Food for thought....taken from the US FAA discussing Helicopter IFR Operations.
There are sections of the document that could be used to compare the actions of the Pilots in this incident and the Bryant tragedy, the OZ Huey crash...or every other CFIT crash....no matter what jurisdiction they occurred within.
Helicopter flying in marginal weather shall always be fraught with risk.....managing that risk is the key.
