Growing up, I was a WW2 history buff. I read everything I could find, and all of it was written to make it less ugly, less real. Once I commented to my Dad, a veteran. that the Germans had shot POW's at Malmedy. He firmly advised me that Germans were not alone in shooting prisoners. I was stunned. Not passing judgement at all, the SS had it coming in my mind. Still, not in any books at that time.
He never talked about the war. I knew he was part of the Eighth Army Air force, a belly gunner in a B-17. Sadly, it was years after he passed that the History channel ran a series titled "Suicide Missions" about WW2. One episode covered men in Europe in Sherman tanks, which only had a chance against German armor when they overwhelmed them in sheer numbers.
I still remember the episode on the B-17 belly gunners. Hydraulics were used to raise and lower the pod, they were not isolated or redundant. You couldn't escape from the pod once it was lowered, so even if the shot up plane made it back to base, you would not survive the landing. He never let on, never mentioned how many friends he lost. I just wish they had made that series before he passed away.
