Several Affected as In-Flight Disturbance Impacts A Delta Airlines Flight Landing at Sydney, Australia

Multiple passengers and crew were hurt when a Delta Airlines aircraft from LA to Sydney encountered rough air Friday morning.

Flight DL41 "encountered brief turbulence" as it touched down at Sydney Airport, a representative for the carrier stated. Four flight attendants required medical attention.

Emergency medical services said they evaluated five patients, and took three to the hospital with relatively minor issues that included pain in the back and headaches. Those affected spanned from their 30s up to the 70s.

It is the latest incident of aircraft experiencing severe turbulence, with experts saying that shifting climate patterns is a significant contributor.

There were 245 people and fifteen staff members on the wide-body jet, the Delta spokesperson said, stating that the plane arrived "safely and normally" at the airport at 6:48 a.m. local time on Friday.

Paramedics reported they were alerted just only 180 seconds ahead of the plane landed, and ambulances were standing by on the runway.

Why plane turbulence is growing increasingly prevalent - and often stronger.

In the previous year, two dozen individuals were hurt when another Delta jet, flying from Salt Lake City to Amsterdam, Netherlands, experienced "considerable" turbulence just two hours into the long-haul flight, and was forced to make an unscheduled landing.

Earlier this year, passengers and crew on a Singapore Airlines jet experienced a terrifying brief five-second of severe turbulence. One passenger passed away and numerous people sustained injuries, as unbelted passengers lifted out of their seats and were slammed back.

Turbulence is fairly routine while flying, and while cases of rough conditions are reportedly becoming more frequent, they are remained quite uncommon.

Estimates show that there are approximately thousands of instances of severe or worse turbulence annually, out of a total of in excess of 35 million flights that now take off around the world.

Intense turbulence is categorized as when the sudden jolts of a jet experiencing disturbed air generate in excess of 1.5g-force on your body - sufficient force to propel you from your seat if you were not fastened by a restraint.

As climate change shifts weather patterns, specialists caution that air travel could become more turbulent: warming trends and shifting wind patterns in the jet stream level are expected to increase the regularity and severity of severe turbulence.
