A Number of Affected as Rough Air Impacts A Delta Airlines Flight Landing at Sydney, Australia

A number of individuals were hurt after a Delta jet originating in LA to Sydney experienced turbulence Friday morning.

Delta Flight 41 "encountered brief turbulence" as it made its approach and landed at the Sydney airport, a company official told. Several cabin crew members required medical attention.

Emergency medical services reported they evaluated a total of five people, and transported three to hospital with non-life-threatening injuries that comprised spinal discomfort and headaches. Those affected ranged from their thirties and seventies.

This marks the latest incident of commercial jets experiencing atmospheric disturbance, with researchers pointing out that climate change is a major factor.

There were 245 people and fifteen staff members on the wide-body jet, the representative added, stating that the plane touched down "safely" at Sydney Airport at shortly before 7 a.m. on Friday morning.

The NSW Ambulance Service indicated they got a call just three minutes ahead of the plane arrived, and response teams were ready and waiting at the airport.

Why in-flight bumpiness is becoming more frequent - and often stronger.

Last year, twenty-five passengers and crew sustained injuries when a separate Delta aircraft, on a route from Salt Lake City to Amsterdam, encountered "severe" atmospheric disturbance just 120 minutes into the lengthy trip, and diverted for an unscheduled landing.

Recently, those on board on a Singapore Airlines flight went through a harrowing five seconds bout of severe turbulence. An individual lost their life and dozens were injured, as unbelted passengers rose out of their seats and fell back down.

Turbulence is a common occurrence on aircraft journeys, and while occurrences of rough conditions seem to be rising, they are still very rare.

Data suggests that there are approximately 5,000 incidents of significant in-flight disturbance annually, out of a sum of over 35 million aircraft departures that currently occur worldwide.

Severe turbulence is described as when the vertical motions of a jet going through rough air masses apply greater than 1.5 times the force of gravity on your body - sufficient force to propel you from your seat if you weren't wearing a safety belt.

As climate change modifies atmospheric conditions, specialists caution that flying could become bumpier: warming trends and altered air currents in the jet stream level are expected to increase the occurrence and strength of dangerous in-flight bumps.
