The safety of the Sukhoi Superjet 100 has been called into question following last week’s crash landing in Moscow which killed 41 of the 78 people on board.

A Superjet 100, operated by Aeroflot, burst into flames at Sheremetyevo International Airport during an emergency landing. It had taken off from the same airport just minutes before, with reports suggesting lightning struck the aircraft during its ascent.

More than 50,000 have now signed a petition calling for the model to be grounded while an investigation into the crash takes place, but Russia’s transport minister, who heads the commission in charge of the inquiry, said for now he didn’t see any reason to do so.

This is a total mish mash of Fake News and Misinformation i.e. talk of lightning strike causing aircraft to return on fire ? Is fire visible on the video we have available, doesn't seem to be to me until just before the final "touchdown" but maybe I'm not looking in the right place ? Talk of lightning strike killing all Comms. - so how did the pilot advise that he was returning ? Did a lighting strike kill all the digital / data / electronic instrument presentations ( and any electrical locking of overhead lockers, if such a device is ever contemplated ? ) and leave the pilot to return to land overweight for the first time in his experience, with only basic standby, clockface type instruments that might have been totally alien to him, or maybe he was looking at an Instagram photo of his young child's latest Lego creation sent to him on his Smartphone, at the same time ?

I guess I'm just missing something, and why don't we all wait until Putin releases the data from the voice and data recorders - if he will ?

Sorry to be flippant in face of a real tragedy, but I'm getting a bit bored by it all now.

Meanwhile, here is a REAL lightning strike event, sadly.

UP respect for the addition of the new group - it present some interesting issues.

F3WMB and G-CPTN , I thought that a basic control before opening an aircraft door is to make sure there is no fire outside.
Or water, thinking of the Hudson landing.

llondel, you are right. I should have used the words obstacles / hazards.

Evacuation in a situation like this is usually in the wrong order for saving lives. I met a cadet officer (civilian teacher) on a Summer Camp who had been on the coach crash near Wittering about 15 years ago. The coach broke down, pulled onto the hard shoulder, and was then rear-ended by an 18 wheeler two minutes later. They were debussing front seats first and about halfway done. One cadet at the back died, and one was still in hospital 5 years later (likely forever). ....................
Thread drift. A lorry (left-hand drive) had pulled out of the Shell filling station station at Thornaugh causing the bus to swerve into the outside lane; the bus clipped the lorry as the driver tried to avoid a collision. The bus driver, as you say, pulled over onto the hard shoulder and was starting to de-plane the passengers when a lorry belonging to Rathbones Bakery struck the rear of the coach. The bus driver was subsequently prosecuted for causing death by dangerous driving and sentenced to twelve months imprisonment and banned for two years. The sentence was greeted with disbelief as the basis for the prosecution was that the bus driver should have carried on a further half mile along the A1 to a lay-by where she could have safely stopped - ( the question was asked "Isn't that leaving the scene of an accident?"). MOD strongly supported the driver all through the proceedings and on release, she was given her job back but confined to camp area only driving until her ban expired. A truly dreadful night for a group of very distressed cadets. The was a very sombre mood on the station for several days afterwards.

In addition to PanAm 214 there has been a total loss of an Iranian military Classic 747 stuck by lightning where the wing upper surface separated following the resultant fuel-air explosion.

That Iranian 747 was one of a pair of sisterships, with consecutive serial numbers, which were sold to the Imperial Iranian Air Force by TWA. The other one was sent back to TWA with a demand for a full refund. That other one also suffered a fuel tank explosion off the coast of Long Island as Flight 800.

The Report on the Iranian one was a whitewash by Boeing who did not want to admit that the Fuel Quantity Indication System's Kapton wiring was prone to cracking of the insulation and could produce a spark of sufficent energy to trigger a deflagration of the fumes in a fuel tank. They used some totally garbage eyewitness "evidence" to cover up the FQIS being responsible for the 'explosion'. The CVR clearly recorded one of the crew saying "we are in the soup", ie full IMC at the time of an electrical transient and therefore could not possibly have been seen by anyone on the ground at the time of the electrical spark in the FQIS wiring within a fuel tank. Sure, there had been a lightning strike on the airframe at some time in the recent past, but not on that flight.

For Boeing, the name of the game was to avoid a loss of public confidence in the 747 so they 'bigged up' the lightning story. Sadly, this led directly to the loss of TWA800 many years later. It too suffered a fuel fumes deflagration, but in the centre wing tank, not the No1 tank as happened to her sister. No lightning strike there either.

OK, DWail, but they must have got such detailed information form somewhere:
Horrifying new video shows Aeroflot jet bouncing along runway at the hands of pilots who 'couldn't land without autopilot' after lightning strike disabled electronics - before bursting into fireball killing 41

"The crash investigation is leaning towards 'pilot error' over the landing and leading Moscow experts now say an 'over-dependence on autopilot' on commercial flights is an issue that should be addressed by all major airlines."

The "'Air traffic control did help us, they guided us to the runway. The speed was not high, but normal for landing.
'Everything was according to the book. We gently approached the ground, slowing down."
(by the Captain) does not sound convincing, though, when you have seen the new footage of the landing (in the article).

Thanks, Probes - this video is much clearer.
The crash occurs on the 4th touchdown, and looks like a classic PIO such as one might get from a student in basic training. I stand by my hypothesis in post #28.

Fox.
I looked back at your #28 before posting, and I think you are right.

I'd just add, all this 'auto this, auto that' is great for normal ops.

If it all goes offline, me no care.

Others will be fugged.....

edit to add, maybe me fugged also......
