22-5-2024 (LONDON) A Singapore Airlines flight from London to Singapore has tragically underscored the grave risks posed by increasingly turbulent skies, a phenomenon exacerbated by the escalating effects of global climate change. The harrowing incident, which occurred over the Bay of Bengal on the afternoon of May 21st, 2024, claimed the life of one passenger while leaving scores more injured, some critically.
Flight SQ321, a Boeing 777-300ER carrying 211 passengers and 18 crew members, encountered severe and unexpected turbulence, prompting an emergency diversion to Bangkok’s Suvarnabhumi Airport. Accounts from those on board paint a terrifying picture of a sudden altitude drop that sent passengers and cabin items violently hurtling through the aircraft’s interior.
The chaos and fear of those harrowing moments culminated in the death of a 73-year-old British man, while over 30 others sustained injuries ranging from minor to critical. Multiple ambulances and emergency teams were immediately dispatched to the airport to triage and assist the injured upon the stricken aircraft’s landing.

Singapore Airlines has since extended its deepest condolences to the bereaved family and is fully cooperating with Thai authorities to support the injured passengers and investigate the incident’s causes.
However, this tragedy also serves as a sobering reminder of the broader challenges posed by climate change to aviation safety worldwide. Research indicates that rising global temperatures are profoundly disturbing atmospheric conditions, leading to more frequent and severe turbulence encounters.
Paul Williams, a professor of atmospheric science at the University of Reading, warns that clear air turbulence (CAT), which occurs without any visual warning signs, is becoming increasingly prevalent due to instability in the jet stream exacerbated by a warming atmosphere. His recent studies reveal a staggering surge of over 50% in incidents of severe clear air turbulence over the North Atlantic in just the past four decades, a trend expected to worsen as global warming continues unabated.
While reassuring that turbulence rarely causes injury to those properly restrained, Williams emphasizes the importance of passengers keeping their seat belts fastened during flights as a crucial precaution in our increasingly turbulent skies.
These findings are critical, as they highlight not just a rise in the insidious clear-air turbulence, which is undetectable by traditional radar systems, but an overall increase across all turbulence categories. The financial toll is also considerable, with the aviation industry in the United States alone incurring costs ranging from $150 million to $500 million annually due to turbulence-related incidents.
Clear-air turbulence, the culprit behind the recent SQ321 tragedy, poses a particularly formidable threat due to its ability to strike without warning. Caused by high-altitude air currents and unaccompanied by visible cloud formations, CAT is nearly impossible to detect using standard onboard weather radar systems.
While efforts are underway to develop advanced detection technologies such as LIDAR (Light Detection and Ranging) systems, which can sense turbulence up to 20 miles ahead, their current expense and bulk pose challenges to widespread adoption.
As turbulent flights potentially become more commonplace, the aviation industry must adapt through enhanced pilot training, improved aircraft design to withstand severe turbulence, and investment in cutting-edge detection technologies. Moreover, educating passengers on the importance of adhering to safety instructions, such as keeping seat belts fastened at all times, could significantly mitigate injuries during such incidents.
