Rescue vehicles surround a U.S. military aircraft after it made an emergency landing at Benazir Bhutto International Airport in Islamabad September 17, 2010. The plane skidded off the runway during an emergency landing after a technical fault appeared in one of its engines, Pakistani aviation officials said. All passengers on board were safe although flight operations at the airport were suspended and several flights were diverted to other cities. REUTERS/Stringer (PAKISTAN - Tags: POLITICS TRANSPORT)
