Authorities are investigating a breach at Mineta San Jose International Airport.
Police said 38-year-old Jerry Hyde somehow made his way onto the restricted airfield at SJC at 1 a.m. Thursday.
Airport officials said Hyde, a transient, made contact with an electrician, who was working on the airfield. The electrician then called airport police.
"We are reviewing what happened and what we can do to prevent it from happening again," SJC spokesperson Rosemary Barnes said.
The breach is at least the sixth time someone breached security at SJC in the last 18 months and comes after several enhancements to security at the airport, including higher fencing.
"In many areas, we increased it to 11 feet, far exceeding federal standards," Barnes said. "We even changed the mesh used on that fenceline, so it's very difficult to scale."
The improvements came after previous breaches at SJC.

In 2015, Deanna Predoehl was arrested and after allegedly hopping a fence at the airport. Also last year, Miguel Zaragoza was arrested on suspicion of jumping the fence, stealing a city maintenance truck and driving onto the property.
A report issued in 2015 signaled that Mineta San Jose had the fifth highest amount of breaches nationwide since 2004.
San Jose's most infamous breach came in 2014 when a teenager scaled an airport fence and stowed away in the wheel well of a commercial airplane en route to Hawaii, prompting national attention.
Still, many passengers on Thursday seemed undeterred by news of the breach.
"A little bit concerned, but I think security will take care of it," passenger Michael Tung said. "I think security at the airport has been pretty good."
Security upgrades at SJC will continue through next year, including hardware and software improvements.
