>>>I once read a reference to the bio released during WWI, and the Germany censors let slip a passage that for all practical purposes, described the sexual release von Richthofen said he got from downing planes
You might be misinterpreting the section where he said he was a master at working the joystick.
Not me, but the guys that actually read the bio. I do believe they said something about the censors probably not being familiar with Freud, though.
