Fairly disappointing response times from SAR - Not sure what the Jigsaw proposed time scales were, but 1hr 45 mins to get the first surface vessel on site seems more than I would have hoped for. And that was a flat calm sea.
Not sure what sea survival times are at night in February but I dare say they aren't too good. The Cormorant Alpha disaster showed some casualties were able to exit the aircraft but died of hypothermia.
