TBH, I respect a guy who is sort of "anointed" a leader due to his awesomeness in other areas, but maybe isn't necessarily great at it, more than a certain other type of "leader". Some just THINK they are leaders. Want to be seen as leaders. Try to project that they are, try to "fake it until they make it" by adopting what they think are "standard leadership techniques"... but it just comes off as phony in the end. And it can take some time to filter out who is who, because you can't just take them at first impressions, you have to see them in action in crunch time.
I can think of a certain fighter pilot I knew back in Houston days who really seemed to me at first like one of these try-hard-overthetop-leadership-projection types and I had a terrible first impression of him. But it turned out over time he actually was the "natural born" type. Captain Kirk was probably like this to his crew!
When you first meet them you think, oh man, that guy... but then when the pressure is on, you realize that they really do have The Right Stuff. And after that, they're your Captain. It's rarer than the fakes, though. And both are rarer than the ones who are just promoted into leadership roles by virtue of being "Good People" with technical area performance proficiencies.
