Boohoo Moose, the thing is that you, among others, still don't quite get it do you! If US airlines want to declare "an emergency" when flying in the USA so be it. DAL was not flying in the USA but was in a foreign country whose national language is not English. Hence the need to adhere to international standards. Here we have a Russian airline flying a domestic sector inside Russia. They can say whatever their training dictates and no doubt it will be in Russian.
