"It is difficult for the modern (2008) UK resident to comprehend what World War II fogs were like. It was not uncommon for a person to be unable to see the hand at the end of an outstretched arm. The post-war Clean Air Act hugely ameliorated UK fogs" - - B. Main-Smith.

Never heard of such a thing. English pea-soup fog during wartime aviation [especially during hours of darkness] and impediment to landing combat warplanes a solution found.

This was FIDO. As extracted from the wiki entry.

"Fog Investigation and Dispersal Operation (FIDO) (which was sometimes referred to as 'Fog Intense Dispersal Operation' or 'Fog Intense Dispersal Of]") was a system used for dispersing fog from an airfield so that aircraft could land safely. The device was developed by Arthur Hartley for British RAF bomber stations, allowing the landing of aircraft returning from raids over Germany in poor visibility by burning fuel in rows on either side of the runway."

"The system".

"The device consisted of two pipelines situated along both sides of the runway and through which a fuel (usually the petrol from the airfield's own fuel dump) was pumped along and then out through burner jets positioned at intervals along the pipelines. The vapours were lit from a series of burners, producing walls of flame. The FIDO installation usually stored its fuel in four circular upright tanks built at the edge of the airfield with a low brick bund wall in case of leakage. The tanks were usually encased in ordinary brickwork as protection from bomb splinters or cannon fire."

Read further the English pea-soup fog as deemed a problem for English society in general. Remediation and elimination of the phenomenon finally accomplished in the last few decades.
