Fly over Nazi Germany with BALL TURRET GUNNERS, perilously suspended beneath the fuselage of B-17 bombers, exposed to the fire of enemy fighters. In war, certain missions demand the most and constitute much of the legends of bravery. Journey back to the Second World War when fearless airmen manned the B-17's belly guns--glass bubbles that at any moment could become their coffin. The ball turret gunners called their work "flying the ball", others called it crazy!
