No doubt he is a scum bag POS. I saw his picture. He had no wings. How does a scum bag POS like him, get to be a 4 star General, without being a rated pilot? I don’t think it happens very often.
Two things: first, Hayden was a GW Bush appointee. Second, he could use a membership in Hair Club for Men.
Pretty sure his MOS for his entire career was Intelligence.
There are plenty of Air Force MOSs that don’t require flying.
