San Jose airport officials released video on Wednesday of a security breach at the airport that took place last month, the fourth in the past year.
The video, recorded late at night on January 29, is grainy but appears to show a man on the Tarmac.
Mineta San Jose International Airport has been trying to beef up security around its perimeter. Officers are patrolling more frequently, and SJC says that's how they caught the man in the video.
The airport is also asking for more funding from the FAA.
The most notable security breach at the airport happened last April. A teenager scaled the fence and hid in the wheel well of a plane heading to Hawaii. The 16-year old survived freezing temperatures during the five-hour flight. He was not charged.
