A Number of Affected as In-Flight Disturbance Impacts A Delta Airlines Flight Arriving in Sydney

The airline stated the aircraft encountered "short-lived instability" as it touched down at its destination.

Multiple passengers and crew sustained injuries when a Delta flight originating in Los Angeles to Sydney encountered significant turbulence Friday morning.

Delta Flight 41 "experienced a brief period of turbulence" as it made its approach and landed at Sydney Airport, a representative for the carrier told. Several cabin crew members sustained injuries.

The New South Wales Ambulance Service stated they treated a total of five people, and transported a trio to hospital with relatively minor issues that comprised spinal discomfort and headaches. The patients' ages were between their 30s to 70s.

It is the newest example of planes encountering atmospheric disturbance, with researchers indicating that climate change is a major factor.

The aircraft was carrying nearly 250 travelers and 15 crew members on the aircraft, the official said, adding that the plane landed "safely and normally" at the airport at 6:48 a.m. local time on the day in question.

Emergency responders said they received a call just a mere three minutes prior to the plane landed, and emergency vehicles were standing by on the runway.

Why in-flight bumpiness is becoming increasingly prevalent - and often stronger.

Last year, twenty-five passengers and crew sustained injuries when another Delta jet, flying from Salt Lake City, Utah to Amsterdam, experienced "significant" atmospheric disturbance just two hours into the long-haul flight, and diverted for an unscheduled landing.

Earlier this year, travelers and staff on a Singapore Airlines flight experienced a harrowing brief five-second bout of severe turbulence. A traveler died and numerous people sustained injuries, as unbelted passengers were thrown from their seats and crashed back down.

Bumpy air is not uncommon on aircraft journeys, and while occurrences of strong or severe turbulence are reportedly becoming more frequent, they are still very rare.

Research indicates that there are an estimated five thousand cases of severe-or-greater turbulence each year, out of a total of more than 35 million flights that are conducted worldwide.

Strong atmospheric disturbance is defined as when the up and down movements of a jet experiencing rough air masses generate greater 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 alters the conditions in the sky, experts warn that flying could become less smooth: temperature changes and altered air currents in the jet stream level are likely to increase the frequency and intensity of dangerous in-flight bumps.
