On an August morning in England in 1943, a group of American airmen were told that before the day was out they would deliver the blow that would win the war. Flying the legendary B-17 Flying Fortress, their mission was to destroy the industrial facilities that kept the Nazi war machine in business - Schweinfurt's ball-bearing factories. But a determined and ferocious defense awaited the bomber crews of the USAAF's Mighty 8 . Somehow, Navigator Elmer Bendiner and his crew survived, their faithful B-17, Tondelayo, carrying them home. Hundreds of their young compatriots did not. Vivid, powerful and often viscerally engaging, is a stunning testament to the skill, courage and sacrifice of the men who fought in WWII's deadliest campaign.
