A Number of Injured as In-Flight Disturbance Strikes Delta Flight into Sydney, Australia

Multiple passengers and crew were hurt when a Delta Airlines flight from Los Angeles to Sydney experienced significant turbulence this past Friday.

The flight, numbered 41 "encountered brief turbulence" as it landed at the Sydney airport, a company official told. Four flight attendants required medical attention.

Emergency medical services said they treated a total of five people, and took a trio to the hospital with relatively minor issues that such as back pain and head pain. The patients' ages spanned from their 30s to 70s.

The event represents the latest incident of aircraft being hit by turbulence, with aviation specialists indicating that global warming is a significant contributor.

There were nearly 250 travelers and fifteen staff members on the aircraft, the official noted, clarifying that the plane arrived "safely and normally" at the airport at shortly before 7 a.m. on Friday morning.

The NSW Ambulance Service indicated they received a call just three minutes before the plane landed, and emergency vehicles were waiting on the tarmac.

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

During the past year, 25 people were hurt when a Delta Airlines flight, travelling from Salt Lake City, Utah to Amsterdam, Netherlands, hit "severe" turbulence just 120 minutes into the long-haul flight, and had to make an precautionary landing.

Recently, travelers and staff on a Singapore Airlines jet went through a frightening five seconds bout of severe turbulence. An individual lost their life and numerous people sustained injuries, as individuals not fastened in rose out of their seats and were slammed back.

In-flight turbulence is fairly routine on aircraft journeys, and while occurrences of rough conditions seem to be rising, they are remained quite uncommon.

Data suggests that there are an estimated 5,000 incidents of severe or worse turbulence each year, out of a total of in excess of 35 million journeys that now take off worldwide.

Severe turbulence is described as when the sudden jolts of a jet experiencing disturbed air apply more than a significant G-force on your body - enough to propel you from your seat if you did not have on a restraint.

As a changing climate alters the conditions in the sky, experts warn that flying could become more turbulent: temperature changes and shifting wind patterns in the jet stream level are likely to boost the occurrence and strength of dangerous in-flight bumps.
