Multiple Affected as Rough Air Impacts A Delta Airlines Flight Arriving in Sydney, Australia

Multiple passengers and crew sustained injuries when a Delta Airlines aircraft from Los Angeles to Sydney encountered significant turbulence on Friday morning.

Flight DL41 "experienced a brief period of turbulence" as it landed at the Sydney airport, an airline spokesperson informed. Four flight attendants sustained injuries.

Emergency medical services said they treated five patients, and transferred a trio to the hospital with relatively minor issues that included back pain and headaches. The injured spanned from their 30s up to the 70s.

This marks the newest example of aircraft experiencing turbulence, with aviation specialists pointing out that shifting climate patterns is a major factor.

On board were nearly 250 travelers and fifteen staff members on the wide-body jet, the representative added, adding that the plane arrived "without further incident" at Sydney Airport at 6:48 a.m. local time on Friday.

The NSW Ambulance Service said they received a call just only 180 seconds prior to the plane touched down, and ambulances were waiting on the tarmac.

Why plane turbulence is getting more frequent - and potentially more dangerous.

During the past year, twenty-five passengers and crew were hurt when a separate Delta aircraft, flying from Salt Lake City, Utah to Amsterdam, hit "considerable" rough air just 120 minutes into the transoceanic journey, and had to make an precautionary landing.

Earlier this year, those on board on a certain international flight experienced a terrifying five seconds bout of severe turbulence. One passenger passed away and numerous people sustained injuries, as individuals not fastened in were thrown from their seats and fell back down.

In-flight turbulence is fairly routine while flying, and while occurrences of rough conditions appear to be increasing, they are statistically infrequent.

Estimates show that there are an estimated thousands of instances of severe or worse turbulence every year, out of a overall number of in excess of 35 million aircraft departures that now take off globally.

Strong atmospheric disturbance is described as when the vertical motions of a jet going through disturbed air generate more than 1.5g-force on your body - sufficient force to propel you from your seat if you were not fastened by a seatbelt.

As a changing climate modifies atmospheric conditions, experts warn that flying could become bumpier: shifts in temperature and altered air currents in the higher altitudes are likely to increase the frequency and intensity of dangerous in-flight bumps.
