Captain Speaking: "Good morning ladies and gentlemen. We are now at our cruising altitude of 31,000ft and we will be flying west across the Ionian Sea, and then up the east coast of Italy, across the Alps into Switzerland, and then starting to descend over France before landing at we won't (rustle of papers). Oh my God, this is the wrong flight plan! Sorry. Up the west coast of Italy, then into Switzerland."
