First of all, I have not followed the D.B. Cooper case at all over the years, and didn't know much about this, until I saw the recent 4-par Netflix doc., D.B. Cooper: Where are you?. Prior to seeing the doc., all I knew about this case was: In the early '70's, a guy stole money & jumped out of an airplane, and hasn't been found since. I did also hear about some of the money (that he stole) being found on a riverbank the early '80's. And, that was it. Note that I have not seen any other docs., about the case, nor have I had a chance to read much of this thread.
So, it was extremely interesting/informative to see the doc. & realize all of the theories that people have had over the years, and also to see how many people have followed this case to the point of obsession. I did not know how much the case has permeated the public consciousness, but am also not surprised at all about this either.
My take on the case & the 4-part doc. - Part 1:
-One of the comments made about the $200,000 that D.B. Cooper stole is that it would be close to $1,000,000 (a million) in today's money. Not sure how true this is. I.e., I know that $200,000 was worth a lot more in 1971 than it is now, but $1,000,000?! I find that unlikely.
-Interesting that the guy who committed this crime wrote his name as "Dan Cooper", but it was inadvertently reported as "D.B. Cooper" early on. And, the name stuck since it sounded cooler/more interesting - LOL.
- I definitely do not think R.R. was D.B. Cooper. As many have said, he was only 28 when the crime occurred, and many who remembered seeing Cooper got the strong impression he was middle-aged (i.e., at least 40). Sure, maybe with make-up, etc. he could have disguised himself to look older. However - despite all of the research done to make R.R. "fit" into the theory that he was Cooper - I don't buy any of it (more about this in Part 2).
When R.R. was younger (based on some of the interviews he gave, that were shown in the doc.) - I think he wanted people to believe he was D.B. Cooper because of the "mystique" it afforded him. Plus, it was evident he enjoyed screwing with authority figures - so, he probably liked the fact that he left people scratching their heads wondering about this.
However, by 2013 when he was being hassled by the documentary makers (who insisted that he was Cooper) I believe he was tired of this. He was getting older, in poor health, and just wanted to be left alone. And, during these interview(s) he actually stated he wasn't Cooper - while sitting at the table outside the small diner/restaurant.
