Was the captain blameless?
The Captain made his decisions based upon his experience and the information available to him at the time as each and every Captain does.
It has been shown after the event some of the information given to him was Incorrect
We were not there therefore, we cannot question whether or not his decision was correct or not.
Further questioning, review, speculation will not change what happened, the investigation report or subsequent investigations.
Nor will any of the continuing questioning, expression of opinion or conjecture here have further investigations or court reopen to look further into the subject.
Perhaps it is more than past time to let all Rest in Peace!
