Originally a World War II infantry training center, followed by a brief stint as a US Air Force base, Camp Wolters was redesignated a US Army installation in July 1956, and its primary mission was to train helicopter pilots. Mineral Wells offered an ideal climate and terrain for flight training with predominately clear skies, rolling open ranch land, high bluffs, and the Brazos River valley. An integral part of Mineral Wells' economy, the flight school expanded in the 1960s due to escalation of the Vietnam War. During the war, with the exception of the US Navy, all helicopter pilots receiving primary flight training passed through Fort Wolters. During its 17 years of operation, over 40,000 pilots were trained, which included international students from 33 countries. The last Fort Wolters pilots graduated in 1973, and it was formally closed in 1975 and was converted into an industrial center.  Wes J. Sheffield is an aviation/aerospace professional and historian.
