Authorities are questioning a 73-year-old driver who sped through a security gate at Miami International Airport and ended up on one of the main runways.
The man has not been identified. Police say he may have been disoriented when he drove passed security Friday morning.
He was quickly detained by police.
Airport spokesman Greg Chin said no flights or landings were delayed. Although the runway was closed for a short time, he said, the airport's other three runways were not affected.
