On November 10, 1975, in the most famous shipwreck in Great Lakes history, the Edmund Fitzgerald sank in a treacherous storm on Lake Superior. Now in conjunction with its anniversary of the ship sinking, Southport Video Productions, a film company specializing in documentaries on shipwrecks and lighthouses, has released a program titled The Edmund Fitzgerald Controversy. “This is by far our most detailed and comprehensive look at this great ship’s story,” said Southport producer Mark C. Gumbinger of www.edmundfitzgerald.com, who produced and directed three earlier entries on the Edmund Fitzgerald. Thanks to the popular 1976 song by singer/songwriter Gordon Lightfoot, the story of the Edmund Fitzgerald has reached and maintained legendary status in Great Lakes maritime lore.
