@foxnews: Newly released video shows the moment a person runs onto the runway at Denver International Airport and is fatally struck by a Frontier Airlines plane during takeoff. An airport spokesperson says the individual jumped a perimeter fence and entered the airfield two minutes later before the incident occurred. The person has not been identified and is not believed to be an airport employee. The incident triggered an engine fire, injuring 12 passengers, and sending five people to the hospital.
