the way this artwork/Park is to be understood is. There is a name at the end of the bench, if you can read the name and you're facing the Pentagon the person lost their life in the Pentagon, if you can read the name and you're looking into clear blue sky away from the Pentagon they lost their life in the airplane. The benches simulate flight of the wing, running water underneath. They're lined up in the year the people were born. The name at the end of the bench represents the person at the bench is honoring, if there's names in the water underneath the bench those persons passed away as well but their bench is somewhere else in the park for these are family members.
