I am gonna have to side with PB here on a couple of things.
As much as we pride ourselves on being great operators, we all know there are some nukes that are in higher places of authority based entirely on being "Yes-Men/Women" or by virtue of being in for so long that they pick up rank.
As a prime example, and there will be people on this forum that know who I am talking about very quickly, at the Protohell we got in a 25+ year Master Chief who was slated to be an LCC. He was placed into EOOW quals as per S.O.P. and went about his quals in a manner that was more like a PXO than a Staff in training(for those who don't know, PXO are Pilot CDRs that are going on to carriers to be the XO, basically they get the royal treatment). Well it comes times for this guy's Final Watch Board with NRRO and he bombs it royally. No big deal, it happens. #2 comes up and he bombs it again. #3(special permission required) comes and he finally passes it, barely. Most comments are about his watchstanding ability are very poor. However, like PB said about The Don, he was all over cleanliness, stowage, and other aspects outside of perveyance of nuclear power specifics. I fully believed that the plant could be melting down, and as long as all the foxtails were lined up properly and all the watchstanders had a SAT haircut and shiny boots, his world would be nothing but roses. This is just one of a few examples I know about that proves that not all those in the highest levels of leadership(this particular guy went on to be the master chief for the MTS) are techincally compentent in the arena of nuclear power. We see it all the time with Politics, why would we expect anything less from the highest levels of brass, you know the ones that frequently have to deal with politicians.
While I have never met "The Don" in person, I have heard accounts from others that have while in Chucktown, that he does seem to harp more on non-nuclear stuff such as cleanliness. Whether that is just one of his pet-peeves or shows more about his level of competence I do not know. So feel free to add to this or agree or disagree.
