Denver runway – A Frontier Airlines flight struck and killed a pedestrian during takeoff at Denver International Airport. Air traffic control audio and evacuation details emerged.
A Frontier Airlines flight heading to Los Angeles turned deadly late Friday night at Denver International Airport, after it struck and killed a person on the runway during takeoff.
The incident happened just after 11 p.m.. local time, when the flight reported striking a pedestrian.. Air traffic control audio described the sudden escalation: a female controller warned colleagues that a person was seen walking on the runway. and shortly after. they learned that the person had been hit and killed by the aircraft.
According to the report, the audio included a chilling moment in which a controller said “limbs” and human remains could be seen on the ground. The exchange underscored how quickly the situation unfolded as the plane was already in the takeoff phase.
Frontier later stated that the Airbus A321 operating Frontier Flight 4345 had 224 passengers and 7 crew members onboard at the time of the incident. The same report says smoke was seen in the cabin after the pedestrian was struck, prompting safety action.
In response to what happened, passengers were evacuated. The airport then moved people by bus to the terminal, and the majority of passengers reportedly departed Denver on a new Frontier flight.
On Saturday morning, Denver International Airport released an official statement clarifying key points about the person involved. The airport said the individual “is not believed to be an employee of the airport,” and it has not yet been identified.
The statement also provided a timeline: at approximately 11:19 p.m., Frontier Flight 4345 reported striking a pedestrian during takeoff at DEN, and emergency crews responded. It went on to say the pedestrian jumped the perimeter fence and was hit just two minutes later while crossing the runway.
Denver International Airport added that the pedestrian is deceased, not believed to be an airport employee, and has not been identified. The airport also emphasized that it examined the fenceline and found it intact.
In the aftermath, the airport reported that 12 people suffered minor injuries, and five of those were transported to local hospitals. The airport concluded by expressing deep sadness and extending sympathies to everyone affected.
The runway has since been reopened, but the incident remains under investigation.. For travelers. the case highlights how rapidly emergencies can shift during departures—and why coordination between airport operations and air traffic control is critical when unexpected hazards appear on active runways.
As investigators review what led the pedestrian to enter the airfield and how the flight proceeded in the moments after the warning. the airport’s statement suggests the focus will include both the sequence of events and broader safety procedures.. While the airport reported its fence line was intact, the investigation will likely look closely at timing, detection, and response.
For the families and loved ones of the person who died. the tragedy is compounded by the public nature of the air traffic audio that captured the warning and immediate aftermath.. The report also reflects how multiple groups of people—passengers. crew. emergency responders. and controllers—were drawn into a single. frightening incident within minutes.
