Federal Aviation officials are investigating six cases of pilots who strayed into a no-fly zone set-up to protect the Super Bowl in Arlington.
All of the violations appeared to be accidental, and not attempts to disrupt the game, Lunsford said.
As the planes flew into the fringes of the zone set up around Cowboys Stadium, they were intercepted by helicopters enforcing the flight restrictions. No fighter jets were scrambled, and all of the aircraft involved appeared to be small private planes.
Air Traffic controllers were busy into the night on Super Bowl Sunday. The FAA saw more than 400 departures of private jets from the DFW area after the game, 191 from Dallas Love Field alone.
