Way off topic i guess, but the Yeager thing is pretty widely known. Has nothing to do with whether he has a degree though. My primary flight instructor was a young test pilot command guy when Yeager was there. They dreaded working with him. The axiom "small egos are rare in aviation" definitely applied in that case evidently. Again, absence or presence of a college degree (or a Masters in the TPC world) would not have anything to do with that situation.

That the guy could "fly the box the airplane came in" was never in doubt, but guys like Hoover, Crossfield, Gus Grissom, Pete Knight, et. all could do the plan, do the math, do the post flight analysis and communicate it in an Engineering vocabulary to the technical staff. That's the job. Different world.
