Multiple Injured as In-Flight Disturbance Strikes A Delta Airlines Aircraft Arriving in Sydney, Australia

Several people have been injured when a Delta Airlines flight from Los Angeles to Sydney was hit by rough air Friday morning.

Flight DL41 "went through a short bout of rough air" as it landed at Sydney Airport, a company official told. Several cabin crew members sustained injuries.

The New South Wales Ambulance Service said they evaluated five patients, and transferred three to a medical facility with non-life-threatening injuries that comprised pain in the back and migraines. The injured spanned from their 30s to 70s.

It is the newest example of commercial jets experiencing turbulence, with aviation specialists pointing out that global warming is a significant contributor.

There were nearly 250 travelers and a crew of 15 on the wide-body jet, the representative noted, clarifying that the plane touched down "without further incident" at the airport at shortly before 7 a.m. on Friday morning.

Paramedics indicated they got a call just a mere three minutes ahead of the plane arrived, and emergency vehicles were standing by on the runway.

The reasons turbulence is becoming increasingly prevalent - and often stronger.

Last year, 25 people sustained injuries when a separate Delta aircraft, travelling from Salt Lake City to Amsterdam, experienced "significant" turbulence just 120 minutes into the long-haul flight, and diverted for an unscheduled landing.

Earlier this year, those on board on a Singapore Airlines flight endured a frightening short but intense bout of severe turbulence. A traveler lost their life and numerous people sustained injuries, as unbelted passengers were thrown from their seats and crashed back down.

Bumpy air is fairly routine while flying, and while cases of significant turbulence appear to be increasing, they are still very rare.

Estimates show that there are an estimated 5,000 incidents of significant in-flight disturbance annually, out of a overall number of over 35 million flights that currently occur around the world.

Intense turbulence is categorized as when the sudden jolts of a plane passing through rough air masses exert more than a significant G-force on your body - enough to throw you from your seat if you did not have on a restraint.

As global warming alters weather patterns, experts warn that flying could become bumpier: warming trends and changing jet streams in the upper atmosphere are expected to boost the occurrence and strength of significant turbulence.
