Daniel Casillo, 31, whose jet ski failed in New York’s Jamaica Bay swam and walked into John F. Kennedy Airport, penetrating the airport’s $100 million, state-of-the-art security system. He was subsequently arrested for criminal trespassing.

Casillo got past the sophisticated system of motion sensors and closed-circuit cameras designed to safeguard against terrorists. Casillo’s night began innocently enough, as he and some friends were racing on jet skis in Jamaica Bay near JFK Airport when his watercraft stalled. After calling for and receiving no help, he managed to swim towards the only thing he could see, the runway lights at JFK.

He climbed an eight-foot barbed-wire perimeter fence and walked undetected through the airport’s perimeter intrusion detection system and across two runways into Delta’s terminal 3. He was dripping wet and wearing his bright yellow life jacket, before the security realised what had happened.
