I have watched this program on the History Channel a couple of times in the past. If you haven't seen it before, it is well worth watching. Friday, July 7, 2006 - The History Channel ____________________________________________________ 6-7 pm (Central Time) -- Modern Marvels - Ball Turret Gunners. 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!
