Multiple Injured as Rough Air Strikes A Delta Airlines Plane Landing at Sydney, Australia

Several people sustained injuries after a Delta Airlines aircraft from Los Angeles to Sydney, Australia was hit by rough air Friday morning.

Delta Flight 41 "encountered brief turbulence" as it made its approach and landed at Sydney Airport, an airline spokesperson told. A number of the onboard staff required medical attention.

The New South Wales Ambulance Service reported they treated a total of five people, and transferred a trio to hospital with non-life-threatening injuries that such as back pain and head pain. The patients' ages ranged from their 30s to 70s.

The event represents the most recent case of planes encountering severe turbulence, with experts saying that shifting climate patterns is a major factor.

The aircraft was carrying 245 people and 15 crew members on the aircraft, the representative noted, adding that the plane touched down "without further incident" at the airport at 6:48 a.m. local time on Friday.

Emergency responders said they were alerted just only 180 seconds ahead of the plane arrived, and ambulances were ready and waiting at the airport.

Why in-flight bumpiness is growing more common - and more severe.

In the previous year, 25 people sustained injuries when a Delta Airlines flight, on a route from Salt Lake City, Utah to Amsterdam, experienced "considerable" turbulence just a couple of hours into the transoceanic journey, and diverted for an unscheduled landing.

Recently, those on board on a Singapore Airlines jet experienced a terrifying five seconds period of extreme instability. One passenger passed away and dozens were injured, as individuals not fastened in rose out of their seats and fell back down.

Bumpy air is not uncommon on aircraft journeys, and while instances of strong or severe turbulence seem to be rising, they are still very rare.

Estimates show that there are an estimated thousands of instances of significant in-flight disturbance annually, out of a sum of more than 35 million flights that now take off around the world.

Intense turbulence is described as when the sudden jolts of a plane passing through unstable air apply greater than a significant G-force on your body - enough to throw you from your seat if you did not have on a restraint.

As climate change alters atmospheric conditions, experts warn that air travel could become less smooth: temperature changes and shifting wind patterns in the jet stream level are projected to heighten the frequency and intensity of dangerous in-flight bumps.
