For Cooper to have had help certain things need to fall into place. he would need to time the flight since he didn't plot any path. McCoy was very precise in landing exactly where he wanted to land. if he tossed things into the river one would think he was very close to the river, or it's a waste of time going out of his way.
If he had help, why would he toss things in the river, unless they were headed away in that direction. I would think leaving the stairs down would cause more concern than it would help in his escape. as soon as the stairs came down, they should of been saying, "he's getting ready to jump" even if he didn't they would be ready for him IMO? they were supposed to flash the lights when they thought he jumped?
Personally, I'm not trying to change the flight path. I'm open to anything that makes more sense as to how the money arrived on the beach. you must go through all possible scenario's in order to come to any conclusion. leave no rocks unturned.
1) We have R99 making a lot of sense to why that path would be taken.
2) We have someone who was involved with the case stating the same as R99.
3) We don't have any conclusions of how the money got there in the first place.
4) We have people believing a plant, but the money wasn't really buried. why not just toss it on the beach?
5) 40+ years later and they still can't find planes?
This may not be that complex.
We know Cooper bailed btwn Seattle and Portland - his original plan? That is what he did. He didn't wait to bail near Reno! He may not have known where he was going to land ... just bailed, but he began getting ready to the bail the minute the chutes and the money arrived, got door open, and stairs out, and jumped.
What he DID was get ready asap and jumped. Time alone dictates he knew he was somewhere between Seattle and Portland timewise! He instructed the pilots to give him a stable jump from 10k feet at around 200 mph. His last requests were to 'make the plane stable' .... " we think he is going to jump" .... and he did.
His stated motive "I have a grudge".... "has nothing to do with NWA". "The money is not important". That IS what he said.
The jump was survivable. He assumes he is over land - has no reason to think otherwise.
Only the placard and some money were ever found despite searches by thousands all over God's creation over years of people searching!
He said it was a grudge so it's political. He said the money "is not important" - his exact words.
His acts and his words fit 100% with the outcome. The only thing missing is how money gets to Tina Bar.
Occam says he threw the money into the Columbia himself. He said the money was not important!
The minute he gets rid of the money it can never be tied to him, can it.
It may be an audacious thing for him to do (something you would not do _ something people who value money might not do) but he is exorcising a political grudge. He said "the money is not important"! Sounds to me like he is making a political statement and wants to be a "hero" and make a point and get away with it! And he tosses the "establishment's money" into the Columbia as a final act of defiance and contempt! I knew a hundred guys in the seventies who wold do something like that if they could, and laugh all the way home. And that scenario is exactly how a lot of political types in the 70s took Cooper's hijacking.
A bomb and a political principle and an audacious act _ was the stock & trade of political terrorists in the 1970s.
In fact this guy could have been from Seattle and by throwing his loot in the Columbia he shifts the focus of attention further south back to Portland ... far away from home. He may have thought the money or parachute etc would be found .... a lot sooner.
