Life is not fair....the Sea is a very unforgiving place.
Yes, Closure is good and it tragic the families and friends of the two lost Missing Crewmen are having to go through this but One must be realistic. There has been a tremendous amount of searching going on in a very inhospitable environment.
Fishermen, Sailors, and others who venture out all understand the risks and odds of this happening.
The Accident Report will be written in time and the story will be told.
As for the Missing Crewmembers....there is always hope no matter how slight that they will be found and the family achieve some closure in that regard.
