A Number of Affected as In-Flight Disturbance Strikes A Delta Airlines Flight Landing at Sydney, Australia

Multiple passengers and crew were hurt when a Delta jet from LA to Sydney encountered turbulence Friday morning.

Flight DL41 "encountered brief turbulence" as it made its approach and landed at Sydney Airport, a company official told. Several cabin crew members required medical attention.

The New South Wales Ambulance Service said they treated five individuals, and transported a trio to a medical facility with non-life-threatening injuries that such as back pain and migraines. Those affected ranged from their thirties and seventies.

The event represents the newest example of planes experiencing turbulence, with researchers pointing out that shifting climate patterns is a key driver.

There were nearly 250 travelers and a crew of 15 on the wide-body jet, the official noted, clarifying that the plane touched down "safely" at Sydney Airport at 06:48 local time on Friday morning.

The NSW Ambulance Service indicated they were alerted just only 180 seconds ahead of the plane arrived, and ambulances were waiting on the tarmac.

The reasons turbulence is getting increasingly prevalent - and more severe.

In the previous year, 25 people sustained injuries when a separate Delta aircraft, on a route from Salt Lake City, Utah to Amsterdam, Netherlands, encountered "considerable" atmospheric disturbance just 120 minutes into the long-haul flight, and diverted for an precautionary landing.

Recently, travelers and staff on a certain international flight experienced a frightening five seconds of severe turbulence. An individual passed away and numerous people sustained injuries, as those without seatbelts were thrown from their seats and fell back down.

In-flight turbulence is a common occurrence on aircraft journeys, and while instances of strong or severe turbulence are reportedly becoming more frequent, they are remained quite uncommon.

Data suggests that there are approximately five thousand cases of severe or worse turbulence annually, out of a sum of in excess of 35 million aircraft departures that now take off globally.

Intense turbulence is categorized as when the vertical motions of a jet experiencing rough air masses generate greater than 1.5 times the force of gravity on your body - sufficient force to lift you out of your seat if you were not fastened by a safety belt.

As climate change shifts the conditions in the sky, experts warn that commercial aviation could become less smooth: shifts in temperature and shifting wind patterns in the upper atmosphere are expected to boost the regularity and severity of significant turbulence.
