To say that McCoy was "far more advanced than Cooper" is only partially true in my view. Yes, McCoy's decision to hijack a plane enroute to the west coast from Denver was an improvement over Cooper's short Portland-to-Seattle hop.
As for describing McCoy as a "deeply confused and an deluded individual," again, I only agree partially. McCoy was suicidal and hospitalized in the fall of 1971, and that supports your characterization somewhat, but not fully.
He was clearly confused about what to do with the money and his gear once he got back home. He had no end game, at all, as far as I can see.
But his execution of the hijacking was excellent - no evidence of delusion or confusion there. Anticipating the tracking devices in the chutes and using them as decoys was brilliant. Bringing a duffel bag big enough for half a mil, another.
But telling his wife for months that he was going to do the skyjacking was not so smart. It shows the soft underbelly of his psychological structure. He didn't have the full mental and emotional compliment to be a truly successful hijacker.
One of the items that came out of my remote viewing sessions that I particularly enjoyed was when one of the DBC personas told me that he and his colleagues don't need to talk about their work. Hence, they don't. I remember his line that "If you need to talk about the operation, then you can't be part of us. No one in these kinds of operations is flabby or gabby. If you are, you're gone."
Also, I thought the description of his living environment was also appropriate for a Cooper-style operation - living in a military area, with a wife who is conditioned not to ask her husband about his military work.
Maybe DB Cooper lived in the Fort Bragg area or North Carolina, and one of his missions was to fly to South America and deploy from a 727 to assassinate local officials whom the USG didn't like.
