A terrifying and tragic event unfolded Friday night at Denver International Airport when a Frontier Airlines jet struck and killed a pedestrian on the runway, triggering an engine fire and a chaotic evacuation. The incident occurred just as the plane was preparing to depart for Los Angeles, and was captured in disturbing videos shared online.
The Collision and Its Aftermath
At approximately 11:19 p.m. local time (1:19 a.m. ET Saturday), Frontier Flight 4345, bound for Los Angeles International Airport, struck a pedestrian on the runway during takeoff. According to Denver International Airport, the collision resulted in an engine fire that was quickly extinguished.
The pedestrian, who had breached the airport’s perimeter fence just minutes before the incident, was pronounced dead at the scene. The individual, whose identity has not been publicly released, is not believed to have been an airport employee.
Passenger Reactions and Chaos on Board
As the plane accelerated down the runway, the loud crash and subsequent fire led to panic inside the cabin. Passengers captured the horrifying moment of impact in a video, which was later posted on social media.
In the video, a loud crashing sound can be heard, followed by screams from the passengers. The frightening ordeal was described by multiple passengers, many of whom shared their terror and confusion.
Nikil Thalanki, one of the passengers on board, described the moments immediately after the incident. “Smoke filled the cabin completely—it was super hard to breathe,” Thalanki told NBC affiliate KUSA. He recalled that passengers were instructed to remain seated for a few minutes before emergency exits were opened.
Fellow passenger Franco Valera recounted seeing the engine on fire and hearing a loud boom as the chaos unfolded. “I’m just trying to relax as everyone’s screaming, and people are getting up,” he said, describing the situation as “a little scary.”
Another passenger, Mohamed Hassan, said it was “the scariest experience” of his life. He remembered hearing a loud explosion and seeing the fire from his seat. Hassan described how emotions ran high and the passengers were stuck in the plane for a few minutes before being evacuated, during which he inhaled toxic fumes.
Evacuation and Minor Injuries
Once the emergency exits were opened, passengers rushed to evacuate the plane, leaving their belongings behind in the process. Kimberly Randel, a passenger on the flight, described the chaotic scene: “They made us leave our stuff, our bags, and we jumped.” Despite the panic, she and other passengers were safely evacuated.
Karen Moon, another passenger, expressed relief at being able to disembark safely. “Nothing happened to us other than a minor inconvenience. We’re alive, and that’s the good thing, right?” she said.
The Airbus A321, which was carrying 224 passengers and seven crew members, was evacuated via emergency slides after smoke filled the cabin. The Federal Aviation Administration (FAA) confirmed that it is investigating the incident.
In total, 12 people reported minor injuries, including five who were taken to local hospitals. The airport expressed its condolences for those involved, while emergency crews quickly responded to the scene, transporting passengers to the terminal.
Investigation and Airport Response
The incident prompted a full investigation by the FAA and the National Transportation Safety Board (NTSB), which has been notified. The airport confirmed that Runway 17L was shut down following the incident.
Transportation Secretary Sean Duffy expressed his concerns in a post on X (formerly Twitter), stating, “A trespasser breached airport security at Denver Int’l Airport, deliberately scaled a perimeter fence, and ran out onto a runway.” He emphasized the seriousness of airport trespassing, saying, “No one should EVER trespass on an airport.”
The airport authorities also commended the efforts of the pilots and the firefighter first responders who acted swiftly to prevent the fire from spreading. The Association of Flight Attendants-CWA praised the professionalism of the crew and responders, ensuring that everyone on board was safely evacuated.
A Disturbing Reminder of Airport Security
This incident serves as a disturbing reminder of the critical importance of airport security. The trespassing pedestrian’s actions led to a dangerous and frightening situation for passengers and crew members, as well as tragic consequences for the individual who breached the airport’s perimeter.
The swift response of the airline’s crew and first responders helped prevent further disaster, but the event has left a lasting impact on all involved.
