Franklin expedition ship found by Canada

One of the two warships that; disappeared from in the Arctic's Northwest passage in 1845 has been found by Canada.

It is either the HMS Erebus or the HMS Terror.

The sailors, handpicked by explorer Sir John Franklin, are rumoured to have resorted to cannibalism.

Canada restarted the search for the ships in as part of its mission to assert sovereignty over the Northwest Passage.

Prime Minister Stephen Harper described the find as "truly a historic moment for Canada".
