On May 8, 2026, an individual scaled the perimeter fence at Denver International Airport, walked onto an active runway, and was struck by a departing aircraft. DIA's perimeter radar detected the threat three minutes before the fence was breached; the operator on duty attributed the alarm to wildlife visible in the same camera view. This analysis examines what the legacy architecture could not do, and what a modern perimeter architecture should do instead, for airports and for any critical infrastructure facility where a perimeter breach has consequences beyond the perimeter itself.
