(CNN) — A Frontier Airlines plane aborted takeoff after it struck a person on a runway at Denver International Airport late Friday, a spokesperson for the carrier and the Federal Aviation Administration told CNN.

Flight 4345, an Airbus A321, was departing from Denver en route to Los Angeles and carried 224 passengers and 7 crew members, Frontier Airlines said in a statement. It was scheduled to depart at 10:39 p.m. local time.

As the plane was departing, “the aircraft reportedly struck a pedestrian on the runway during takeoff,” the airline said. “Smoke was reported in the cabin and the pilots aborted takeoff. Passengers were then safely evacuated via slides as a matter of precaution.”

The Denver airport said the Frontier flight “reported striking a pedestrian” at approximately 11:19 p.m. local time. There was a brief engine fire that was quickly extinguished by the Denver Fire Department, the airport said in a statement early Saturday.

Passenger Jose Cervantes said he had just started feeling the plane tilt up when he heard a thud.

“I looked to my right, and I just see the right wing just on fire and like, it’s exploding,” Cervantes told CNN affiliate KCNC. “The aircraft lands back down, and they kind of like swivel side to side, and then they stop, shut it off right away, and then the cabin starts to fill up with smoke.”

“I thought I was going to burn to death. You know, when I just saw the fire and the smoke, I just thought I was going to burn,” Cervantes said.

Emergency crews responded to the scene and passengers were taken to the terminal, the airport added.

CNN has reached out to the Denver Fire Department and Denver Sheriff’s Department for more information.

Air traffic control audio, shared by the ATC.com app, captured the moment a pilot from the Frontier flight told controllers the plane “hit somebody.” Seconds later, a controller said emergency vehicles were being dispatched. “There was an individual walking across the runway,” the pilot can be heard saying.

The pilot told controllers there were 231 people and more than 21,000 pounds of fuel on board, according to the audio clip.

Data from flight-tracking website Flightradar24 showed the plane was accelerating at about 146 miles an hour at roughly 11:15 p.m. local time, before it aborted takeoff.

“We are deeply saddened by this event,” Frontier said.

The National Transportation Safety Board is coordinating with the FAA, Denver International Airport operations and local law enforcement to gather information about the incident, the NTSB said Saturday morning.

The FAA is investigating, spokesperson Jon Henning told CNN.

Runway 17L will remain closed while the investigation is conducted, the airport said.

This is a developing story and will be updated.
