It is a Mexican airliner, if this plane fell out of the sky over Chicago, the people would be suing MEXICO, not the US.
Your funny. That's a real knee slapper.
They would blame Bush of course, and global warming for the inexplicable microburst that brought it down. And everyone knows global warming is humanity fault, but especially the US citizens fault (not illegal aliens, historically oppressed minority, you know).
But you'd be sued in an American court, because actions committed within the territory of the United States are subject to United States law. That the plane in question is the property of a corporation based outside of the United States is immaterial -- its owners are still subject to US law.
