What Sank the Edmund Fitzgerald?

In November 1975, the Edmund Fitzgerald, the largest cargo ship on the Great Lakes, sailed alongside another ship, the Arthur M. Anderson, across the stormy Lake Superior in route to Detroit from Superior, Wisconsin. When a storm kicked up, the two ships, laden with iron ore, became separated. The Arthur M. Anderson, captained by Jesse Cooper, sought shelter in Whitefish Point where Captain Cooper contacted the Coast Guard about the Edmund Fitzgerald, whose captain, Ernest McSorely, had radioed that the ship was taking on water. At 7:10 p.m., the captain radioed the message “We are holding our own.” Five minutes later, the ship disappeared from radar and was never heard from again. The ship and all 29 sailors on board were lost to the icy waters of the northernmost Great Lake and were immortalized in the Gordon Lightfoot song, “The Wreck of the Edmund Fitzgerald.” While it is easy to chalk up the shipwreck to bad weather, the ship was built to handle the wind and waves and had been doing so for 15 years. Several theories have been presented to explain what could have finally sunk this formidable cargo vessel.
