In a tragic incident, Singapore Airlines flight SQ 321 encountered "severe" turbulence while en route from London to Singapore, resulting in one passenger's death and multiple injuries. The Boeing 777-300ER, carrying 221 passengers and 18 crew members, departed from Heathrow Airport on Monday.

Approximately 90 minutes away from its destination, the flight was forced to divert to Bangkok, Thailand, due to the turbulence. Kittipong Kittikachorn, the general manager for Bangkok's Suvarnabhumi Airport, confirmed that six passengers were critically injured, while many others sustained minor to moderate injuries.

Eyewitness accounts paint a harrowing picture of the incident, with passengers describing how the aircraft suddenly tilted upwards and experienced violent shaking. Unrestrained individuals were launched into the ceiling, causing some to hit their heads on overhead baggage compartments, damaging them. The impact also caused damage to the compartments housing lights and masks.

Singapore Airlines expressed its condolences to the family of the deceased passenger and stated that its priority is to provide assistance to all those on board. The National Transportation Safety Board announced that it will be sending a team to aid in the investigation of the incident.

The majority of passengers on the flight, 56 in total, were from Australia. Additionally, 47 passengers were from the U.K. and four were Americans. Two American passengers were among those injured. The turbulence appears to have occurred in Thai airspace over the Andaman Sea.

Instead of arriving at Singapore Changi Airport as scheduled, the flight touched down in Thailand at approximately 3:45 p.m. local time. Boeing, the manufacturer of the aircraft, expressed its support for Singapore Airlines and extended condolences to the family of the deceased passenger.

As investigations continue into this tragic incident, Singapore Airlines and the relevant authorities are working together to determine the cause of the severe turbulence that led to the loss of one life and multiple injuries.
