I flew every model from the A to the C+. The S-76 has now had its day, but out of all the types I’ve flown, they ride the sky bumps the best. I never did get to trust that auto hover over lumpy sea, though!
I think SK dropped the ball with the D Model. They spent too much time and effort on the Comanche and the early Presidential bid project and promised delivery dates for the new D became ever more distant. By the time they woke up the AW139 had run past them and away.
