John:
Could it be that you have the reciprocal of the 30K
track in mind as coming ashore in New Jersey?
The 30 knot track as seen on Islip and Riverhead Radar
appears to originate within a couple of miles of the crash site and proceeds South-Southwest. Fire Island and the New Jersey shore are located to the North-Northeast.

p.s. As an aside re: Naval vessals or fishing boats, Bob, I've decided. Significant Naval Units all the way. I'll address the Warning Areas shortly.
