Several people have been injured after a Delta Airlines flight from Los Angeles to Sydney was hit by turbulence on Friday morning. Delta Flight 41 'encountered brief turbulence' as it landed at Sydney Airport, an airline spokesperson told the BBC. Four flight attendants were injured. The New South Wales Ambulance Service said it assessed five patients, and took three to hospital with minor injuries that included back pain and headaches. The patients' ages ranged from their 30s to 70s. It is the latest incident of planes being hit by turbulence, with experts saying climate change is a major factor. There were 245 passengers and 15 crew members on the Airbus A350, the Delta spokesperson said, adding that the plane landed 'safely and normally' at Sydney Airport at 06:48 local time on Friday (19:48 GMT on Thursday). The NSW Ambulance Service said it received a call just three minutes before the plane landed, and emergency vehicles were waiting on the tarmac. Last year, 25 people were injured when a Delta Airlines flight, travelling from Salt Lake City to Amsterdam, hit 'significant' turbulence just two hours into the long-haul flight and had to make an emergency landing. In 2024, passengers and crew on a Singapore Airlines flight experienced a terrifying five seconds of severe turbulence, leading to one fatality and numerous injuries. Turbulence is not uncommon, and while cases of strong or severe turbulence seem to be rising, they remain rare, with around 5,000 incidents reported yearly among over 35 million flights globally. Severe turbulence, defined as exerting over 1.5g-force on the body, can lift unbelted individuals off their seats, raising alarms as climate change continues to alter atmospheric conditions, potentially increasing turbulence severity and frequency.
