R99:
Why do you suppose Flight #305 dog-legged around PDX from the East to the West and back to the East?
That "dog-legged" or "segmented circle" around the west side of Portland from what is now the Battleground VORTAC is NOT something that would have been done on that flight by that flight crew.
While on the ground in Seattle, the flight crew mentioned some possible "alternatives" to flying down Victor 23. They had been informed that the Chief FAA Psychologist had predicted that Cooper would take a hostage with him and then blow up the airliner as they jumped. Consequently, the crew did not want to fly over a densely inhabited area if they could avoid it.
When the airliner reached the Mayfield (now Malay) Intersection near Toledo, the most logical thing for them to do would be to head almost straight south and rejoin Victor 23 at or near the Canby Intersection. If they did that, they would pass almost directly over Tina Bar.
If the precise flight path was available, and it should be in the un-redacted Seattle ATC transcripts, and if it supports the straight line bypass on the west side of Portland, then Cooper's jump point can easily be pinpointed. At the same time, as I have pointed out previously, the geographical and topographical characteristics of Tina Bar are so unique that they have a real story to tell. And that story may include evidence that Cooper died in the jump as a no-pull.
Just from a general inspection of Georger's photography of the Tina Bar area, plus topographical information, it is obvious to me that Cooper could not have jumped at a point north (or downstream) of Tina Bar or further south (upstream) than the Flushing Channel to Vancouver Lake. And he probably landed on solid ground but very close to the east Columbia River shoreline.
There is also evidence on the so-called FBI maps that support a straight line bypass of Portland on the west side. In addition, the National Guard T-33, the USAF F-106s, and Himmelsbach and his helicopter all headed to the southwest side of Portland.
If the un-redacted Seattle ATC transcripts aren't made available within a reasonable time, I will expand on the above as much as the available data permits.
Actually, at this point in time, there seems to be very little related to the redactions that is not known except for the exact times and aircraft locations that are necessary to determine an accurate flight path.
Did anyone ever ask Rataczak or Anderson about their flight path as they passed Portland?
