The following report, obtained from a German prisoner of war, describes
certain German aerial tactics used to lessen the effect of antiaircraft fire.
German fighter pilots have consistently used two forms of passive defense
against antiaircraft fire. They either continued flying at the same speed,
turning and twisting the aircraft in flight, or they throttled down the engine with
a view to giving the ground defenses the feeling that the airplane was at a lower
altitude than it really was, with the result that most of the fire was short.
