A passenger has died after severe turbulence on a flight from London to Singapore

It’s the second fatal incident in the airline’s 77-year history, after a plane attempted to take off on the wrong runway in 2000. Singapore Airlines is often regarded as one of the world’s best carriers — one of just 10 to be ranked five stars by Skytrax.

Thailand’s 3PlusNews reported that 30 people were injured on the flight. The airline said there were 211 passengers and 18 crew on board. Images appeared to show several ambulances parked next to the plane on the tarmac at Bangkok Airport.

“Suddenly the aircraft starts tilting up and there was shaking, so I started bracing for what was happening, and very suddenly there was a very dramatic drop so everyone seated and not wearing seatbelt was launched immediately into the ceiling,” Dzafran Azmir, a 28-year-old student on board the flight told Reuters.

“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,” he added.

Sky News obtained pictures of the aftermath on board, showing damaged parts hanging from the ceiling, food strewn about the galley, and a bloodied passenger.

“Our priority is to provide all possible assistance to all passengers and crew on board the aircraft,” Singapore Airlines said in the statement.

Severe turbulence can often result in injuries with passengers hitting the cabin ceiling, but deaths are extremely rare.

Last month, an Air New Zealand passenger said he broke his leg due to turbulence and had to endure the rest of the six-and-a-half hour flight in pain. And in December, 14 people received medical attention after severe turbulence on an Emirates Airbus A380.
