Multiple Affected as Turbulence Impacts Delta Plane Landing at Sydney, Australia

Multiple passengers and crew sustained injuries after a Delta Airlines aircraft originating in Los Angeles to Sydney, Australia encountered significant turbulence on Friday morning.

Flight DL41 "encountered brief turbulence" as it landed at the Sydney airport, a company official informed. Several cabin crew members required medical attention.

The New South Wales Ambulance Service said they evaluated five patients, and transferred three of them to the hospital with non-life-threatening injuries that included spinal discomfort and migraines. Those affected were between their 30s to 70s.

This marks the most recent case of aircraft experiencing atmospheric disturbance, with researchers saying that global warming is a major factor.

The aircraft was carrying nearly 250 travelers and 15 crew members on the Airbus A350, the Delta spokesperson said, adding that the plane arrived "safely" at the airport at shortly before 7 a.m. on Friday.

Emergency responders indicated they were alerted just only 180 seconds ahead of the plane arrived, and emergency vehicles were waiting on the tarmac.

Why plane turbulence is getting more common - and often stronger.

During the past year, two dozen individuals sustained injuries when a separate Delta aircraft, flying from Salt Lake City to Amsterdam, encountered "significant" turbulence just a couple of hours into the transoceanic journey, and had to make an unscheduled landing.

Recently, those on board on a Singapore Airlines flight went through a frightening short but intense of severe turbulence. One passenger died and many were hurt, as individuals not fastened in were thrown from their seats and crashed back down.

Turbulence is fairly routine while flying, and while cases of significant turbulence appear to be increasing, they are remained quite uncommon.

Research indicates that there are an estimated five thousand cases of significant in-flight disturbance every year, out of a overall number of more than 35 million journeys that are conducted around the world.

Intense turbulence is defined as when the vertical motions of a aircraft experiencing unstable air generate greater than 1.5g-force on your body - enough to lift you out of your seat if you did not have on a restraint.

As global warming alters the conditions in the sky, specialists caution that flying could become bumpier: temperature changes and shifting wind patterns in the upper atmosphere are expected to increase the occurrence and strength of dangerous in-flight bumps.
