The story

The grooved, gray concrete wall rising from a few inches to a few feet seems to be solely for blocking the noise from the nearby highway, but like many parts of the new Pentagon memorial, there is more to the wall than meets the eye.

Seven years after the September 11 attack on the Pentagon, the wall is designed to remind visitors of the youngest and oldest victims, wrapping the memorial in symbolic imagery.

It stands 3 inches tall at its beginning, representing the youngest person killed there -- 3-year-old Dana Falkenberg -- and continues to a height of 71 inches, corresponding to the oldest victim, retired U.S. Navy Capt. John D. Yamnicky Sr.

Both were aboard American Airlines Flight 77 when terrorists hijacked the plane and smashed it into the Pentagon that day. Falkenberg died with her mother and father, Charles Falkenberg and Leslie Whittington, and her 8-year-old sister, Zoe.

President Bush attended a solemn ceremony on the grounds Thursday, along with dignitaries and family members of those killed in the attack. See images of 9/11 Read full article »
