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

Multiple passengers and crew sustained injuries after a Delta jet traveling from LA to Sydney, Australia experienced significant turbulence Friday morning.

Flight DL41 "encountered brief turbulence" as it made its approach and landed at the Sydney airport, an airline spokesperson told. Four flight attendants were injured.

Emergency medical services said they assessed a total of five people, and transferred a trio to the hospital with relatively minor issues that comprised spinal discomfort and headaches. The patients' ages spanned from their thirties and seventies.

The event represents the most recent case of aircraft encountering atmospheric disturbance, with researchers pointing out that global warming is a major factor.

There were 245 people and fifteen staff members on the Airbus A350, the representative added, stating that the plane landed "without further incident" at the airport at 6:48 a.m. local time on Friday morning.

Paramedics reported they were alerted just only 180 seconds ahead of the plane arrived, and emergency vehicles were ready and waiting at the airport.

The reasons turbulence is growing increasingly prevalent - and more severe.

Last year, 25 people sustained injuries when another Delta jet, on a route from Salt Lake City, Utah to Amsterdam, hit "considerable" atmospheric disturbance just 120 minutes into the lengthy trip, and had to make an precautionary landing.

Recently, those on board on a Singapore Airlines flight endured a frightening five seconds of severe turbulence. One passenger passed away and numerous people sustained injuries, as unbelted passengers lifted out of their seats and fell back down.

In-flight turbulence is fairly routine on aircraft journeys, and while cases of significant turbulence seem to be rising, they are statistically infrequent.

Data suggests that there are around thousands of instances of significant in-flight disturbance annually, out of a sum of over 35 million flights that currently occur around the world.

Intense turbulence is defined as when the up and down movements of a jet experiencing disturbed air exert greater than 1.5g-force on your body - a strong enough force to throw you from your seat if you were not fastened by a seatbelt.

As a changing climate modifies atmospheric conditions, researchers alert that air travel could become less smooth: temperature changes and shifting wind patterns in the jet stream level are expected to heighten the frequency and intensity of significant turbulence.
