Lost WWII submarine HMS Triumph found by diver.

Greek diver Kostas Thoctarides has found the wreck of the British submarine HMS Triumph, which disappeared during a World War II mission in 1942. The submarine was located at a depth of 670 feet in the Aegean Sea after a 25-year search. Thoctarides said the Triumph marked the fifth submarine he has found off the coast of Greece. The cause of the explosion that sank the submarine is still unclear.
