On Friday night, a Frontier Airlines Airbus A321 struck and killed a pedestrian on the runway at Denver International Airport as it was taking off for Los Angeles. The unidentified individual had jumped the airport's perimeter fence just minutes before the collision, which occurred approximately two minutes after breaching the fence. Following the impact, the aircraft aborted takeoff, and an engine fire was reported, prompting an emergency evacuation of the 224 passengers and seven crew members onboard. Emergency crews responded quickly, and passengers exited using emergency slides, with some being transported back to the terminal by bus. Reports indicate that twelve passengers suffered minor injuries, while five were hospitalized. The airport has closed the runway for investigation, with authorities examining how the pedestrian accessed the restricted area. This tragic event follows another incident at Orlando International Airport where a Delta Air Lines employee was killed, raising serious questions about airport security measures.
