After landing in Denver, the cabin of American Airlines Flight 445 started to fill with smoke, prompting an emergency evacuation on the runway.
A hundred and fifty eight passengers and six crew were evacuated, according to American Airlines.
"There was smoke coming out of the wall," Captain Greg Pixley, a spokesman for the Denver Fire Department, told the Denver Post. "What caused it was contained to that one area. They are still investigating the cause."
While Pixley confirmed the smoke, he said there was no visible fire.

The airline confirmed the flight "was involved in an incident."
"While taxiing to the gate, the pilot was alerted to possible smoke in the cabin," American said in a statement. "The passengers and crew deplaned via the slides and are all in the terminal."
Mike Tsang, a passenger on the flight, took photos and video of the scene.
