An Associated Press investigation shows that the security fences and gates at Philadelphia International Airport were breached 25 times from January 2004 through January 2015.
Few of the breaches were publicly reported, with one notable exception: In 2012, a man sped an SUV down a runway at 100 mph.
Philadelphia’s breaches ranked it second, behind San Francisco’s airport, in the analysis. Nationally, there were at least 268 breaches at 31 major U.S. airports.
Incidents included fence jumpers taking shortcuts, intoxicated drivers crashing through barriers and mentally ill intruders looking to hop flights. None was terrorism-related.
Airports say breaches are relatively rare. Security measures include fences, cameras and patrols, but there are gaps. Not all of the miles of fences are routinely patrolled or covered by video surveillance.
