KUALA LUMPUR, May 26 (Reuters) - The Singapore Airlines

(SIA) aircraft used for a flight in which a passenger

died during severe turbulence returned to Singapore on Sunday,

five days after its emergency landing in Bangkok, Channel News

Asia (CNA) reported.

A 73-year-old British man died of a suspected heart attack

and dozens were injured on Tuesday after flight SQ321, flying

from London to Singapore, encountered what the airline described

as sudden, extreme turbulence while flying over Myanmar.

The flight carrying 211 passengers and 18 crew diverted

to Bangkok for an emergency landing. At least 43 people who were

on board remain hospitalised in Bangkok, a hospital in the Thai

capital said on Saturday.

Flight tracking service Flightradar24 showed the aircraft,

operating as flight SQ9071, left Bangkok on Sunday at 0349 GMT

and arrived in Singapore at 0539 GMT.

"SIA obtained the necessary approvals from the relevant

authorities in Singapore and Thailand, the investigators, and

the aircraft manufacturer, and the aircraft was cleared by our

Engineering and Flight Operations teams, before departure,"

Singapore Airlines told CNA.
