The pics are really great, the one mentioned above shows how "precise" the Allied bombing could be... but there are other pics revealing devstating effects...
Concerning Kassel:
There is something strange. Kassel-Rothwesten has some barracks even today ("Fritz-Erler-Kaserne"), which clearly show the shape of a (former) airfield:

But this looks very different.
Maybe a confusion by the Recce-pilot, maybe a falsified airfield, ... ?
