Several Affected as Rough Air Impacts Delta Flight Arriving in Sydney, Australia

Multiple passengers and crew sustained injuries when a Delta jet from Los Angeles to Sydney, Australia was hit by rough air on Friday morning.

Flight DL41 "experienced a brief period of turbulence" as it touched down at Sydney Airport, a representative for the carrier told. Four flight attendants were injured.

Local paramedics said they evaluated five individuals, and transferred three to hospital with minor injuries that comprised pain in the back and head pain. The injured were between their thirties and seventies.

The event represents the newest example of commercial jets experiencing severe turbulence, with experts saying that global warming is a key driver.

The aircraft was carrying 245 people and 15 crew members on the Airbus A350, the Delta spokesperson noted, stating that the plane arrived "safely" at the airport at shortly before 7 a.m. on the day in question.

The NSW Ambulance Service said they were alerted just three minutes prior to the plane landed, and ambulances were standing by on the runway.

Why plane turbulence is growing more common - and often stronger.

Last year, twenty-five passengers and crew sustained injuries when another Delta jet, flying from Salt Lake City, Utah to Amsterdam, encountered "significant" atmospheric disturbance just two hours into the long-haul flight, and diverted for an emergency landing.

Recently, those on board on a Singapore Airlines jet experienced a frightening short but intense of severe turbulence. A traveler died and dozens were injured, as unbelted passengers rose out of their seats and crashed back down.

In-flight turbulence is a common occurrence while flying, and while occurrences of rough conditions are reportedly becoming more frequent, they are remained quite uncommon.

Data suggests that there are approximately 5,000 incidents of significant in-flight disturbance each year, out of a sum of over 35 million flights that now take off worldwide.

Severe turbulence is categorized as when the sudden jolts of a jet going through disturbed air exert more than a significant G-force on your body - sufficient force to lift you out of your seat if you were not fastened by a seatbelt.

As climate change modifies atmospheric conditions, specialists caution that air travel could become more turbulent: temperature changes and altered air currents in the higher altitudes are projected to increase the frequency and intensity of dangerous in-flight bumps.
