USS McCain was hit mid ship on the port side. McCain obviously was attempting a crossing maneuver in the shipping lane and misjudged the distance to the tanker. Poor seamanship skills by however was in charge.
Now how the USS Fitzgerald got hit is still a mystery to me. My best guess is that both vessels were on auto pilot and all the watches were asleep. I know the navy does not have auto pilot but if the helms man is just holding a steady course and speed it is the same thing.
AND YET, somehow as a child, I was able to take a V-8 powered speedboat and navigate heavy traffic, heavy waves with no radar, no GPS, no help whatsoever. Never ran into another boat, no matter how big or small. And most of the time I was going FULL SPEED.
