ARLINGTON, Va. (AP) _ Twenty-five years after he disappeared in a plane crash in South Vietnam, Air Force Col. Carl Karst was buried at Arlington National Cemetery on Friday.

Vietnamese officials turned over Karst's remains in 1989, but they were not identified until last month by the U.S. Army's Central Identification Laboratory in Hawaii.

Karst was 38 when he was shot down while flying a Cessna O-1 ''Bird Dog'' reconnaissance plane on a routine mission Nov. 16, 1968.

A command pilot from Galatia, Kan., Karst had been in the Air Force 14 years and was awarded the Distinguished Flying Cross, Purple Heart, Bronze Star and Air Medal with Seven Oak Leaf Clusters.

Karst was buried with full honors and an Air Force flyover. He is survived by his wife, two sons and a daughter.
