Four confirmed dead in Moscow air crash
 

We've all seen/heard about the TU-204 this morning, and condolences to those (mainly from the Csech Republic) whom have died...

HERE is some footage from the motorway where it overran onto...

HERE is the story, UK papers

That footage is chilling- the occupants in the car were very lucky.

If that big ditch wasn't beside the motorway....

Brake problems suspected
 

Initial reports are suggesting brake problems. Is it possible that the a/c was so underweight (no pax or freight) that the tyres couldn't get the assumed grip in the slippery conditions? Perhaps the unusually low weight led to an incorrect autobrake setting?

Not really, Philip.

The landing autobrake setting is selected based on a combination of weight, elevation, wind, slope, temperature deviation and thrust reverser/s for a given runway length.

For a given autobrake setting, the system will apply a pre-determined brake energy setting to provide a particular deceleration rate.

The antiskid system should always prevent the brakes from locking (regardless of autobrake setting), based on the traction (or lack thereof) of the individual wheels.

The pilots always have the option of using maximum manual braking, which firstly disengages the autobrake, but will apply maximum brake energy (with antiskid).

The question you need to ask is whether the runway was contaminated (snow/slush/ice). This will increase your landing distance significantly.

I bet this was a factor, Philip.

Reverse thrust?
 

Maybe a replay of QF1-Bangkok where reverse thrust was overlooked. Or inoperative?

Maybe a case of wait for the investigation and see?

But then we'll know!
 

No point speculating then, Nige! :)

If you notice notice carefully in the footage the nose wheel hits the car in front of the car filming and the filming car hits a row of seats.

Rip

QF1 was a bit more than just overlooking reverse thrust Philip. A combination of factors occurred that created that incident.
