I read the report when it came out. Part of the blame was the condition of the powder. A similar explosion from the same causes had happened aboard a heavy cruiser a few decades before.
That's the Navy pointing fingers at everyone and everything except the Captain.
first is was supposedly a suicidal homosexual seaman (semen?); thne it was the powder. Fact is they re-mixed the powder before they sent it out and re-bagged it.
