No, not a b-movie title. A NASA photo of the aluminum oxide byproduct spill in western Hungary.

On Oct. 4, 2010, an accident occurred at the Ajkai Timföldgyar alumina (aluminum oxide) plant in western Hungary, when a corner wall of a waste-retaining pond broke, releasing a torrent of toxic red sludge down a local stream. Several nearby towns were inundated, including Kolontar and Devecser, where the sludge was up to 6.5 feet deep in places. Four people were killed immediately, several more were missing and dozens of residents were hospitalized for chemical burns.
