Severe turbulence on a Singapore Airlines flight from London to Singapore resulted in one death and multiple injuries.

Due to extreme turbulence caused by adverse weather, a Singapore Airlines flight from London to Singapore suffered multiple injuries and one fatality. In a Facebook post, Singapore Airlines stated that, at 3:45 p.m. local time, the aircraft SQ321, which was travelling from Heathrow Airport to Singapore, had to make an emergency landing at Suvarnabhumi Airport in Bangkok due to intense turbulence.

Singapore Airlines did not say how many passengers were hurt, despite rumours in the Thai media that there were thirty casualties.

“We can confirm that there are injuries and one fatality on board the Boeing 777-300ER. There were a total of 211 passengers and 18 crew on board,” the airline said.

Medical staff have boarded the aircraft to assess injuries, but the number of casualties has not been confirmed, according to Thai immigration police, and some unharmed passengers have been deplaned.

The deceased passenger’s name has not been made public.

“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,” Singapore Airlines added.

Emergency personnel from Samitivej Srinakarin Hospital were on hand to help injured passengers get medical attention as soon as they landed. A line of ambulances was seen flowing to the site in videos that Suvarnabhumi Airport shared on the messaging app LINE, according to The Associated Press.

The Singapore Airlines flight was travelling at a height of 37,000 feet, according to tracking data that was obtained by FlightRadar24 and examined by AP. The aircraft abruptly and violently dipped down to 31,000 feet over the course of around three minutes, shortly after 0800 GMT. After less than ten minutes at 31,000 feet, the plane descended quickly and touched down in Bangkok in less than thirty minutes.

This tragedy is Singapore Airlines’ first fatality since October 2000, when an aircraft crashed in Taiwan on takeoff, killing 83 people. As of right now, Singapore Airlines has had seven incidents, according to the Aviation Safety Network.
