I still don't understand why most countries speaks English to even their own country men, although it's not their natural language.
The whole Scandinavia, Germany, etc it's all the same. And it keeps everyone in the same picture.
To be honest, it's annoying having Atc controllers mixing languages when it's busy, keeps you blind and deaf. And that's how accidents occur...
So I guess there will never be a change unless another accident happens huh. Same story, never that someone will be proactive.
