According to a statement from Frontier Airlines, Flight 4345 had a total of 231 individuals on board at the time, comprising 224 passengers and seven crew members. The pilot reported that smoke had filled the cabin and an engine fire was detected, prompting an immediate decision to abort takeoff and evacuate the aircraft. Passengers exited the plane using emergency slides as a precautionary measure.

The airport confirmed that emergency services were quickly mobilised in response to the incident. The Denver Fire Department reported that they were able to extinguish the engine fire shortly after it was identified. Following the evacuation, passengers were transported back to the terminal by bus as safety protocols were enacted.
The airport’s statement indicated that the person struck by the aircraft did not seem to be affiliated with any operations on the runway. In light of the incident, airport security has begun inspecting the perimeter fencing to identify any breaches that may have allowed an individual to access the runway area.
Audio recordings from air traffic control captured the tense moments following the collision. The pilot can be heard reporting, “Tower, Frontier 4345, we’re stopping on the runway. Uh, we just hit somebody … we have an engine fire.” This alarming announcement highlighted the urgency of the situation and prompted swift action from emergency personnel on the ground.
Initial reports suggest that there was at least one minor injury sustained by a passenger during the evacuation, although further details about the incident remain unclear. Frontier Airlines expressed their concern, stating, “We are deeply saddened by this event,” and confirmed that an investigation is underway in collaboration with airport officials and relevant safety authorities.
The seriousness of the situation has drawn the attention of various oversight agencies. The National Transportation Safety Board (NTSB) has been notified and will be involved in the investigation to ascertain how the event transpired and to ensure similar incidents do not occur in the future.
As investigations continue, the section of the runway where the incident took place has been closed off to enable thorough examination and to secure the area. The Denver Police Department is also assisting with inquiries into the circumstances surrounding the pedestrian’s presence on the runway.
While the flight was officially destined for Los Angeles International Airport (LAX), the incident has raised important questions regarding airport safety protocols and the potential risks associated with runway access. Passengers and crew involved in the emergency evacuation should be commended for their calmness and commitment to safety during an extremely distressing situation.
Updates on the ongoing investigation are expected as authorities work to gather more information and determine the necessary steps to prevent such occurrences in the future. The situation highlights the critical importance of rigorous safety measures at airports, particularly regarding pedestrian access to operational runways.
