Goodbye sergeant, hello mister
MOUNTAIN HOME AIR FORCE BASE, Idaho -- Master Sgt. Yancy Mailes, 366th Fighter Wing historian, ensures equipment being used during an airshow here is properly secured in September 2005. Sergeant Mailes will retire from the Air Force after 20 years of service and return to the base as a civilian historian. Starting in 2003, the Air Force began converting its history program from military positions to a fully civilianized force. Sergeant Mailes will be one of the last enlisted historians to convert to a civilian position. (U.S. Air Force photo/Senior Airman Sergio Aguirre)
