On a "Best of Chris Fabry Live" broadcast, we're going back to April 1965. Decorated Air Force pilot Colonel Carlyle "Smitty" Harris was shot down over Vietnam. He had no idea what horrors awaited him in the infamous "Hanoi Hilton." By chance, he had learned a means of communication called the Tap Code. Hear his story and the importance of that secret code on a July 4 edition of Chris Fabry Live.
