Disasters at Sea S03E01 - Snapped in Two

Bulk carrier MV Flare is more than halfway on a 3,700-mile voyage across the North Atlantic to pick up a cargo of grain in Montreal. It never arrives. The massive ship gets caught in a violent storm and snaps in two. Miraculously, four of the crew of 25 survive, but the catastrophe greatly troubles investigators. The Flare is one of many active bulk carriers made of the same fracture-resistant steel. If there's a flaw in the design of the material, similar vessels all over the world may be in danger of sinking at any moment.
