Lake Peigneur: The Swirling Vortex of Doom: This is an amazing story of an engineering disaster.
Shortly after they abandoned the $5 million Texaco drilling platform, the crew watched in amazement as the huge platform and derrick overturned, and disappeared into a lake that was supposed to be shallow. Soon the water around that position began to turn. It was slow at first, but it steadily accelerated until it became a fast-moving whirlpool a quarter of a mile in diameter, with its center directly over the drill site.
Damn Interesting is pretty, well, damn interesting.
