In March 2017, an Air India aircraft, carrying 15 passengers, travelling from Mumbai to Bhubaneswar made an emergency landing in Mumbai after smoke was detected in its cockpit. “A full emergency was declared at 2.30 pm for flight AI 669. The aircraft landed safe and emergency was withdrawn,” said an official from Mumbai airport.

He added that the local authority had declared an emergency initially but withdrawn it later. “The emergency has since been withdrawn, and passengers will depart from another aircraft at 4:15 PM,” he added.

IndiGo was yet again in news earlier in the day after a 65-year-old male passenger, identified as IB Tripathi, suffered a heart attack onboard the flight at Varanasi airport. The incident happened at around 10:20 AM. Tripathi was travelling alone, a report said.
