The title of this article was the signal sent by William Anderson, commanding officer of USS Nautilus, the world's first nuclear-powered submarine, upon completion of Operation Sunshine - the first submerged crossing of the Arctic Ocean beneath the polar ice-cap. It told his superiors back in the USA that the ship had successfully passed beneath the North Pole. He later gave his book about the operation the same title.
The operation made history in many ways, as well as being a triumphant demonstration of US naval technological capabilities. I was fascinated by it as a youngster, reading Cdr. Anderson's book and many others dealing with it.
I recently came across this video clip about Operation Sunshine on YouTube, and thought you might enjoy it as much as I did.
