in TNA AIR 14/2599, which is about the raid against Dusseldorf of 31.7./1.8.1942, an aiming point for each participating group is mentioned:

Group 1 - perch X
Group 4 - perch X
Group 5 - perch X
Group 91 - perch Z
Group 92 - perch X

In another document Y is also mentioned as an aiming point, in this case for groups 4 and 92.

After looking in many files, I have not been able to find a map or so, which shows the location of the aiming points.

Can anybody give me a hint where I can find this information?


Best wishes.
