In an embarrassing incident for New York's John F. Kennedy airport, a lost jet-skier managed to walk undetected by security across airport property and runways. He now faces criminal trespass charges.

A jet-skier who became stranded in Jamaica Bay easily breached the security system at John F. Kennedy International Airport by walking undetected through two runways and into a terminal.

Daniel Castillo of Queens swam to shore and then walked past motion sensors and closed-circuit cameras of the airport's state-of-the art Perimeter Intrusion Detection System.

The $100 million system is meant to safeguard against terrorists.

Castillo climbed an eight-foot-tall perimeter fence and made his way to Terminal 3, according to The New York Post. He approached a Delta Air Lines worker, who alerted authorities, the paper said.

The Port Authority of New York and New Jersey is investigating. The agency says it has increased patrols on the ground and in the water and plans to meet with the security system's maker this week.

"We have called for an expedited review of the incident and a complete investigation to determine how Raytheon's perimeter intrusion detection system -- which exceeds federal requirements -- could be improved," the Port Authority said in a statement. "Our goal is to keep the region's airports safe and secure at all times."

Castillo was charged with criminal trespass. Information on whether he had an attorney wasn't available.
