I have read that the Traffic Separation Scheme at Singapore is one nautical mile wide. It is the purplish colored stripe in this ship tracking video.

As the Alnic MC enters the Traffic Separation Scheme (TSS), the tanker appears to be about one half mile starboard of the TSS on a steady course towards Singapore.
So how does the USS McCain manage to get itself in front of the Alnic MC and get hit?
