A view of the damaged west wall of the Pentagon Building in Washington, D. C. under reconstruction. The Building was damaged on 09/11/2001 when five members of the Al-Qaida terrorist group hijacked American airlines flight 77, a Boeing 757-200 commercial jetliner and crashed the aircraft into the Pentagon Building, killing themselves and all 64 passenger on board

The hijacked airliner that slammed into the Pentagon September 11th caused massive damage to the building and killed 125 people, in addition to the 64 onboard the aircraft. Massive recovery efforts are underway by a variety of governmental agencies that included the 3rd US Army Infantry (the Old Guard) from Fort Myer, Virginia, the Military District of Washington Engineer Company, and the US Army Criminal Investigation Command, Fort Belvoir, Virginia. The Pentagon was the third target of Al-Qaida, a group of fundamentalist Muslims. The others were, the twin towers of the World Trade Center (WTC) and one unknown, when the passengers brought that aircraft down in a Pennsylvania field

An aerial view, two days later, of the impact point on the Pentagon where the hijacked American Airlines Flight 77, a Boeing 757-200 entered, breaking up in the process. Shortly after 8 AM on September 11, 2001 in an attempt to frighten the American people, five members of Al-Qaida, a group of fundamentalist Islamic Muslims, hijacked Flight 77 from Dulles International Airport just outside Washington DC. About 9:30 AM they flew the aircraft and 64 passengers into the side of the Pentagon. The impact destroyed or damaged four of the five «rings,» in that section, that circle the building. That section of the Pentagon was in the finishing stages of a renovation program to re-enforce and update the building. Fire fighters fought the fire throughout the night. The Pentagon attack followed a similar attack, two hijacked passenger planes flown into the twin towers of the New York World Trade Center, on the same day, in what is being called the worst terrorist attack in history. The huge American flag visible to the right of the damaged area is a garrison flag sent from the US Army Band at nearby Fort Myer, Virginia. It is the largest authorized (20 x 38) flag for the military. 3rd Infantry soldiers and fire fighters unfurled the flag over the side. Each night floodlights illuminated it. Search and rescue operations continue looking for survivors and casualties
