In response to regle's wise prompting to ask our questions whilst they may still be answered, I have a couple -
As a young lad after the war it was quite a thrill for me to have a "ride" in a Fraser-Nash type rear turret (powered but unarmed), but as I recall the response to the 'joystick' control lever was such that, ever since, I have thought it amazing that anyone could successfully engage an attacking aircraft with these. Quite clearly they did from time to time; I know I am asking a lot, but can anyone offer a first hand view as to how crews felt about the effectiveness of the powered turrets, and was there any opinion as to the value of the directly-aimed 0.5s as carried by the B17s?
