FILE - In this Sept. 8, 2008 file photo, planes taxi on runways at John F. Kennedy International Airport in New York. A man on a personal watercraft who became stranded in a bay easily breached Kennedy International Airport's security system, on Sunday, Aug. 12, 2012, by walking undetected across two runways and into a terminal. Daniel Casillo, 31, swam to a Jamaica Bay 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, manufactured by defense contractor Raytheon Co., is meant to safeguard against terrorists. (AP Photo/Mark Lennihan, File) less
