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

Several people were hurt after a Delta Airlines aircraft originating in LA to Sydney encountered significant turbulence Friday morning.

Flight DL41 "encountered brief turbulence" as it made its approach and landed at Sydney Airport, a company official told. Several cabin crew members were injured.

Emergency medical services stated they treated five patients, and transferred a trio to hospital with non-life-threatening injuries that comprised back pain and headaches. The patients' ages ranged from their 30s up to the 70s.

This marks the latest incident of commercial jets being hit by turbulence, with experts saying that shifting climate patterns is a major factor.

On board were 245 passengers and fifteen staff members on the wide-body jet, the Delta spokesperson said, stating that the plane landed "without further incident" at the airport at 6:48 a.m. local time on Friday.

Paramedics indicated they were alerted just a mere three minutes prior to the plane landed, and ambulances were standing by on the runway.

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

Last year, 25 people sustained injuries when another Delta jet, on a route from Salt Lake City, Utah to Amsterdam, encountered "severe" atmospheric disturbance just two hours into the lengthy trip, and had to make an precautionary landing.

Earlier this year, those on board on a certain international flight experienced a terrifying brief five-second of severe turbulence. One passenger died and numerous people sustained injuries, as unbelted passengers lifted out of their seats and were slammed back.

Bumpy air is a common occurrence while flying, and while cases of significant turbulence seem to be rising, they are statistically infrequent.

Research indicates that there are approximately 5,000 incidents of significant in-flight disturbance every year, out of a sum of more than 35 million journeys that currently occur worldwide.

Severe turbulence is defined as when the vertical motions of a plane experiencing rough air masses generate more than a significant G-force on your body - a strong enough force to propel you from your seat if you were not fastened by a restraint.

As global warming shifts weather patterns, specialists caution that air travel could become more turbulent: shifts in temperature and changing jet streams in the higher altitudes are likely to boost the frequency and intensity of dangerous in-flight bumps.
