In the early 1950s, epic battles unfolded in the skies over North Korea as American and Russian fighters faced off in history's first jet war. This program explores the Korean War's aerial tactics, technology, and grim aftermath for downed pilots, many of whom disappeared without a trace. The Korean War pitted the two most advanced fighters of their day, the American F-86 Sabre and the Soviet MiG-15, in furious air battles in North Korea's notorious "MiG Alley." With the help of dramatic reconstructions, rare archival footage, and interviews with veteran American and Soviet pilots, NOVA puts viewers in the cockpit to experience the lethal split-second duels that erupted in MiG Alley.
