Yeah, I had to laugh because Yeager wasn't up to the test himself and he is supposed to be a real "warrior" and all that hoopla TRI spews.
I had to laugh at him blaming the ammo for his limp wristing. Why would you do a 1000 round test like that and use cheap ammo? So that if anything goes wrong, you can blame the ammo!
It seems pretty obvious to me that he was kind of joking when he made that statement. I don't think he was actually serious.
