A man faces DUI and reckless endangerment charges and will undergo psychiatric tests after he sped his sport-utility vehicle through a fence Thursday and drove up and down two runways at Philadelphia International Airport, police said. Chief Inspector Joe Sullivan, who heads the Philadelphia Police Department's homeland security and counterterrorism division, said there was no connection to terrorism and that the 1999 Jeep Cherokee came up negative when K-9 units checked it for explosives or other types of hazardous materials.
