Likewise the only widebody manufacturer never to have had a passenger fatality on one of their large aircraft is ... Ilyushin.

Not quite true. I was in Luxemburg in 1982 and a IL-62 crashed there , there were fatalities .
Google found this to refresh my memory : https://en.wikipedia.org/wiki/Aeroflot_Flight_343 in fact the accident was a bit similar to this SSJ one .
There also have a been a couple in East Germany times in the 70s..
and of course if you include IL-76s that is totally another statistic

To apologise for OT on another say day in aviation

But this hand baggage issue is all of the airlines own making - they blatantly offer CBO only fares and then everyone moans then there is too much hand and wheeled sized luggage brought on board.

The answer is simple - stop the CBO fares - Only allow one small piece like before, that must be able to fit under your seat, (even new A350's in Y have no centre overhead bins)
(and maybe also allow a ladies handbag or a laptop/man bag/duty frees)

I had this other idea for long time, wonder what the comments here would be. The OVHD bins on my A/C have a manufacturer's max loading limit. I presume from crashworthiness anyway. So how about we divide the number of racks times loading by the number of passenger seats and make a weight rule for onboard luggage? Small items (purses, cameras, laptops) and dutyfree to go under the seats. I think the overall amount of items carried would be about half.

Sad case for all, RIP.
If reporting is at all correct TR Code 7600 (comms failure) after lightening strike.
Now whilst this is inconvenient it does not necessitate a rapid immediate return.
So probably a lot more going on.
If the Flight control computers were affected this would have compromised the normal fly by wire systems and may have left the crew with degraded flight control.
This may go some way to explaining the Heavy Landing / Poor bounce recovery technique that resulted in the loss of main UC and resultant fire.
Some of my colleagues in a previous life had the pleasure of training Russian pilots on the B757, and whilst certain aspects of the training was 'challenging' the aircraft handling near the ground was generally very good.
Lets hope the inquiry comes up with the answers without politics getting in the way.

For pities sake 7500 is unlawful interference, not comms failure.

Easy way to remember:
75 taken alive
76 technical glitch
77 go to heaven

posted by FlightDetentmake a weight rule for onboard luggage?
Many flights used to enforce a 7kg limit. Years back I flew from PER to CCK and my carry on was weighed at 7.5 kg. I was told to take the Sunday newspaper out of the bag and carry it under my arm, as that would be OK!

I believe that the Il-62 was single aisle, thus not considered a widebody.

According to Interfax citing the captain of SU1492, after a lightning strike the FBW system switched to direct law.
"командир экипажа Денис Евдокимов сообщил: 'Из-за молнии у нас произошла потеря радиосвязи и переход самолета не через компьютер, а напрямую - на аварийный режим управления' "

No, one would not. It is a certification requirement that this does not happen in a survivable accident see FAR/CS 25.963 (d)
https://www.easa.europa.eu/sites/def...nt%2021%29.pdf
The BA38 crash would have be a different story if the B777 had not met theis requirement better. Its tanks dd of course have far less fuel in them, but there was no significant leakage.

Thruster763, the SSJ was certified to EASA standards, so on paper at least it met those same requirements.

As we currently have no idea what the impact load was it is impossible to speculate on another types ability to survive the same.

Having experienced a cabin free of baggage on a flight, I can say it hastened loading and unloading of SLF and was altogether a pleasant experience. Sadly this experience was as a result of 9/11.

I was booked on the first flight out of LGW on 9/12 and check-in staff had no idea what to do, and delayed check in whilst a decision was made. The instruction was given 'no cabin baggage except passports and essential medication'.

100 pax opening hold bags to stuff in hand baggage in a check-in queue was a mess, but it happened. The resulting flight was comfortable with no one getting up to access lockers, and disembarkation was swift.

I for one would like to see a 'no cabin baggage' rule, or at least an enforced maximum of 12 x 12 x 6 inches or a foreign equivalent.
I, for one, will not entrust my laptop to hold baggage. I've seen loaders (I used to be a dispatcher). So this will never happen. If you have any baggage in the cabin, people will try to take it with them, even with flames and smoke in the cabin. So limiting size does very little to change behaviour.

And being just 30 seconds behind, if there had been a fire, the foam cannon would have started before they arrived. Look at the video today, foam everywhere but on the fire for at least 30 seconds.

"If you have any baggage in the cabin, people will try to take it with them, even with flames and smoke in the cabin. So limiting size does very little to change behaviour."

Quite right but I wonder if the aim should be not to forbid luggage in the cabin per se, but to make sure that the habit of people to take it with them doesn't involve their standing in the aisle to do so, or having to wheel it out, thus significantly obstructing other people's egress.

So if it can't be stowed overhead (the idea of not having passenger lockers) and is small enough not to be an obstacle in itself (forbidding larger wheeled cases, or anything that can't fit under a seat) then any time and obstruction involved in retrieving it prior to departing the plane will be minimised.
