Besides the obvious selection/survivor bias of good stories. It's likely that if anyone of a population (like say the airforce) is going to have good story telling it's going to be the ones that are the best out of that population in applying themselves (like jet fighter pilots). E.g. I doubt it's that they are good story tellers, I would bet that it's that they are just good at anything they do through applying themselves.
