More than 140 passengers and crew from a Singapore Airlines flight hit by heavy turbulence that left dozens injured and one dead finally reached Singapore on a relief flight on Wednesday morning after an emergency landing in Bangkok.
The London-Singapore flight on a Boeing 777-300ER plane diverted to Bangkok after the plane was buffeted by turbulence that flung passengers and crew around the cabin, slamming some into the ceiling.
A 73-year-old British passenger died of a suspected heart attack, according to an airport official, and Bangkok’s Samitivej Hospital said 20 passengers were in intensive care, nine had undergone surgery, while five more were awaiting surgery.
“There was a very dramatic drop so everyone seated and not wearing seatbelt was launched immediately into the ceiling, some people hit their heads on the baggage cabins overhead and dented it, they hit the places where lights and masks are and broke straight through it.”
Photographs of the interior of the plane showed gashes in the overhead cabin panels, oxygen masks and panels hanging from the ceiling and luggage strewn around.
A passenger said some people’s heads had slammed into the lights above the seats and broken the panels.
Singapore Airlines flew 131 passengers and 12 crew on the relief flight from Bangkok, which reached Singapore just before 5 a.m.
There were 211 passengers including many Australians, British and Singaporeans, and 18 crew on the original flight. Injured fliers and their families remained in Bangkok.
Bangkok Suvarnabhumi airport general manager Kittipong Kittikachorn said on Tuesday seven people were critically injured.
“On behalf of Singapore Airlines, I would like to express my deepest condolences to the family and loved ones of the deceased,” Singapore Airlines CEO Goh Choon Phong said in a video message.
Officers from Singapore’s Transport Safety Investigation Bureau arrived in Bangkok on Tuesday night, Singapore’s Transport Minister Chee Hong Tat said in a statement on Facebook.
As the incident involves a US company, Boeing, which makes the 777-300ER aircraft, the US National Transportation Safety Board (NTSB) was sending a representative and four technical advisers to support the investigation, he said.
The plane encountered sudden extreme turbulence, Goh said, and the pilot then declared a medical emergency and diverted to Bangkok.
Aircraft tracking provider FlightRadar 24 said the flight encountered “a rapid change in vertical rate, consistent with a sudden turbulence event” at 0749 GMT, based on flight tracking data.
“There were thunderstorms, some severe, in the area at the time,” it said.
Weather forecasting service AccuWeather said on Tuesday that rapidly developing, explosive thunderstorms near the flight path of Flight 321 most likely contributed to violent turbulence.
“Developing thunderstorms often have strong updrafts, a zone of upward moving air, that rises very rapidly, sometimes at more than 100 mph, and can leave pilots with little time to react if it occurs directly in front of the plane,” said Dan DePodwin, AccuWeather’s senior director of forecasting operations.
The sudden turbulence occurred over the Irrawaddy Basin in Myanmar, about 10 hours into the flight, Singapore Airlines said.
“It is not a rare occurrence for big thunderstorms in the Bay of Bengal. There are always the chances of bumps,” said an airline pilot who regularly flies to Singapore and Southeast Asia.
The pilot declined to be identified because he is not authorised to speak to the media.
“We were about 30 miles off track flying around the thunderstorms two days ago on the way to Singapore,” the pilot added.
