It is a matter of public record that French ATC speaking French to a French aircraft at a major international airport in France almost caused the death of hundreds of people.
Like it or not, and the history is irrelevant, English is the language of aviation and the sooner the French cease their xenophobic attitude towards all things English then the sooner the aviation world will be a safer place.
By all means insist on all things in France being French, but leave aviation to aviators who understand the importance of effective communication!
It's ignorant replies like this that make me shake my head. Did you ever bother reading the infamous "French ATC" thread? Did you ever fly to other countries, even in Europe? Did you ever look into the factors of your near-death scenarios? Your pet argument doesn't work at all, and besides the world is a tad bigger than your glance over to France with many countries and operations working in multi-lingual ATC environment. Latin America probably being the biggest dual-language ATC system.
What about leaving aviation to aviators who aren't so narrow-minded?
