Texas is around, as is North Carolina. There are a couple still around - but you're right, there not one from a land-locked state.
That sort of tendency you speak of isn't confined just to that part of the Navy. In my agency, during the Iowa investigation, there was a lot of buzz about how quickly the two "miscreants" were identified following the incident. I, who had a few years under my belt by then, was mystified at how quickly these two crew members could be identified with such certainty by the senior investigators in Norfolk who were handling the probe for the DON. Won't go into that aspect any further. I was quick to note we had not as an agency (apparently) engaged the independent consulting services of anyone, within the Navy or Army or elsewhere, who had any experience with these guns or their support systems - that is, beyond those already provided by the Navy, who may have had their own viewpoint to advocate. The Army did operate them for many years within the Coast Artillery Corps. I know because Dad was one of the guys who did. There were a number of CAC veterans, plus their Association, who also could have been consulted but were not. There was a rush to blame people rather than equipment, propellant, and training, which turned out to be the causes after all - just as I maintained at the time but was dismissed. It was an overram of the powder bags, caused by equipment problems and not-quite-completed training, that caused the explosion. It doesn't bring back the dead, but it does do them and their families justice and clears them of blame. You're absolutely right about the command environment on that ship. For a first-rate look at the circumstances leading up to the accident, the investigation and the aftermath, read "A Glimpse of Hell," can't remember the author, it's in storage over on the mainland. AFAIK nothing more was ever said about the two investigators who were running the show for my agency. This incident is one of the two big reasons - the other being Tailhook - my former agency changed its name. Sandia National Laboratory solved this one, not my former agency.
