Killer Fog

Killer Fog refers to episode 3 of the Season 2 of the television series Forensic Files which was broadcast for the first time on October 16, 1997.

Plot summary
One particular stretch on Interstate 75 in Tennessee seemed to be accident-prone resulting in seven multi-car accidents in 15 years including a 62-vehicle accident in 1978 and a 99-vehicle, multiple-fatality accident in 1990.

Each accident was caused by a sudden and impenetrable fog, which forced drivers to suddenly brake without concern for those behind them. Environmental experts and investigators analysed the elements of nature occurring during this unnaturally-thick fog and tried to determine possible water sources that could create so many vapors in the air.

They found one particular facility, the Bowater paper mill, near Calhoun and close to the interstate, that releases significant water vapors, which react to the weather and create this deadly fog. Bowater reached a $10 million settlement with victims and agreed to limit the use of pond 4.
