Yes, Luftwaffe
Lieutenant Colonel Caesar von Hofacker was a member of the 20 July plot
and he paid the ultimate price for it. As did his fanatical, war criminal cousin,
General (RK-holder) Carl-Heinrich von Stülpnagel.
But also, there must have been resisters and British agents in the Luftwaffe high command/RLM who were morally and psychologically opposed to
AH and the Nazi ethos from the very beginning--they were everywhere else in the German war effort.
As to records,
"From the 1960s through the 1990s, the U.S. Government declassified the majority of its security-classified records relating to World War II. Yet, 60 years after the war, millions of pages of wartime and postwar records remained classified." https://www.cia.gov/readingroom/coll...disclosure-act
As for the British, we won't know the true story about Hess until 2040!!
