Well, one was a sub and the other an amphibius ship, I could see how this could easilly happen.
I spent five years on a sub - I do not see how this could happen at all.
No you can't. As a former submarine deck officer, I assure you that submariners stay the H away from surface ships. They know they are smarter than everyone else and don't trust surface sailors [skimmer] to be smart enough to avoid a collision. And if you are steaming in formation, which subs really hate, you keep a really closer eye on them than you would on a known sex offender near your daughter. Subs are extremely maneuverable with big engines and huge rudders, so staying out of the way is really easy, actually. Must have been some idiot on the con. Plus in narrow straights, the CO and navigator would have been there to help out, so three idiots are now flying desks.
Don't know and don't care about the amphib ship. I am only concerned with the dishonor to the silent service.
The amphibious ship should have taken the land route.
