Photos: Pentagon 9/11 Memorial
The memorial features benches engraved with the names of each victim. The benches are aligned by year of birth. Names of the airline passengers who lost their lives are placed so visitors look away from the Pentagon toward the plane's path. Benches engraved with the names of the victims inside the Pentagon are placed so visitors face the south facade of the building where the plane hit.
Here are photos from today's visit.
