dec 5, 1952 - London's Killer Fog

Description:

In the Great Smog of 1952, the city of London was brought to a standstill by a dense blanket of toxic smog that reduced visibility to a few feet. For five cold December days, a heavy fog combined with sulfurous fumes from coal fires, vehicle exhaust and power plants, blocking out the sun and creating a public health disaster. The "Big Smoke" was the worst air pollution crisis in European history, killing an estimated 8,000 to 12,000 people.
