If we're talking arrogance in flying then let's not forget the near ubiquitous use of French on the R/T by French airline pilots flying into CDG and their ATC colleagues, meaning all foreign airline pilots have not a clue what they are saying
As QDM says. I've always been amazed by the arrogance of French speaking controllers/pilots in busy controlled airspace (France, inc CDG etc, Canada and Africa) where use of exclusive use of French language between pilot & controller causes almost everyone else on frequency a loss of SA. Several reports of incidents at CDG refer to this as a cause but the language barrier remains.
