Bangkok, Thailand—CNN A Singapore Airlines aircraft from London to Singapore was hit by strong turbulence, killing one and injuring 71.
The Boeing 777-300ER diverted to Bangkok, according to Singapore Airlines' Facebook page. It listed 211 passengers and 18 crew. The business first said that 30 passengers were hospitalized after the mid-air stoppage, while others received outpatient care at the airport.
The sole victim was 73-year-old British man Geoff Kitchen.
“Preliminary investigations indicate that the deceased suffered from a heart condition,” Bangkok's Suvarnabhumi International Airport General Manager Kittipong Kittikachorn said Tuesday, adding that the autopsy was proceeding.
The Thornbury Musical Theatre Group (TMTG), where Kitchen worked for almost 35 years, reported his death on Facebook, calling him “always a gentleman with the utmost honesty and integrity” who “always did what was right for the group.” 
CNN reported that the British Foreign Office was helping the family of a Singapore Airlines customer who died.
The airplane arrived in Bangkok around 3:45 p.m. local time (4:45 a.m. ET) Tuesday.
CNN said that Kittikachorn, who examined the plane, was alerted of the emergency landing 10 minutes before landing. He claimed many individuals had broken arms, but most suffered scrapes and bruises.
Kittikachorn said about 200 people were waiting to board aircraft, with several injured transported to Samitivej Srinakarin Hospital. A Singapore Airlines jet carrying 131 of the 211 passengers left Bangkok for Singapore, he added.
In an update, the hospital reported 71 injuries, including Malaysian, UK, New Zealand, Spanish, US, and Irish individuals. It stated six persons are critically hurt. Kittikachorn previously reported seven critical injuries.
FlightRadar24 reports that Singapore Airlines aircraft SQ321 experienced turbulence over Myanmar at 7:49 a.m. UTC (3:49 a.m. ET).
According to the airline, the jet “encountered sudden extreme turbulence over the Irrawaddy Basin [a river in Myanmar] at 37,000 feet, about 10 hours after departure.”
CNN Weather research suggests the airplane hit quickly developing thunderstorms over southern Myanmar on Tuesday during high turbulence.
