One person died after severe turbulence on a Singapore Airlines flight from London

“We can confirm that there are injuries and one fatality on board the Boeing 777-300ER,” the airline said in a statement. “We are working with local authorities in Thailand to provide necessary medical assistance and are sending a team to Bangkok to provide additional assistance if needed.”

The wide-body aircraft with 211 passengers and 18 crew on board was traveling from London Heathrow and was diverted to Suvarnabhumi Airport in Bangkok after encountering turbulence. Unconfirmed photos posted on social media showed food and other loose items scattered on the cabin floor. According to FlightRadar24, the plane took off from London at 10:38 p.m. local time on Monday.

Fatalities are extremely rare in turbulence, especially at cruising altitudes. The airline has not yet released any details about the accident. Airlines regularly advise passengers to keep their seatbelts fastened even if they are turned off, as unforeseen turbulence can occur.

The aircraft that operated flight SQ321 was 16 years old and is one of Singapore Air’s 23 777-300ERs. Boeing did not immediately comment on the incident.
