Seems like everyone has an opinion on this one!!
Can't believe that the CDG is still operating English/French combo dialect especially after the collision a few years back.
ICAO are mandating minimum English speaking requirements. Not sure of the implementation date but it fairly soon (before 2008 I recall).
I remember a safety specialist from Europe visiting Australia and in particular was interested in Australia's Safety Management System. He seemed impressed with the level of reporting and the fact that Australian controllers (generally) put their hand up if they have an operational error. He acknowledged that most errors went unreported and further that as a safety specialist "what can I do? I am only one man"!
