The coroner said suicide and it seems obvious to a person, but the guy was just busted for trespassing a month ago and the way he was walking didn’t look like suicidal intentions. He didn’t stop on the runway or look at the plane. I think it was just trespassing.

You realize the odds of ending up exactly in front of the jet engine by accident are basically zero.

You’re right. AI says only 1-3% chance:The Mathematical Hypothetical: The "Frogger" Scenario

If we remove security, ATC, and pilot awareness from the equation—imagine the pedestrian is invisible to everyone and blindly walks across the airfield—what are the raw statistical odds of getting hit?

They are surprisingly low, thanks to the sheer scale of the airport and the physics of airplanes.

1. The "Random Drop" Factor

DEN is the largest airport in North America by landmass, covering 53 square miles (about 34,000 acres). The vast majority of this land is empty prairie, solar farms, and support buildings. The actual concrete footprint of the six active runways makes up roughly 1% of the total property. If a pedestrian is randomly wandering the DEN property, the odds are overwhelmingly high that they will just be walking through dirt and tumbleweeds.

2. The Runway Crossing

Let's assume the pedestrian makes it to one of DEN's six active runways and decides to walk directly across it.

• The Distance: A standard runway at DEN is 150 feet wide.

• The Time: An average person walks at about 4.5 feet per second. It would take them roughly 33 seconds to cross the runway.

• The Traffic: DEN handles roughly 1,800 flight operations (takeoffs and landings) per day. Spread evenly across six runways, that is about 300 operations per runway, per day. During a busy hour, a single runway might see a plane every 3 to 5 minutes.

• The Window of Danger: Airplanes move fast. A commercial jet taking off or landing is traveling between 130 and 180 mph. Because they are moving so fast, the airplane only occupies a specific physical spot on the runway for a fraction of a second.

The Verdict

For the pedestrian to be hit, their 33-second crossing window has to perfectly intersect with the fraction of a second that a 150-mph airplane is occupying that exact slice of the runway.

Even if a pedestrian blindly walked across an active runway during peak rush hour, the mathematical probability of a direct collision is estimated to be in the low single digits (roughly a 1% to 3% chance per crossing). The vast majority of the time, the pedestrian would cross an empty stretch of concrete while planes take off a few minutes before or after they cross.

And that's not even taking into account that of the 150 foot wide runway, only the narrow strips occupied by the landing gear and the engines represent a potential collision zone. If the pedestrian is situated between the engines and the landing gear or between the engines and the edge of the runway, the plane would harmlessly pass above the pedestrian.

Without AI or engaging in advanced calculus I would peg the odds of an accidental collision at less than 0.1%.

If he did it on purpose, he had excellent timing. He didn't run to "catch" the plane. He also didn't stop on the runway to wait for the plane.

Well, the plane definitely caught him.

That's true, he made it look effortless. I guess we'll never know.

There is going to be a day where people get stuck on an aircraft and not make it out due to people trying to take their bags with them.

If you don’t want people to bring their bags then you need to fix this:

This kind of response creates a safety risk because now it’s “do I try to bring some stuff or do I lose my job (because I can’t get home without ID) or die because my meds can’t be replaced?”
