Soviet airmen's membership in the Communist Party?

[Franek Grabowski]

Franek, this sentence makes no sense ( I guess you get from Ryan's "Last battles"), Soviet government noticed soldiers family, party member or not, when they were killed, and their families received pension too.

Possibly, but I am certain that thousands of families were not notified. The issue was raised several times in Poland when enquires came to arrive, trying to solve fate of next of kin soldiers. Possibly it was due to chaos and another, party chain just ensured a family would be notified.

Franek, are you sure that he threarened him, because he was "zampolit"?
May be they failed to share a girl, may be some of them abused another etc. etc.... What were the reasons?

Sadly, no details in those documents. There was a very low discipline in the Soviet PPAF units, that is a fact. Another is, that almost every veteran of PPAF just hated politruks, as they called them.
