Multiple Affected as In-Flight Disturbance Impacts A Delta Airlines Flight into Sydney, Australia

Several people sustained injuries following a Delta flight traveling from Los Angeles to Sydney, Australia encountered rough air Friday morning.

Delta Flight 41 "experienced a brief period of turbulence" as it made its approach and landed at the Sydney airport, an airline spokesperson told. Four flight attendants sustained injuries.

Local paramedics said they evaluated a total of five people, and transported three of them to a medical facility with relatively minor issues that such as pain in the back and migraines. The patients' ages spanned from their 30s up to the 70s.

It is the most recent case of planes experiencing atmospheric disturbance, with experts saying that global warming is a key driver.

On board were nearly 250 travelers and fifteen staff members on the Airbus A350, the Delta spokesperson added, clarifying that the plane touched down "without further incident" at Sydney Airport at shortly before 7 a.m. on the day in question.

Paramedics said they were alerted just a mere three minutes prior to the plane touched down, and ambulances were ready and waiting at the airport.

Why plane turbulence is growing increasingly prevalent - and more severe.

In the previous year, 25 people were injured when a separate Delta aircraft, travelling from Salt Lake City to Amsterdam, Netherlands, hit "considerable" rough air just a couple of hours into the transoceanic journey, and was forced to make an emergency landing.

Recently, travelers and staff on a Singapore Airlines flight endured a frightening brief five-second period of extreme instability. One passenger died and dozens were injured, as individuals not fastened in rose out of their seats and were slammed back.

In-flight turbulence is not uncommon on aircraft journeys, and while cases of significant turbulence appear to be increasing, they are still very rare.

Research indicates that there are around thousands of instances of severe or worse turbulence every year, out of a total of in excess of 35 million journeys that are conducted worldwide.

Strong atmospheric disturbance is categorized as when the up and down movements of a jet passing through unstable air exert greater than a significant G-force on your body - sufficient force to lift you out of your seat if you weren't wearing a restraint.

As global warming shifts the conditions in the sky, specialists caution that air travel could become less smooth: shifts in temperature and altered air currents in the upper atmosphere are expected to boost the frequency and intensity of severe turbulence.
