The Edmund Fitzgerald made no distress call. During a Lake Superior storm on the night of November 10, 1975, the ship suddenly disappeared from radar, with no survivors left to tell the tale. What exactly happened out there? You'll learn what we know — and what we never will — about the circumstances surrounding the wreck of the Edmund Fitzgerald. Follow the vessel's last run across the lake, into the worst storm its experienced captain had ever seen. Hear from experts who debate what might have gone wrong for the ship to founder during a storm that spared a similar ship just 10 miles away.

Edmund Fitzgerald: 50 Years Under is produced by the Duluth News Tribune, a newspaper that covered the Fitz during its heyday and has remained close to this story ever since. Find features that go into even greater detail, with photos and video, at duluthnewstribune.com/edmundfitzgerald.
