Controversial CO's name pulled from O-6 selectees list. Do you think this was warranted?

This is how the system is supposed to work whenever there is a question or allegation.

I'm glad that there is an investigation. The perception is that, things get swept under the rug for certain persons at certain levels of rank. I couldn't say yea or nay, because I don't know the factual evidence of the case. However, if in fact her negligence caused the death of those pilots, A HELL of a lot more than a non punitive letter should have transpired.

There is an old saying: "$#it happens".
Sometimes it happens to good people.
Question is, did the incident occur due to her mishandling her vessel at sea, or because the ocean gets a vote?
Should the Navy hold this against her forever? What are the precedents set by previous similar incidents. Surely this has happened before.
Without the facts of the case, we should not cast judgment. The senior officer who did have the facts of the case judged that a non-punitive letter was all that was warranted. Since the Navy does not screw around with incidents like this, I can surmise that the senior officer knows something we don't.
That's why we have this process.
