During the Vietnam War, a group of fighter pilots volunteered for what was largely seen as an impossible mission – preventing the delivery of weapons and supplies from the North into the South. These pilots were known by their radio call sign: Misty. Close to a dozen of them were from Colorado.
A new documentary, "The Misty Experiment: The Secret Battle for the Ho Chi Minh Trail," is airing on PBS. The executive producer is Dean Echenberg.
