Terrorists attacked the United States. Two planes crashed into the World Trade Center towers in New York City. One plane crashed into the Pentagon in Arlington, Va. and another in a field in Shanksville, Penn. before reaching its intended target. Volunteer firefighters left their work and report to the fire station for staffing, not knowing what to expect next. Engine 52, staffed with career and volunteer firefighters, was transferred to the District of Columbia to protect the Nation’s Capital and filled in at DCFD Engine 15 while some volunteers staffed the remaining units in the station.
