Bangkok: One person has died aboard a London-Singapore flight that encountered severe turbulence, Singapore Airlines said Tuesday. The plane was diverted to Bangkok, where emergency crews rushed to help injured passengers amid stormy weather.
The Boeing 777-300ER, with a total of 211 passengers and 18 crew members on board, landed in Bangkok at 3.45 pm, the airline said in a Facebook post.

Emergency crews from Samitivej Srinakarin Hospital, about 20 km away from Suvarnabhumi Airport, were on site to transfer injured passengers from Flight SQ321 from Heathrow 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. 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 and analysed by The Associated Press showed the Singapore Airlines flight cruising at an altitude of 37,000 feet. Just after 0800 GMT, the Boeing 777 suddenly and sharply pitched down to 31,000 feet 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.
