So did Nick leave Sikorsky after disagreements regarding the S92?
No. You're on the wrong track completely.
Nick was tempted by the new challenge offered by Gulfstream - heading their Government Programmes division - but was very reluctant to leave Sikorsky. Gulfstream was determined to recruit him and eventually offered a package that no-one in their right mind would have turned down.
(He was subsequently head-hunted by Bell who were also extremely keen to recruit him, and eventually succeeded.)
has returned just when they really need to rebuild their reputation.
If that's the case, then there's no better man to do it.
