The comments from the lady passenger suggests that they sat in the aircraft about one and a half hours with very little assistance from the cabin crew (with such requests as water) and one PA announcement in incomprehensible English from the Captain. Lucky it wasn't such a serious event. I wonder what would have transpired if an emergency evacuation had been needed. Note that the flight was operated for a French carrier (in their livery) by a Greek registered a/c and obviously non French speaking crew.
