A horrific accident happened on Friday night, while a Frontier Airlines jet was attempting to take off, and I can only imagine how unpleasant this must’ve been for everyone involved. While I first covered this yesterday, I’d like to provide an update, as some more details have emerged about how exactly this incident happened.
“We just hit somebody,” says Frontier pilot
This incident took place late at night on Friday, May 8, 2026, and involves Frontier Airlines flight F94345, scheduled to operate from Denver (DEN) to Los Angeles (LAX). The flight was operated by a two-year-old Airbus A321neo with the registration code N646FR.
The aircraft pushed back from the gate and taxied out to runway 17L, where it began its takeoff roll at around 11:20PM. From there, we’ll let the air traffic control communication speak for itself:
Frontier pilot: “Tower, Frontier 4345, we’re stopping on the runway. We just hit somebody. We have an engine fire.”
Tower controller: “Frontier 4345, I see that. I’m gonna be rolling out the trucks now. Do you know the souls onboard and fuel remaining?
Frontier pilot: “All right, 4345, we have 231 souls onboard, we have 21,320 pounds of fuel onboard, there was an individual walking across the runway.”
Tower controller: “Okay, we are rolling the trucks now.”
Frontier pilot: “We’ve got smoke in the aircraft, we’re going to evacuate on the runway.”
According to flight tracking software, the plane reached a maximum speed of 127 knots (pretty close to its takeoff speed) before aborting its takeoff.
The airport initially confirmed the incident in a statement, writing the following:
“Frontier Flight 4345 reported striking a pedestrian during takeoff at DEN at approximately 11:19 p.m. on Friday, May 8 2026. There was a brief engine fire that was promptly extinguished by the Denver Fire Department. Emergency crews responded to the scene and bussed passengers to the terminal. 231 souls were on board. Emergency response and investigation are ongoing. The National Transportation Safety Board has been notified.”
How did the “pedestrian” get onto the Denver runway?
Understandably, the big question was how exactly a person managed to get onto the runway. It goes without saying that there are zero situations whereby you’d have a “pedestrian” just walking across an active runway at a major airport without air traffic control being aware, so one has to assume this was deliberate on some level.
That has now basically been confirmed. After reviewing airport footage, it was determined that the person had jumped the airport perimeter fence just two minutes before the accident. The fence was found to be intact, so this wasn’t a case of something being broken, but instead, this person managed to scale the fence. The airport doesn’t believe that this person was an employee of the airport, or otherwise had a connection to it.
We’ve also learned that following the accident and evacuation, 12 passengers had minor injuries, with five being transported to local hospitals. Seeing videos of an evacuation is always a bit dismaying. You have people taking their full size carry-on bags, and videoing everything (including the engine) as if they’re on an amusement park. I won’t even share the pictures or video of the engine here, since the whole thing is just grim.
Of course I feel horribly for the person who lost their life and their family, and may they rest in peace. I also can’t imagine how unpleasant this was for those onboard, and especially the pilots, as I don’t think there’s anything that can mentally prepare you for striking a person on a runway.
There are a lot of scenarios that pilots train for, but I imagine that striking a human with an aircraft is something that no one can be be prepared for. Listening to the air traffic control audio, you can just hear the complete shock in the pilot’s voice, and then also the panic in the air traffic controller’s voice.
Bottom line
A gruesome scene unfolded on Friday night at Denver Airport, where a Frontier Airlines Airbus A321neo reportedly struck a person during its takeoff roll, leading to an engine fire. The plane was evacuated on the runway, and several passengers suffered minor injuries due to that, but nothing major (and of course the person who was struck lost their life, sadly).
The initial investigation has shown that the person who was hit jumped an airport fence just two minutes before being struck, so I imagine that they sadly weren’t in a good mental place.
