World War II veteran Kenneth Payton, 93, and his son-in-law, David Gibson, both of Louisville view the exterior of a B-17 bomber on display at the Clark County Airport along U.S. 31 as part of The Liberty Foundation’s 2014 Salute to Veterans tour. The plane, which dates back to 1945, was used in the 1990 film "Memphis Belle", and is one of only 12 B-17 bombers in the world that are still able to fly. Staff photo by Christopher Fryer
