What you guys are talking about with regard to being gutsy to talk back is what is referred to as the "halo effect" in USAF CRM classes. Essentially, a junior guy assumes that since his aircraft commander has a crap load of experience, he must know what he's doing, regardless of the fact that the junior guy is about to **** his pants. In those cases, the junior guy should voice his concern, if indeed he just doesn't know what's up, the senior guy will calmly explain why it's ok to do what he's doing and the back end will most likely back him up. If the senior guy is indeed over streching his bounds, in my experience the back end will cry foul very loudly.
