The Last Word on San Francisco Conspiracy Theories
This post at Ron Martini's Submarine BBS, from a person I happen to know is a crewman on the San Francisco, should put to rest any further questions on whether or not the San Fran hit another submarine, or if there was an officer senior to the CO on board. As you see from this excerpt, the answers are "no" and "no".
"We did not hit another submerged unit, it was not steel or hull tile we pulled out of our superstructure, it was ROCK, not even coral. We did not have a more senior officer to our Captain onboard, no matter what else you have read on other sites with writers trying to make names for themselves..."
Read the whole post, and remember that this whole episode should be about remembering the sacrifice of MM2(SS) Joseph Ashley, honoring the bravery and professionalism of the Captain and crew, and letting the Submarine Force determine if there are lessons learned that can prevent a recurrence of this tragedy. I'll continue trying to correct anyone on the Internet who says otherwise, but will try to avoid making any further suppositions on the causes or potential outcomes of the investigation on my own (which I admit I have done in the past).
