About 30 seconds after receiving clearance for departure, the pilot of Frontier Flight 4345 radioed the tower: “Tower, Frontier 4345, we’re stopping on the runway. We just hit somebody. We have an engine fire.”

The Airbus A321 was departing Denver for Los Angeles International Airport at about 11:19 p.m. and was carrying 224 passengers and seven crew members, airport officials said.

As controllers coordinated emergency crews, they asked the flight crew to confirm how many people were aboard. The pilot replied, “We have 231 souls on board … there was an individual walking across the runway.”

Moments later, the pilot warned that conditions inside the aircraft were worsening. 

“We’ve got smoke on the aircraft, we’re going to evacuate on the runway,” he said, according to the audio recording.

Passengers slid onto the runway and were later bused back to the terminal. Most continued to their destination on a replacement Frontier flight, airport officials said.

Denver airport authorities said the person struck breached security by jumping a perimeter fence and was hit within minutes while crossing the runway. Inspections found the fence line intact, officials said.

Twelve people reported minor injuries related to the evacuation, and five were taken to local hospitals for evaluation. No serious injuries among passengers or crew were reported.

In a statement, Frontier Airlines confirmed the aircraft struck a pedestrian during takeoff and said smoke in the cabin prompted the aborted departure and evacuation. The airline said it is cooperating with investigators and is “deeply saddened by this event.”

Transportation Secretary Sean Duffy described the person as a “trespasser” and emphasized that breaching airport security can have catastrophic consequences. 

“No one should EVER trespass on an airport,” Duffy said in a statement following the incident.

Runway 17L was closed for several hours as authorities investigated. The National Transportation Safety Board has been notified, and the Federal Aviation Administration and Transportation Security Administration are assisting in the investigation, officials said.

Behind the numbers

The plane carried 231 people total (224 passengers and 7 crew). Of those, 12 reported minor injuries and 5 were hospitalized. The plane was traveling approximately 146 mph at the time of impact. The pedestrian breached the fence just 2 minutes before being struck.

History lesson

Runway incursions and trespasser fatalities at airports, while rare, have occurred before. A comparable incident happened at Milan Bergamo Airport in July 2025, when a trespasser was sucked into an aircraft engine during taxi. Aviation security regulations require perimeter fencing and surveillance, but enforcement gaps have historically led to unauthorized airfield access at airports worldwide.

Solution spotlight

Emergency response crews from the Denver Fire Department extinguished the engine fire quickly, and all 231 people on board were evacuated via slides and bused to the terminal. Most passengers were rebooked on a new Frontier flight to Los Angeles by Saturday morning. The airport examined and confirmed the integrity of the perimeter fenceline as part of the immediate post-incident response.
