That may be true, but a pilot can’t see through his own fuselage and wing no matter how high up on the aircraft the cockpit is. It really doesn’t take much angle of bank to start obscuring view.
Look at the location of the pilot’s eyes and then the leading edge of the wing. Then think about the length and width of a B-17. Now think about what the pilot would see as he gained altitude, prior to flying roughly level to the impact point. The B-17 would most certainly be visible from the cockpit of either a P-51 or a P-63.
yep... the whole concept of deflection shooting revolved around that.
