Not what they meant by “burner” phone.

Passengers were forced to evacuate a Southwest Airlines plane after a phone battery caught fire while the plane was waiting to depart at Denver International Airport in Colorado.

“Everybody saw the smoke, because it kind of filled the back of the cabin,” said passenger Jennifer Rodgers, recalling the incident. It was reported by CBS News. “And then someone yelled ‘Fire’.”

The incident happened last Friday while Rodgers and 107 other passengers were on board SA Flight 3316, which was parked at the gate and waiting to fly to Houston, Texas.

According to eyewitnesses, a passenger’s smartphone started smoking, filling the cabin with acrid fumes and causing a chair to catch fire. It was reported by CNN.

Passengers were then ordered to evacuate with leaflets in the front exiting via the jet bridge while at the back of the aircraft they slid down the emergency chute to safety, as shown in dramatic video footage.

Meanwhile, crew members used a fire extinguisher to put out the flaming sky seat, Fox News reported.

Flight witness Jaquetta Anderson described the chaotic scene.

“There’s nowhere to go, because they exited through the back of the plane. And so I got a little bit pushed,” she says. “People were yelling leave your stuff. But I actually had two dogs with me, and I wasn’t going to leave them.”

Miraculously, only two passengers were injured during the mad dash: One passenger was reportedly injured during the evacuation while the passenger whose phone ignited the fire had to be treated for burns to his hand, the airline said in a statement.

The full flight landed three hours later at its destination at Houston’s William P. Hobby Airport, CNN reported.

Meanwhile, the incident is currently under investigation, according to the Federal Aviation Administration.

Unfortunately, batteries, especially lithium-ion batteries, have become a scourge in the friendly skies of late.

Last month, airline passengers in China were left fearing for their lives after a jet bridge at the airport was filled with smoke after a faulty power bank caught fire.

Such infernos usually occur when lithium-ion batteries overheat and catch fire.

In fact, due to the flammability of power banks, airlines only allow them to be packed in hand luggage, not in checked bags, for fear that they could start fires in the hold.
