Copterline
You are obsessed with a single theory based on one accident and you have no apparent ability to be objective. Your mass quoting of previous posts does not alter facts. Helicopters do crash or ditch for multiple reasons and crashes may not conform to your somewhat single track theory.
The S-76 series has 6m + flight hours and almost 40 years of operations. It has been a reliable helicopter overall. It is gradually becoming commercially obsolete now, it happens with all aircraft.
You may notice, no one else is debating with you anymore. They have given up because you will only listen to yourself. So post away to your heart's desire. I have lost the will to engage with you any more.
