Andy, just to be clear I didn’t say it was hacking (but do not entirely discount it). Rather than running into a fire hydrant let’s consider the possibility that due to several other possibilities the environment was more like an Indy 500 race. I. e., I am not ready to hang the crew on the bridge until we have more info (and with the several most recent fatalities it would be today’s equivalent of a hanging).
Well, you can entirely discount it because ship is under the total control of an OOD with eyeballs and a tanker, even 5 nms away us a looming hulk that you can't avoid seeing. And the things don't maneuver so well.
And no the sea-lanes are not bumper to bumper with dodgem merchant vessels. And a Burke class DDG has far more power and maneuverability, even if the tanker were bent on having a collision. It's like chasing a Ferrari with a Zamboni.
