ABSTRACT
Continued Importance of Visual Identification 18. The multiplication of enemy decoy-fire sites hI the course of 1942 greatly added to the problell1s
of target location-as the Luftwaffe had found over llere. "GEE" was not sufficiently accurate to indicate whether a pronlising-Iookin.g fire was Olle started by our own aircraft at the aiming point (or, mistakenly, in the wrong place), or was an enemy decoy SOlne Iniles distant from the target. Only in clear weather conditions and with the assistance of moonlight could we have reasonable hopes of success. Even in the best possible c011ditions, however, illdustrial llaze generally prevented visual recognition of Ruhr targets.
