers of the need to return to their seats.'

Looking at the F24 replay, the two flights in front of it on the same track both took diversions in the exact area where it happened, so it seems fairly clear this was likely a CB. The aeroflot does seem to have begun a diversion, but obviously not by enough and they obviously hugely underestimated the ferocity of the weather they were flying through if they didn't put seatbelt signs on.

Possible, it'd be interesting to see a satellite of the area if it can be accessed anywhere?
I have some scepticism about passenger accounts that immediately describe the weather situation, seems a bit unusual to me. Especially after having spoken to Russian authorities...
Also rather disappointed to see the captain mentioning pax not wearing seatbelts being injured as if it was their fault. Highly unprofessional. Seems to be there's an effort to create a narrative here.

Article on Aviation Herald suggests Russian crews don't use the weather radar as they fear it will irradiate their man hoods

Taken from this tweet. Quite clearly shows some attempt at deviation..apparently not successful.

Thanks! So they were in clear air...right up until the moment they weren't and they punched into the storm. It doesn't even look like there were a lot of cloud layers around to make seeing and avoiding difficult. All very strange.
