Multiple Affected as Rough Air Strikes A Delta Airlines Aircraft into Sydney, Australia

A number of individuals sustained injuries after a Delta Airlines jet originating in LA to Sydney was hit by significant turbulence on Friday morning.

Flight DL41 "experienced a brief period of turbulence" as it made its approach and landed at Sydney Airport, a company official told. Four flight attendants were injured.

Local paramedics said they evaluated a total of five people, and transferred three to the hospital with non-life-threatening injuries that comprised spinal discomfort and head pain. The patients' ages were between their thirties and seventies.

This marks the latest incident of aircraft being hit by severe turbulence, with researchers pointing out that global warming is a major factor.

On board were 245 people and a crew of 15 on the wide-body jet, the representative added, adding that the plane landed "safely" at the airport at 6:48 a.m. local time on Friday.

The NSW Ambulance Service said they were alerted just a mere three minutes ahead of the plane arrived, and response teams were standing by on the runway.

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

In the previous year, two dozen individuals were hurt when a separate Delta aircraft, on a route from Salt Lake City to Amsterdam, Netherlands, experienced "severe" turbulence just 120 minutes into the lengthy trip, and was forced to make an emergency landing.

Recently, passengers and crew on a certain international flight experienced a frightening brief five-second of severe turbulence. An individual lost their life and numerous people sustained injuries, as individuals not fastened in rose out of their seats and crashed back down.

Bumpy air is a common occurrence while flying, and while instances of significant turbulence seem to be rising, they are still very rare.

Estimates show that there are an estimated thousands of instances of severe or worse turbulence each year, out of a sum of over 35 million aircraft departures that currently occur globally.

Intense turbulence is defined as when the vertical motions of a jet going through rough air masses generate more than a significant G-force on your body - enough to lift you out of your seat if you were not fastened by a restraint.

As global warming alters weather patterns, specialists caution that commercial aviation could become less smooth: warming trends and altered air currents in the jet stream level are expected to increase the occurrence and strength of dangerous in-flight bumps.
