Several Hurt as In-Flight Disturbance Impacts Delta Plane Landing at Sydney, Australia

Multiple passengers and crew were hurt following a Delta aircraft originating in Los Angeles to Sydney experienced turbulence this past Friday.

Delta Flight 41 "encountered brief turbulence" as it touched down at the Sydney airport, a representative for the carrier stated. Four flight attendants were injured.

Emergency medical services said they treated five individuals, and took three to hospital with non-life-threatening injuries that comprised spinal discomfort and headaches. Those affected ranged from their 30s to 70s.

It is the most recent case of commercial jets experiencing severe turbulence, with experts saying that climate change is a significant contributor.

On board were 245 passengers and a crew of 15 on the aircraft, the Delta spokesperson added, adding that the plane landed "safely and normally" at Sydney Airport at shortly before 7 a.m. on Friday.

The NSW Ambulance Service reported they were alerted just a mere three minutes ahead of the plane touched down, and emergency vehicles were waiting on the tarmac.

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

During the past year, 25 people were injured when a Delta Airlines flight, on a route from Salt Lake City to Amsterdam, Netherlands, experienced "considerable" turbulence just two hours into the lengthy trip, and diverted for an emergency landing.

Earlier this year, travelers and staff on a Singapore Airlines flight went through a harrowing five seconds period of extreme instability. One passenger passed away and dozens were injured, as unbelted passengers rose out of their seats and crashed back down.

Bumpy air is a common occurrence on aircraft journeys, and while cases of rough conditions seem to be rising, they are statistically infrequent.

Research indicates that there are approximately thousands of instances of severe-or-greater turbulence every year, out of a total of in excess of 35 million flights that are conducted worldwide.

Intense turbulence is described as when the up and down movements of a plane experiencing unstable air generate in excess of 1.5g-force on your body - a strong enough force to lift you out of your seat if you weren't wearing a restraint.

As a changing climate modifies atmospheric conditions, experts warn that flying could become more turbulent: warming trends and changing jet streams in the jet stream level are projected to boost the regularity and severity of dangerous in-flight bumps.
