Singapore Airlines says a person has died and others were injured when a London-Singapore flight encountered severe turbulence.
Singapore’s Flight SQ321 from Heathrow was diverted to Bangkok and landed at 3.45pm local time at Suvarnabhumi Airport, the airline announced on its Facebook page.
The airline said the aircraft was a Boeing 777-300ER with a total of 211 passengers and 18 crew on board.
It did not say at what point during the flight the death and injuries took place.
Emergency crews from Samitivej Srinakarin Hospital, about 20 kilometres away from Suvarnabhumi Airport, were on site to transfer injured passengers off the runway for treatment.
Videos posted on the LINE messaging platform by Suvarnabhumi Airport showed a line of ambulances streaming to the scene.
“Singapore Airlines offers its deepest condolences to the family of the deceased,” the airline said online.
“Our priority is to provide all possible assistance to all passengers and crew on board the aircraft.
“We are working with the local authorities in Thailand to provide the necessary medical assistance, and sending a team to Bangkok to provide any additional assistance needed.
Tracking data captured by FlightRadar24 showed the Singapore Airlines flight cruising at an altitude of 37,000 feet (11,300 metres).
Just after 8am (GMT), the Boeing 777 suddenly and sharply pitched down to 31,000ft (9,400m) over the span of some three minutes, the data shows.
The aircraft stayed at 31,000 feet for just under 10 minutes before rapidly descending and landing in Bangkok in just under half an hour.
The descent happened as the flight was over the Andaman Sea approaching Myanmar.
