An exciting two part program beginning with the heroic story of America's F-105 Thunderchiefs and the men who flew them over the hostile skys of North Vietnam. They flew their fighter-bombers down the Red River Valley, downtown into Hanoi, meeting intense Sam, flack, and MIGs waiting to pounce on them. Then watch as 6,000 U.S. Marines and South Vietnamese Rangers battle a North Vietnamese Army of 20,000 men trying to make Khe Sanh America's Dien Bien Phu. See U.S. aircraft drop nearly 100,000 tons of munitions down upon the North Vietnamese, while other planes fly in food, ammunition and medical supplies to the forces defending Khe Sanh. Terrific battle scenes as B-52's drop 59,542 tons of bombs, making it a battle the North Vietnamese regulars would never forget.
