UK Government X-files have been released.
In them one can read that the top secret MoD Department, was in 1989 investigating the claims by a Norwich-based woman that she had had a conversation with an alien. She described the alien as having a Scandinavian accent. What the Government Department concluded did not follow the story, but I think we can be pretty certain that "the alien" was in fact a drunk Dane. It's an easy mistake to make.
