Understood, but what would Cooper's forward motion be? distance wise. how much ground would he gain on the way down?
Have you tried the coords yet on Google?
See post 195, above. But after separating from the airliner, Cooper would continue about 1250 feet down the flight track of the airplane until his forward motion (to the south) would have ceased with respect to the air mass. The air mass would have carried him a few hundred feet to the northeast before he hit the ground.
If Cooper impacted at the money find location at Tina Bar, the net result of his movements after separating from the airliner would be about 1000 feet to the south and a few hundred feet to the east. Working backwards from that, he would separate about 1000 feet north of Tina Bar and over the middle to western half of the Columbia River.
Hmmm, so the plane would have to be about a quarter mile short of the Columbia for a "splash one" scenario? that is if the path is correct, and the timing is wrong with where he jumped. if he jumped around the Orchard area, he would of surely survived (if he pulled). it's basically flat. you would think a body would have been found easily in that area if he didn't pull. I've been flying around the area tonite scratching my head.
That money will drive you bonkers as much as the path 
If Cooper or his loot went into the drink, the only place anyone has ever found any Cooper artifact is north of the north dredging spoils site (down stream of that site).
The placard was found practically under the flight path.
Let me try to reply to Shutter and Georger's comments at the same time.
For Cooper to make a direct no-pull impact at the point the money was found on Tina Bar, the airliner would have be flying almost straight south (true course) about the center of the Columbia River. Remember that the river runs almost straight north and south at Tina Bar.
The exact location of the airliner with respect to the river depends on the winds aloft, which are not known precisely at this time. If the winds aloft were zero all the way up to 10,000 feet, the airliner would have had to directly overfly Tina Bar and Cooper would have had to jump about 1250 feet almost straight north of the money find point.
Assuming the winds aloft at different altitudes were all from the southwest, then the stronger the winds, the further west the airliner would have had to be with respect to the money find point. Additionally, the stronger the southwest winds aloft, the closer (in a north/south direction) Cooper would have had to be to the money find point when he jumped.
The placard find location, which was not under the actual flight path, indicated that the airliner was to the west of the V-23 centerline when it separated from the airliner. And the winds aloft that were used in determining the separation point from the airliner involved assumptions. In doing those calculations, I tried to be "conservative" in the sense that the airliner was at least the calculated distance west of the V-23 centerline but could have been some distance further west.
If the Seattle ATC transcripts become available, then new calculations can be done to determine the actual flight path, more accurate ground speeds, more accurate winds aloft, more accurate times and locations, etc..
And Georger is correct, to the best of my knowledge, in stating that nothing related to the airliner has been found south (upstream) of the Tina Bar money find location. And also correct in stating that the money find location appears to be north (downstream) of the dredged materials.
