Eva San - what has the popularity of Mandarin got to do with the argument? It's about safety not quoting Moliere etc. Grow up and take part in the debate sensibly.
Pouvez-vous fournir un argument bien raisonné ? (William Shakespeare)
No - I didn't think so!
I partly agree that the popularity of Mandarin has nothing to do with your debate. But that was exactly the point of my answer to Widger...
First I'm not quoting Molière ( "la langue de Molière" is a common expression to say french language), second I'm just saying that the popularity of French as a language has nothing to do with the argument ( which was Widger's childish way of underlining the so-called Gallic Pride of the frenchs). It's only a matter of being an Icao language or not ...
So, sorry but I don't need to grow up !
And now, if everybody here agrees that there should be one and only one aviation language for safety reasons, then I say that it should be Chinese, because it's the most spoken language in the world ! And that's a sensible argument...
