'Flying' submarines plumb hidden depths - BBC News

Two-thirds of the earth is underwater. We glide over the surface of the oceans, but we still have very little idea what is going on even a few metres down. We spend billions sending craft and people into space, but we do not really know what happens under the waves. One man who finds that more than curious is Graham Hawkes, a beneath-the-sea maverick who has been working on underwater craft for most of his life. It is a lonely, driven quest, relying rather dangerously on the engagement and backing of a few wealthy enthusiasts. Born in London, Mr Hawkes learnt his engineering expertise in the defence industry, working initially on torpedoes in Norfolk, England.
