I am a Navy Veteran - I have been out to sea plenty. We had people go overboard and the thought of that always scared me. If you have ever been out there whether calm seas or waves, it is nothing but a blank canvas for miles and miles.
There have been plenty of instances where a guy falls off the ship and people saw him fall.....so man overboard is sounded. Yet, the choppers still have a hard time finding the person, if at all.
The sea is just a beast.
If a coast guard chopper would have spotted them and shined a light on them, they would have been rescued. I wasn't there, don't know what happened, but a coast guard rescue crew is several members deep. It would take all of them to decide to do nothing. Not gonna happen.
Nobody will lose their job or get disciplined. In fact, I would bet that a bunch of medals will be awarded for the effort.
