Several Hurt as Rough Air Hits A Delta Airlines Aircraft into Sydney, Australia

Multiple passengers and crew have been injured following a Delta aircraft from Los Angeles to Sydney experienced rough air Friday morning.

Delta Flight 41 "experienced a brief period of turbulence" as it landed at Sydney Airport, an airline spokesperson told. Four flight attendants required medical attention.

Emergency medical services reported they evaluated five patients, and transported a trio to a medical facility with minor injuries that such as spinal discomfort and migraines. The injured were between their 30s up to the 70s.

It is the newest example of aircraft encountering atmospheric disturbance, with researchers pointing out that climate change is a key driver.

There were 245 people and fifteen staff members on the aircraft, the official noted, adding that the plane touched down "safely and normally" at the airport at 06:48 local time on the day in question.

Paramedics indicated they received a call just three minutes prior to the plane arrived, and emergency vehicles were standing by on the runway.

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

Last year, twenty-five passengers and crew sustained injuries when a Delta Airlines flight, flying from Salt Lake City to Amsterdam, encountered "considerable" rough air just two hours into the transoceanic journey, and had to make an emergency landing.

Earlier this year, travelers and staff on a certain international flight went through a terrifying five seconds bout of severe turbulence. A traveler passed away and dozens were injured, as unbelted passengers were thrown from their seats and fell back down.

Turbulence is fairly routine during flights, and while cases of rough conditions appear to be increasing, they are still very rare.

Research indicates that there are approximately five thousand cases of severe-or-greater turbulence annually, out of a sum of in excess of 35 million aircraft departures that currently occur around the world.

Intense turbulence is defined as when the sudden jolts of a plane experiencing disturbed air apply in excess of 1.5 times the force of gravity on your body - sufficient force to propel you from your seat if you were not fastened by a safety belt.

As climate change modifies atmospheric conditions, experts warn that air travel could become bumpier: shifts in temperature and altered air currents in the jet stream level are projected to heighten the occurrence and strength of dangerous in-flight bumps.
