An F-100 fighter jet pilot Jack Clapper flew sorties as part of the Misty FAC (forward air controller) program in the Vietnam War. Misty's primary mission was to fly F-100s at low altitudes and locate enemy targets along theHo Chi Minh trail in Laos. There were 155 pilots assigned to fly the Misty between June 1967 and May 1970. Of the 155 Mistys 34 were shot down.
