Several Injured as In-Flight Disturbance Strikes Delta Plane Arriving in Sydney, Australia

Multiple passengers and crew were hurt after a Delta jet traveling from LA to Sydney experienced turbulence this past Friday.

Flight DL41 "went through a short bout of rough air" as it made its approach and landed at the Sydney airport, a company official told. Several cabin crew members required medical attention.

The New South Wales Ambulance Service said they assessed a total of five people, and transported three to hospital with non-life-threatening injuries that included back pain and migraines. The injured ranged from their 30s to 70s.

It is the most recent case of commercial jets experiencing severe turbulence, with experts indicating that global warming is a major factor.

There were 245 passengers and a crew of 15 on the wide-body jet, the Delta spokesperson noted, stating that the plane arrived "safely and normally" at the airport at 06:48 local time on the day in question.

The NSW Ambulance Service indicated they were alerted just a mere three minutes before the plane landed, and emergency vehicles were standing by on the runway.

Why in-flight bumpiness is becoming increasingly prevalent - and more severe.

Last year, twenty-five passengers and crew were hurt when another Delta jet, on a route from Salt Lake City to Amsterdam, hit "significant" turbulence just 120 minutes into the long-haul flight, and had to make an unscheduled landing.

Recently, those on board on a certain international flight experienced a frightening short but intense period of extreme instability. A traveler died and many were hurt, as those without seatbelts were thrown from their seats and were slammed back.

Bumpy air is a common occurrence on aircraft journeys, and while instances of strong or severe turbulence seem to be rising, they are remained quite uncommon.

Estimates show that there are an estimated 5,000 incidents of significant in-flight disturbance each year, out of a sum of in excess of 35 million flights that now take off worldwide.

Intense turbulence is defined as when the sudden jolts of a aircraft going through unstable air exert greater than a significant G-force on your body - a strong enough force to throw you from your seat if you were not fastened by a restraint.

As a changing climate alters the conditions in the sky, experts warn that flying could become bumpier: warming trends and shifting wind patterns in the jet stream level are likely to increase the frequency and intensity of significant turbulence.
