This is a series of dramatic films showing the rapidly maturing Army Air Force moving into high gear in the Fall of 1943. You'll see the B-17 "Berlin Sleeper" on one of her record breaking 102 missions. B-25 Mitchells battle North African mud to move out to their new base in occupied Italy. "Thunderbolts Over Europe" shows P-47s taking on the Luftwaffe on a dramatic bomber escort mission. Thirty-three Martin B-26 Marauder bombers, protected by RAF Spitfires, hit ship yards, power plants and workshops near Le Trait, France. You'll see the original newsreel footage of "The Memphis Belle's" last mission against the U Boat pens at Wilhelmshaven, Germany, with combat footage not shown in the later classic feature film of the same name.
