You never heard him self-deprecatingly mock it when the wind blew and exposed his bald spot that one time. He's admitted it's 'a little thin back there'.
No, it's a personality type, in lieu of telling tall tales or embellishing, he tells the same stories over and over. It's annoying till you realize those people can be trusted and don't commonly lie to you.
I was thinking the same thing. I've been on test flight in heavy aircraft where the pilot flopped it so hard, right after we thanked God, we did an over G inspection… Yeah, sometimes the jubilation is warranted.
