The History Channel doc was "Deep Sea Detectives: The Death of the Edmund Fitzgerald", but this linked to site is the Great Lakes Shipwreck Museum store. They have others too, including "The Wreck of the Edmund Fitzgerald", another hour long doc.

And if you would like a chance to win a cruise on a real iron ore ship like the Fitz, buy your chance here.

Not that I'm obsessed with the big ships on the big lake, or anything. I'm just sayin'...
