PUBLIC HEALTH 

A commercial aviation euphemism for human waste treated with a blue liquid disinfectant, which freezes at high altitudes.

The solidified pee and poo may unintentionally leak out of an aircraft in midflight and plummet to the ground as golf ball- to beach ball-sized masses of yuck that can crash through roofs and nastify everything in their path. 27 incidents of blue ice impacts were recorded between 1979 and 2003; that was probably the tip of the iceberg. 

Synonyms Brown ice, yellow ice
