This article from 2004 is interesting:
Sikorsky Forms VH-92 Team for Presidential Helicopter Competition
This program went ahead, and was managed by Nick Lappos. All of the work described was completed and all of the systems performed as expected and confirmed by flight test. ( For those S-92 pilots, it had the 6 force generator vibration attenuation system and was quite smooth no matter where one was seated ). I don’t think that Nick ever received the credit he should have for that project. One very fine flying machine.
I wonder what the per unit cost would have been if the VH-92 had proceeded at that point in time.
