A man dies on a plane

A plane traveling from London to Singapore experienced severe turbulance and was forced to an emergency landing at Bangkok Airport.

One passenger, a 73 -year-old British man, likely died from a heart attack. Additionally, 30 people were injured, including seven critically. The Boeing 777 hit an air pocket in Thai airspace, which led to turbulance. Many passengers and crew members were treated at a field hospital on the tarmac. One passenger recounted the terrifying moment when the turbulance hit. He described how objects flew through the air, and some passengers were injured. The seat belt sign had just turned on when the turbulence occurred. The man was uninjured because he had fastened his seatbelt in time.

Airline experts noted that sudden turbulence with no warning is rare but possible. The incident resulted in one death, seven critical injuries, and multiple other injuries among passengers and crew.
