Retired Col. Carlisle “Smitty” Harris, left, talks with retired Lt. Col. Richard “Gene” Smith Feb. 11 at the street named in honor of Colonel Harris's honor in 2007. Colonel Harris was a POW in Vietnam for nearly eight years and is credited for improvising the “Tap Code” while held in captivity. Colonel Smith was a POW in Vietnam for five and a half years and the wing ceremonial plaza is named in his honor. Feb 12 marked the 37th anniversary of Colonel Harris’ repatriation. Both former POW’s visited Columbus AFB to participate in the Major/Lieutenant Colonel promotion party at the Columbus Club. (U.S. Air Force photo/SrA Jacob Corbin)
