The Air Traffic Control systems, which help aircraft take off and land, crashed at the Delhi International Airport Thursday evening disrupting flights for more than an hour since 6.30 p.m.
“Flights have resumed,” an airport official said.
Earlier in the day, dense fog wrought havoc with flight schedules in the national capital.
“Fourteen domestic flights were delayed today (Thursday) because of the fog. However, the situation improved later in the day,” according to an official.
