Delhi's smog-fighting helicopters can't fly – because of smog

City administrators told they would be unable to help dissipate the smog until the smog itself cleared
An ambitious plan to use helicopters to fight Delhi's air pollution has been grounded because the aircraft cannot operate in the thick smog, underscoring growing frustration at authorities' inability to address the toxic haze engulfing the city.
Accusations that Narendra Modi's government is failing to take the crisis seriously were further fuelled on Tuesday when the environment minister, Harsh Vardhan, urged residents to remain calm, saying only "routine precautions" were needed, even though air quality levels remain "severe".
