Singapore Airlines Flight SQ321 from London to Singapore encountered severe turbulence over the Indian Ocean, causing a rapid 6,000-foot drop.

A 73-year-old British man died, likely from a heart attack, and over 30 passengers were injured, with seven in critical condition.

The Boeing 777-300ER made an emergency landing in Bangkok for medical treatment for the injured passengers.

Concerns are growing about climate change increasing turbulence incidents, with experts predicting a significant rise in clear air turbulence over India by 2050-2080.

Clear air turbulence, caused by wind shear instabilities, poses a hazardous and invisible threat to aircraft.

Pilots are trained to handle such conditions, prioritizing safety over inflight service, and taking precautions like reducing cargo load and ensuring enough fuel for diversions.

Singapore Airlines provided condolences, medical aid, and dispatched a support team, while Thailand's Transport Minister announced plans for a replacement flight to Singapore.

Flight safety measures, passenger reassurance, and operational adjustments are essential in addressing such incidents in the aviation sector.
