People riding along a street on a smoggy day.

Following the smoggy atmosphere in China, Chinese authorities have urged pilot to master landing airplanes in a smoggy atmosphere..   

Authorities require captains of domestic flights into Beijing to master low-visibility landings to combat chronic flight delays that have been worsened by heavy smog  

Thick smog has canceled or delayed flights at the Beijing airport when the city's visibility goes down to a few hundred yards - though officials typically blame the delays on weather conditions rather than pollution.
