WASHINGTON (AFPN) –- Staff Sgt. Donald S. Carson’s name was added to the Vietnam Veteran's Memorial here May 13. Carson, a San Francisco native, was injured in a military aircraft accident in Thailand on April 12, 1963, and died a few days later. His name was omitted from the monument until now because of a clerical oversight. (U.S. Air Force photo by Tech. Sgt. Jim Varhegyi)
