As unusual places to have lunch go, 100ft beneath the Firth of Clyde is pretty hard to beat. Yet to the officers in the wardroom of the Sovereign it all seems pretty unremarkable. I suppose that when you have breakfasted below the North Atlantic and dined under the Arctic pack ice a calm sea five miles off Largs is nothing to write home about.
This is a great DVD to get you started in submarines. The DVD initially gives you a brief (15 min) history of submarine development, highlighting all the important mile stones in the early development of the submarine.
The DVD then expands into providing a more detailed explanation of both the technological and historical development of the submarine, thus providing the viewer with a well balanced introductoin to submarines.
