Help! Living Luftwaffe personal ground or air /Eastern front

Hi,
I am working on a film documentary about the end of war 1945/2015.
There my main story are the woman fighting squad of the soviet army (588 night bombing unit)

Where I have extreme problems is to find living Luftwaffe personal ( not only pilots, could be flak or mainent or other) that had experience with them.

This would inculde JAGDGESCHWADER Units like
77,3,51,52,54 and others.

Kurland Kessel
- Kaukasus ( Operation Blau) , hier vor allem die Regien MOZDOK,
Terek River Brückenkopf (1942)
fight of 1.Panzerarmee Ewald von Kleist ( on ground)
- Assinovskaya
- Kuban steppe
- „Black Sea, Novorossiysk and the Zone on the Sea of Azov, Temryuk.“

( Here was Willi Batz involved)


1944/45 ( all poland)

- Danzig
- Koesslin
- Schwerin
- Swinemuende


So it would be extremlyx important if anyone can help me finding a living witness. Further more film material of this would be also interesting.

I am going to speak to two russian nightfighters so thats gona be interesting )

Thanks, from Berlin Germany
