18:00 was the time of the Emergency message from the shrimp boat, apparently when they found the survivors.
Nobody was looking for this helicopter in over two hours that it was missing?
Was a VFR flight plan ever filed with flight following?
From the NTSB report it appears that SP38 was his destination.
Guess what, I believe the rest is...............self explanatory.
I hope ya'll can read a report.
