I certainly agree with everything you’re saying about the Forrestal fire and have argued the same points many times in the past. Although probably never again.
As for the ship collisions you’re asking about I’m afraid I never followed those stories at all so I can’t help with any info about them.
As for the Ferguson and McCain, from what I've read, it was due to lack of discipline and poor training. I was glad to see the Skippers fired and the Pacific Fleet Admiral, IIRC. But what happened to the Officers who actually let those collisions happen?
