On September 11, 2001, 19 Al-Qaeda members hijacked four passenger jets within the Northeastern United States in a series of coordinated terrorist attacks. Two planes crashed into the Twin Towers of the World Trade Center in New York City, the third into the Pentagon in Arlington County, Virginia, and the fourth inadvertently into a field near Shanksville, Pennsylvania. The attacks cost the lives of 2,996 people (including the 19 hijackers), caused the destruction of the Twin Towers, and damaged the western side of the Pentagon. Soon after 9/11, "The New York Times" released a story stating that the CIA's New York field office was destroyed in the wake of the attacks. According to unnamed CIA sources, while first responders, military personnel and volunteers were conducting rescue efforts at the World Trade Center site, a special CIA team was searching the rubble for both digital and paper copies of classified documents. This was done according to well-rehearsed document recovery procedures put in place after the Iranian takeover of the United States Embassy in Tehran in 1979. While it was not confirmed whether the agency was able to retrieve the classified information, it is known that all agents present that day fled the building safely.
