A 41-year-old man, Michael Mott, died after walking onto a Denver International Airport runway and being struck by a Frontier Airlines plane headed to Los Angeles.The collision caused the plane's engine to catch fire and led to an emergency evacuation, injuring twelve passengers.Authorities have ruled Mott's death a suicide, though no note was found.Surveillance footage showed Mott scaling an eight-foot barbed wire fence and crossing the runway within minutes.Despite triggering a security alarm, the airport operator initially misinterpreted the alert as wildlife activity.

Denver Airport CEO Phillip Washington emphasized that the airport’s 36-mile perimeter fence complies with FAA standards and multiple security measures are in place, including patrols, cameras, and radar systems.Police continue investigating Mott’s motivations, contacting family and acquaintances for insight.Mott had a long criminal history in Colorado, including arrests for violent felonies, domestic violence, and trespassing.The National Transportation Safety Board is reviewing the plane evacuation to determine if the injuries warrant further safety investigation.Officials acknowledge the difficulty of completely securing such a large airport against a determined individual.
