John,
Interesting observations on AAH. I knew one of the folks who was on the evaluation committee (this was about 15 years afterward), and he told me that when they first set down to evaluate the proposals, one thing they all agreed was that, "We are Not going to select 'Son of Cheyenne'". So, Lockheed had two strikes from the start. I also think that because Sikorsky was able to develop the S-67, which came close to matching AH-56's performance for a fraction of the R&D cost that this embarassed Army leadership and so Sikorsky had two strikes against it as well.
