A Frontier Airlines aircraft struck and killed a pedestrian on the runway at Denver International Airport, prompting an evacuation, according to reports from multiple outlets. NBC News reports that passengers and crew were evacuated safely after the incident, with the airline stating that all 224 passengers and seven crew members left the aircraft using evacuation slides. Other coverage describes a fire onboard following the collision and notes that the pedestrian on the runway died. The incident occurred during takeoff operations on Friday night, and eyewitness accounts from passengers, as described by NBC News, focus on the moments leading up to and during the evacuation. The sources agree on the core sequence: the plane collides with a person on the runway, the person is killed, and the aircraft is evacuated with slides. The reports do not provide further details in the supplied text about the pedestrian’s identity, the cause of the person being on the runway, or the aircraft’s immediate operational status beyond the reported onboard fire.
