A Doha bound Indigo flight carrying 121 passengers on Saturday returned to the airport here, about 40 minutes after its departure due to technical issues, officials said.
As soon as the cargo smoke warning trigger was activated, the pilot got the nod of authorities to return and safely landed the aircraft at the airport here, they said.
In a statement, the airliner said, ".. flight which left for Doha returned to Chennai due to a cargo hold smoke warning which triggered inflight."
