Multiple Hurt as In-Flight Disturbance Impacts A Delta Airlines Plane Landing at Sydney, Australia

Multiple passengers and crew sustained injuries when a Delta Airlines jet originating in LA to Sydney, Australia was hit by turbulence this past Friday.

The flight, numbered 41 "experienced a brief period of turbulence" as it touched down at Sydney Airport, a company official told. Four flight attendants sustained injuries.

Emergency medical services said they assessed a total of five people, and transferred three of them to the hospital with relatively minor issues that such as spinal discomfort and migraines. The patients' ages were between their thirties and seventies.

This marks the latest incident of commercial jets being hit by turbulence, with aviation specialists pointing out that shifting climate patterns is a significant contributor.

The aircraft was carrying 245 passengers and 15 crew members on the aircraft, the representative said, stating that the plane arrived "safely and normally" at the airport at 6:48 a.m. local time on the day in question.

Paramedics reported they received a call just only 180 seconds ahead of the plane landed, and emergency vehicles were waiting on the tarmac.

Why plane turbulence is getting more common - and more severe.

Last year, two dozen individuals were hurt when another Delta jet, travelling from Salt Lake City, Utah to Amsterdam, encountered "significant" rough air just a couple of hours into the long-haul flight, and had to make an emergency landing.

Earlier this year, travelers and staff on a certain international flight endured a terrifying five seconds period of extreme instability. A traveler passed away and numerous people sustained injuries, as individuals not fastened in were thrown from their seats and crashed back down.

In-flight turbulence is not uncommon during flights, and while occurrences of significant turbulence seem to be rising, they are statistically infrequent.

Estimates show that there are an estimated five thousand cases of severe or worse turbulence every year, out of a sum of in excess of 35 million journeys that are conducted worldwide.

Severe turbulence is described as when the up and down movements of a plane going through unstable air generate greater than 1.5g-force on your body - sufficient force to throw you from your seat if you were not fastened by a safety belt.

As a changing climate alters weather patterns, experts warn that flying could become more turbulent: warming trends and altered air currents in the jet stream level are expected to heighten the regularity and severity of dangerous in-flight bumps.
