an important thing that would make the difference is if there was an ils available, at sochi airport in that condition would make the difference let's see ,they crash 4 miles out the rwy, so at that distance supposing an ils approach they schould be at more or less 1800 agl, my question; is possible that a microburst make the a320 lose that altitde in short final with the engine spooling fast in landing config, and since how long ago this company is operating an airbus fleet because to me this disaster smell of airbus mismatch for the pilots.
Condolences to all the affected
