Trespasser Killed by Frontier Plane at Denver Airport; 17 Injured

According to a statement from Denver International Airport, the incident has also left 17 people injured, including five who were hospitalised.

The individual reportedly jumped the airport perimeter fence and ran onto the runway, where they were struck by Frontier Flight 4345 just two minutes later.

Emergency crews responded immediately, and passengers were bused to the terminal before departing on a replacement flight.

"Frontier Flight 4345 reported striking a pedestrian during takeoff at DEN. Emergency crews responded to the scene. Passengers were bussed to the terminal and the majority have since departed DEN on a new Frontier flight. DEN can confirm the pedestrian jumped the perimeter fence and was hit just two minutes later while crossing the runway," the statement read.

Airport authorities confirmed that the perimeter fence was intact, and preliminary findings indicate the trespasser was not an airport employee and has yet to be identified.

"The pedestrian is deceased, and is not believed to be an employee of the airport nor have they been identified. The airport has examined the fenceline and found it to be intact," the statement added.

The airport further added that Runway 17L remained closed temporarily for investigation.

"We are extremely saddened by this incident and express our sympathies to those involved," the statement added.

Following the incident, US Secretary of Transportation Sean Duffy condemned the breach, saying that the trespasser "deliberately scaled a perimeter fence and ran out onto a runway" during the takeoff.

In a post on X, Duffy stressed that airport security is the responsibility of local law enforcement and warned that "no one should ever trespass on an airport".

"A trespasser breached airport security at Denver Int'l Airport, deliberately scaled a perimeter fence, and ran out onto a runway. The trespasser on the runway was then struck by Frontier Airlines Flight 4345 during takeoff at high speed. The pilot stopped takeoff procedures immediately. The Frontier plane was then quickly evacuated while law enforcement and firefighters responded. Preliminary reports are 12 people were hurt, with 5 taken to the hospital," the post read.

He added that law enforcement agencies, along with the Federal Aviation Administration (FAA) and Transportation Security Administration (TSA), are investigating the incident.
