A mysterious 30 meter long tank / silo / spacecraft part has washed ashore in Scotland. This sort of thing never seems to happen to me. I was at Ocean Beach in San Francisco twice in the last week, and all I found was some gelatinous blobs and a lot of bubbles.
The story on the BBC has all of the typically-British details.
I'm no expert, but it looks to me like an aluminum centrifuge tube, used for enriching Uranium for nuclear weapons.
