Hello hanshauprich,
well the 'problem' is that in Centralne Archiwum Wojskowe (Polish Central Military Archive) in Rembertów there is a diary of one of the GAK 1 officers (probably cpt. Horst von Zitzewitz). It is not a KTB of GAK 1 but something like that.
Anyway to my surprise under 4.IX we have:
The reconnaissance group from now on can use only one plane.
And this mean that there were some planes under command of GAK 1!
Dear Robert please read your PM
