Lake Peigneur
On November 20, 1980, a Texaco oil rig accidentally drilled into a salt mine under Lake Peigneur in Louisiana. The mistake caused a whirlpool to form in the lake, which sucked in the drilling platform, 11 barges, 65 acres of land, and countless trees. Shockingly, nobody died—the workers were able to escape thanks to a well-designed evacuation plan.
