A Number of Hurt as Rough Air Hits A Delta Airlines Plane into Sydney, Australia

Several people were hurt following a Delta jet from LA to Sydney, Australia encountered rough air on Friday morning.

The flight, numbered 41 "experienced a brief period of turbulence" as it touched down at Sydney Airport, an airline spokesperson told. Four flight attendants required medical attention.

Emergency medical services stated they evaluated a total of five people, and transported three of them to hospital with non-life-threatening injuries that comprised spinal discomfort and migraines. Those affected spanned from their 30s up to the 70s.

This marks the newest example of commercial jets encountering turbulence, with aviation specialists saying that global warming is a key driver.

The aircraft was carrying 245 people and 15 crew members on the Airbus A350, the Delta spokesperson said, adding that the plane arrived "safely" at the airport at 06:48 local time on Friday morning.

Emergency responders reported they received a call just a mere three minutes prior to the plane landed, and response teams were standing by on the runway.

The reasons turbulence is growing increasingly prevalent - and potentially more dangerous.

Last year, two dozen individuals were injured when a separate Delta aircraft, flying from Salt Lake City to Amsterdam, hit "significant" atmospheric disturbance just a couple of hours into the long-haul flight, and was forced to make an emergency landing.

Recently, passengers and crew on a Singapore Airlines jet endured a harrowing short but intense bout of severe turbulence. An individual died and dozens were injured, as individuals not fastened in were thrown from their seats and were slammed back.

Bumpy air is fairly routine while flying, and while cases of significant turbulence are reportedly becoming more frequent, they are remained quite uncommon.

Estimates show that there are approximately thousands of instances of significant in-flight disturbance annually, out of a total of more than 35 million journeys that currently occur around the world.

Severe turbulence is described as when the vertical motions of a plane experiencing rough air masses apply more than 1.5g-force on your body - enough to lift you out of your seat if you did not have on a safety belt.

As global warming shifts atmospheric conditions, researchers alert that commercial aviation could become bumpier: temperature changes and changing jet streams in the upper atmosphere are likely to increase the regularity and severity of significant turbulence.
