SS Edmund Fitzgerald (nicknamed "Mighty Fitz," "The Fitz," or "The Big Fitz") was an American Great Lakes freighter launched on June 8, 1958. Over 15,000 people attended the Fitzgerald's launch. The event was troublesome. When Mrs. Edmund Fitzgerald christened the boat by smashing a champagne bottle over the bow, it took her three swings to break the bottle. The launch was delayed 36 minutes while the shipyard crew struggled to release the keel blocks. Upon launching sideways into the water, the boat crashed violently into a dock.Although she had reported having some difficulties during a gale on Lake Superior, the Fitzgerald sank suddenly on November 10, 1975 in 530 feet of water without sending any distress signals. The precise cause of her sinking remains a mystery. All 29 on board were lost.
