Why oh why didn't sikorsky take a 61 airframe and replace the running gear and engines with state of the art stuff. Nice big cabin, smooth ride, stable hover platform, relatively benign downwash and above all a proven design. Yes I know, modern regs etc, but it would have made a lovely offshore machine that would knock the 332/225 and 92s into a cocked hat, not to mention make a good SAR machine perfect.
Sorry Nick, I am being facetious - i'll climb back into my box.
