A Number of Hurt as Rough Air Hits A Delta Airlines Flight Arriving in Sydney, Australia

Several people sustained injuries following a Delta Airlines flight from LA to Sydney experienced turbulence Friday morning.

Flight DL41 "experienced a brief period of turbulence" as it landed at Sydney Airport, a representative for the carrier informed. A number of the onboard staff sustained injuries.

Local paramedics said they assessed a total of five people, and transported three to a medical facility with non-life-threatening injuries that included pain in the back and head pain. Those affected were between their 30s to 70s.

This marks the latest incident of planes experiencing severe turbulence, with experts pointing out that climate change is a key driver.

On board were 245 passengers and 15 crew members on the wide-body jet, the official said, adding that the plane arrived "safely and normally" at Sydney Airport at shortly before 7 a.m. on Friday morning.

Paramedics indicated they received a call just only 180 seconds ahead of the plane touched down, and response teams were waiting on the tarmac.

Why in-flight bumpiness is getting increasingly prevalent - and potentially more dangerous.

During the past year, 25 people were hurt when a Delta Airlines flight, on a route from Salt Lake City to Amsterdam, hit "significant" atmospheric disturbance just 120 minutes into the transoceanic journey, and had to make an emergency landing.

Recently, travelers and staff on a certain international flight experienced a frightening five seconds period of extreme instability. A traveler lost their life and dozens were injured, as unbelted passengers lifted out of their seats and crashed back down.

Turbulence is fairly routine during flights, and while instances of significant turbulence appear to be increasing, they are statistically infrequent.

Data suggests that there are around 5,000 incidents of severe-or-greater turbulence annually, out of a overall number of over 35 million journeys that are conducted around the world.

Strong atmospheric disturbance is described as when the up and down movements of a plane passing through unstable air apply more than a significant G-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 shifts atmospheric conditions, experts warn that air travel could become less smooth: warming trends and altered air currents in the higher altitudes are expected to boost the occurrence and strength of significant turbulence.
