The minister, who visited the injured cabin crew members in hospital, said passengers described a terrifying spell of turbulence lasting around four to five minutes.

'Passengers faced injuries during those five minutes'

"Passengers recalled turbulence lasting for about four to five minutes. It was during that period that they faced the injuries and difficulties inside the aircraft," Naidu said.

He added that while all injured passengers have been discharged from hospital, some crew members remain under medical observation after suffering spinal and neck injuries.

"A couple of crew members have spinal injuries near the tailbone and neck. They remain under medical supervision and are being provided all necessary support as advised by doctors," he said.

All passengers discharged, four crew members still under treatment

Air India said all 13 passengers admitted to hospital following the incident have been discharged.

"As of 15.30 hrs on August 5, all 13 passengers who were admitted to hospital following the incident involving Air India flight AI2379 from Phuket to Delhi on August 4 have been discharged. Four crew members remain under medical care and continue to receive treatment," an Air India spokesperson said.

The airline added that its teams continue to assist the injured crew members and their families.

Crew praised for continuing duties despite injuries

The Airbus A320neo, operating flight AI2379 from Phuket to Delhi, was carrying 137 passengers and eight crew members when it encountered severe turbulence about an hour before landing in Delhi.

According to the minister, medical teams were deployed immediately after the aircraft landed. While first aid was administered at the airport, those requiring further treatment were shifted to Medanta and Fortis hospitals.

Naidu praised the cabin crew for remaining on duty despite their injuries.

"Even after suffering injuries during those five minutes, the crew continued performing their duties for nearly another hour until the aircraft landed safely. They showed remarkable courage," he said.

Flight recorders being analysed

The incident is now being investigated by the Directorate General of Civil Aviation (DGCA), which is examining the aircraft's cockpit voice recorder (CVR) and flight data recorder (FDR).

"The aircraft was moved to a separate hangar after landing. The flight data recorder and the cockpit voice recorder are now with the DGCA. The facts will be made public once the investigation is complete," Naidu said.
