Reminds me of the Canadian Bo105 accident a year or so ago - perfectly surviveable ditching with all egressing before the aircraft sank, then sucumbing to the cold due to inadequate equipment (suits, rafts, jackets)!
212 Man,
Are you referring to the accident of C-GCFU in the Mc'Lure Strait in DEC 2013?
If so it was not a ditching, it was flown into the water at speed due to lack of visual cues.
