No-one denies that returning into a crashed, semi submerged helicopter was a brave move, but the implication that it was in any way a controlled ditching and logical set of moves is bulltish.
If the Squirrel was landed under control then the first action would/should have been to inflate the floats and prevent it rolling: that's what they are for. The video indicates that after the impact with the cover the pilot and pax were along for the ride. I'd be very doubtful that there was even a conscious decision to fly away from the deck, but no doubt Q can come along in one of his posts here and tell us first hand.
Hopefully without the self promotion.
G-SASY, no doubt you will support your friend/relative but ditching instructions for a Robinson should not be seen as relevant to ditching a Squirrel with flotation gear.
