SAS the pilot was a grunt, probably never seen a ship before.
His "brain" thought: I'll do a zero/zero approach offering minimum exposure time on finals, except, ships MOVE and they move when least expected, so an attempt to land on a hard surface, when that hard surface has just moved down or up 6 feet in a matter of seconds before landing, suggests this is NOT, repeat NOT the way to land on a ship. But when grunts drive, others dive.
Secondly: AFTER, repeat AFTER the helo hit the deck (not before) having made a (shall we say) positive landing, only then did the helo find itself short and the rear gear tangled in the rigging. The pilots then action was to lift away from the short landing by applying collective and voila - the helo pivoted about the gear tipping the cab over.
Make no mistake SAS, this was an approach which led to him approaching too qiuckly for the circumstances and finding at the end of the approach that he didn't have the power to cancel the fwd momentum of the helo (Ergo: Power settling). This is the ONLY reason he collided with the superstructure. Post collision - he tried to reverse away and got snared up.
PS: i love the dynamic rollover idea though - that's a cracker! Were you a grunt too, I guess?
