Water levels, Current, misreading the lights----Hummmm.
It is safe to safe, conclusively, the bridge went down and the Pilot did not want that.
Can't turn back the clock.
I believe that the facts will show that water levels and current were the culprits.
Thos boats are big and when they get to going sideways there is not a lot ANYBODY can do to change the direction.
