Last Monday, a college friend served as our tour guide of the Pentagon. I worked in the Pentagon from Jun4 1995 - July 1997 at the Single Agency Manager (SAM) for Information Technology Services (ITS). My office reworked the the infrastructure during the Pentagon renovation - a renovation that would lessen the impact of the plane crash on September 11, 2001. Above is the Pentagon from 1998 (Public Domain at this link).
The plane crashed into the section to the left of the forward parking lot (the white concrete was a helicopter pad). This section is now the Pentagon Memorial.
Across from the Pentagon is the Air Force Memorial. From its website (link),
The United States Air Force Memorial honors the service and sacrifices of the men and women of the United States Air Force and its predecessor organizations, including the Aeronautical Division, U.S. Signal Corps; the Aviation Section, U.S. Signal Corps; the Division of Military Aeronautics, Secretary of War; the Army Air Service; the U.S. Army Air Corps; and the U.S. Army Air Forces. More than 54,000 Airmen have died in combat while serving in the Air Force and these historical service arms of the military.
Above is the Washington Memorial. Below is the "missing man" etching.
