Among rotorcraft there are few more handsome examples than the S76 - in fact only one in my view. Helicopters, in general, (to me) are fairly ugly contraptions but I do believe Sikorsky got it right in terms of exterior design aesthetics.
I am aware that it was only in the 'B' model that decent performance was to be realised and that this was at the expense of thirsty engines. I remember too the AS365 .. and was 'given a go' by a chap who I think was called David Sale. I had visited McAlpine's in the early 90's (perhaps 1990) to consider the Dauphin for a client and was handed over to David who at the time was flying with P&O. I actually didn't find it as smooth as the 76 but .. perhaps that ship was poorly tracked? Also, with a good load on board, the Dauphin made an unbelievable din when approaching at speed; not that the 76 was quiet mind you!
I do hope that Sikorsky 'get it right' with the 'D' model but .. my impression is that the VIP/Corporate requirements of the future are going to lean towards a 4 x 2 arrangement where either two seats (or a bench seat) are available behind the traditional club 4 - a little like the EC145 interior (below) but with more space and with the club 4 isolated from the rear 2-3 seats.
Regarding Dauphins (old and new) the crew at Starspeed certainly seem to like them.
