The SS Edmund Fitzgerald was an American Great Lakes freighter that made headlines after sinking in a Lake Superior storm on November 10, 1975, with the loss of the entire crew of 29. When launched on June 8, 1958, she was the largest boat on North America`s Great Lakes, and she remains the largest boat to have sunk there. Nicknamed the "Mighty Fitz", "Fitz", or "Big Fitz", the ship suffered a series of mishaps during her launch: it took three attempts to break the champagne bottle used to christen her, and she collided with a pier when she entered the water.
