A Frontier Airlines flight aborted takeoff after hitting a pedestrian at Denver International Airport, prompting evacuations and a runway closure for investigation.
Denver International said that during the takeoff of Frontier Flight 4345, the aircraft reported striking a person at around 11:19 p.m. After the report, firefighters responded and tackled what the airport described as a brief engine fire at the scene.

Frontier did not provide further details. but said it was coordinating with the airport and other safety authorities as the incident was investigated.
Meanwhile, the flight’s operational details point to a large-scale disruption at a key hub. The Airbus A321, bound for Los Angeles, was carrying 224 passengers and seven crew members when the incident occurred, according to Frontier.
Twelve people reported minor injuries, Denver International said. Of those, five were transported to hospital. The airport’s updates also indicated that firefighters dealt with the engine fire briefly during the response.
At the time of the incident, an audio recording shared by ATC.com captured a pilot saying that the aircraft was stopping on the runway after hitting someone and that there was an engine fire. The clip reflects the abrupt shift from takeoff to immediate safety procedures.

Denver airport operations. and local law enforcement to gather additional information.. The agency’s involvement signals that the case will be examined under standard aviation incident review procedures.
