The same thing, combined with daredevil pilots (or in this instance, navigator), enabled the Bismarck sinking. Basically the Bismarck AA guns either had problem tracking them, or the ammo didn't do much. And the torpedo that hit the Bismarck rudder was fired in part by the plane's navigator hanging over the side of the aircraft, and telling the pilot when to release to avoid the waves.
