Multiple Affected as Turbulence Strikes A Delta Airlines Flight Landing at Sydney

Several people were hurt following a Delta aircraft from LA to Sydney experienced rough air on Friday morning.

Flight DL41 "experienced a brief period of turbulence" as it touched down at the Sydney airport, an airline spokesperson informed. Four flight attendants were injured.

Emergency medical services said they treated a total of five people, and took a trio to a medical facility with non-life-threatening injuries that included spinal discomfort and headaches. The injured were between their 30s up to the 70s.

This marks the most recent case of commercial jets being hit by turbulence, with aviation specialists indicating that shifting climate patterns is a key driver.

The aircraft was carrying 245 people and fifteen staff members on the wide-body jet, the representative added, adding that the plane landed "safely and normally" at the airport at 6:48 a.m. local time on Friday.

The NSW Ambulance Service reported they were alerted just three minutes before the plane landed, and emergency vehicles were ready and waiting at the airport.

Why plane turbulence is getting increasingly prevalent - and often stronger.

Last year, two dozen individuals were injured when a Delta Airlines flight, travelling from Salt Lake City, Utah to Amsterdam, Netherlands, hit "significant" turbulence just two hours into the long-haul flight, and was forced to make an unscheduled landing.

Recently, passengers and crew on a certain international flight endured a terrifying five seconds period of extreme instability. An individual died and many were hurt, as those without seatbelts rose out of their seats and crashed back down.

In-flight turbulence is fairly routine on aircraft journeys, and while instances of significant turbulence appear to be increasing, they are statistically infrequent.

Research indicates that there are approximately 5,000 incidents of severe-or-greater turbulence annually, out of a total of over 35 million journeys that currently occur globally.

Intense turbulence is defined as when the up and down movements of a jet going through rough air masses generate greater than 1.5g-force on your body - a strong enough force to lift you out of your seat if you weren't wearing a seatbelt.

As climate change shifts atmospheric conditions, researchers alert that commercial aviation could become bumpier: warming trends and changing jet streams in the upper atmosphere are expected to boost the frequency and intensity of dangerous in-flight bumps.
