SAN JOSE, Calif. (KGO) -- Mineta San Jose International Airport is beefing up security in light of the recent breaches.
The airport is raising the height of the perimeter fence from six feet to 10 feet.
The most infamous breach came when a 15-year-old hopped the fence last April, and stowed away in the wheel well of a plane on a flight to Hawaii.
Just three weeks ago, officials found a 20-year-old woman inside the fenceline.
Airport officials say they are midway through the monthlong project.
"Our fenceline in all areas of airfield meets federal standards, but in light of the recent security incidents here at our airport, we're electing to increase the height of our fenceline at all areas of the airport," said Rosemary Barnes, airport public information officer.
The airport hopes the higher fence and barbed wire will discourage people from trying to climb the fence.
