The Canadian Navy heads to the shores of British Columbia, where diver Sean Smyrichinsky has discovered an apparently lost nuclear bomb Mark 4. It went down on 13 February 1950 during a test flight of the Convair B-36 Peacemaker bomber. The missing five-ton bomb was lost in flight from Alaska when the machine crashed and three of its six engines caught fire.
