If any incident or accident directly related to this would have happened before, then we would all be speaking english mate!
You mean like the incident at Paris a few years ago when the English crew of a Shorts 360 started to line up for departure at an intermediate point (after being told do so by the controller), unaware that an aircraft had been cleared for take-off,
in French, from full length? I also have a playback of a BA crew told to cross an active runway at LFPG who almost get taken out by an Air France aircraft on the take-off roll. What was ironic about that one, was that the controller, when he realised what was happening, told the BA crew to expedite their crossing in English, and told the Air France crew to abort take-off in French! So the BA crew were still none the wiser as to what had almost happened!
