Denver runway tragedy: Frontier A321 strikes crossing pedestrian during aborted takeoff

Video released by Denver airport shows a pedestrian crossing the runway as a Frontier Airlines Airbus A321 aborts takeoff for Los Angeles, striking and killing the person. The flight, carrying 224 passengers and seven crewmembers, aborted after the collision; cabin smoke prompted evacuation and 12 people suffered minor injuries, with five hospitalized. Authorities will release the victim’s identity and cause of death after notification of kin. The NTSB and FAA are investigating, and airport officials say they will review perimeter security as part of the ongoing inquiry.
