My statements were regarding the fact that had he been honest about his age, the opportunities would have gone to someone else, aka "Pilot Jim Morgan" who would have had broken the sound barrier, written a biography, etc etc.
Yeager would lead you to believe that he, and only he, was capable of such feats. This is not true.
Regarding Hoover and his eye test, I don't know about that story but Hoover was much less a "cowboy" and "show boat" than Yeager and was (is) a big proponent of General Aviation.
I never saw Yeager do anything for general aviation. I did see him write a bestseller (his picture was on the cover, in his flight suit), I did see him as a commercial sponsor for AC Delco, and I did see him continue to fly military aircraft (anything with an "F" in front of it) as long as he could. I did see him either directly or indirectly remind the world how he was such a good pilot.
I never saw him at an airshow doing stunts or actually showing anyone his flying ability. (Hoover did). I never saw him advocate for General Aviation. Heck, I don't recall ever seeing Yeager in a general aviation cockpit by himself.
Yeager told us he was a good pilot. Hoover showed us.
You can form your own conclusions.
