Flygsäkerheten i Ryssland är ett skämt.
Skulle vara en mardröm att tvingas åka ryskt inrikesflyg.
Rosaviatsia (Russia's Civil Aviation Authority) reported, that due to environmental conditions the aircraft was to be de-iced before departure, ground staff however did not perform de-icing and the flight crew did not insist on de-icing being done.
