That ground run briefing had its humorous aspects. IBM had this neat roundish room and it was set up for briefings. I do recall leaning over to the other pilot and telling him that we were obviously in the wrong place and were about to take part in a moon shot or something like it. The only name I recall from those events was an engineer who had matriculated from Sikorsky. He was very talented and did well at IBM, but did have some uphill situations, as few if any of the IBM folks knew much about aircraft, let alone helicopters. For the special ops machines, they had to provide a flight director display, with computed three D commands and connected with all the nav systems on the machine. Their abysmal performance with that subject area was likely the reason their exec thought we were communicating with Boeing as it turned out that their pilots and our pilots were saying exactly the same thing, and using the same language. Well, of course.
