Amy,
the reasons against a working relation of Einstein in the aircraft production are doubtless overwhelming but I think I met a social need for conspiracy theories here! *
Let us assume there was a cheating braggart claiming (and convincing the enterprise Merkur and the Idflieg) that he was actually "Einstein". *8)
Cases of wrong knights of the Pour le mérite or other orders were known in WWI in Germany! *
The question is still open for speculations:
Who was "Prof. Dr. Einstein"? Any suggestion welcome!

PS: >>Referencing another thread, perhaps Einstein's dying and prophetic words to his nurse were, "Tell Hannes that the Wissenschaftlicher Mitarbeiter he reads about in the future is really me."<< ... Yes, but E. should have used English language! *>
