With a massive American flag flying overhead, members of the Dover Police and Fire Pipes and Drums play "Amazing Grace" during the dedication of a memorial to those killed Sept. 11, 2001, at the Air Mobility Command museum at Dover Air Force Base, Del. today. Shown closest to the camera is bagpiper Michael J. O'Connor, Jr., a Dover, Del., firefighter. The memorial, which incorporates two pieces of steel from World Trade Center tower one, a rock from the United Airlines Flight 93 crash site and a block from the damaged portion of the Pentagon, makes Delaware the 50th and final state to have a public memorial. The steel was acquired through the Port Authority of New York and New Jersey World Trade Center steel program. (U.S. Air Force photo/Greg L. Davis)
