“Ramming”? By a CONTAINER SHIP? BWAHAHAHAHAHAHAHA!!
*Ahem* Now to get serious.
The collision occured in one of THE busiest ship lanes in Japan. Both ships were probably on autopilot. Which, OBTW is only as “foolproof” as the fools who program it. Night watchmen? Didn’t help the Titanic much.
2:00 AM on a moonless (probably) night. Stupid? Yes. Preventable? Definitely. Human error on one or both sides? Most Definitely. Accident? Without a doubt.
Ever been on a Navy ship? They don't have an autopilot.
