No additional info is forthcoming, so no. The plane’s actual path was/is well known to investigators, plus/minus the couple of miles that was common to radar and nav accuracy in that era. The earliest moment he could have jumped is also known plus/minus a minute or so which is a few miles. From that point forward there’s a swath a few miles wide and a few hundred miles long that definitely contains Cooper’s jump point.
Yes, there is one suspicious moment shortly after the airstairs were lowered when the whole airplane jumped a bit. Which is the most probable jump point. And which still has a position uncertainty of a few miles.
After that there’s simply nothing more to be known or discovered from the air side.
If somebody ever finds any incontrovertible evidence of Cooper on the ground even that is suspect as to location. How could the evidence have moved or been moved in the 46 and counting years since he jumped?
Even the find of Cooper’s currency in 1980, nine years after his jump, is controversial in that it was in too good condition to have spent the whole time exposed to the elements in the wilds. So where was it during the 9 years, how was it protected by who or what, and how did it come to be in that part of the river? Net of all the dredging and other human activity along there?
