Cooper and McCoy
I don't see much similarity between the two skyjackers. Yes, McCoy refined many aspects of Cooper's heist, or copied them outright - refueling truck on the port side of plane, sitting in the rear of the plane, communication and notes, etc., but the two men seem very different to me.
Involving a wife in thievery is not a good business practice, imho. Not knowing where to stash the money once he got home seems incredibly lame. Not having a game plan for the last part of the heist does not seem to be at the level of preparation and execution that Cooper displayed.
Georger, why do you think McCoy was in McCarran Airport November 24-25, 1971? That's the real kicker to this discussion, in my view.
And why does the FBI have so may conflicting views on this? Himms says McCoy was in LA, Seattle FO says McCoy was eating turkey and watching football games with the wifey and kids in Provo, and Calame says he was coming back from you know what!
