Description: Jeremiah Denton was a naval aviator who was captured and became a POW for eight years in Viet Nam. In 1966 he was forced to take part in a propaganda video. During the filming he pretended to be bothered by the lights but was in fact blinking out the word torture in Morse code. This confirmed for the first time that captured servicemen were indeed being tortured. Mr. Denton went on to serve as a U.S. Senator from the state of Alabama. This secret message could be used as a starting point for a unit on waves and information. Students could create and send messages of their own, hopefully under much more enjoyable conditions.
